Abstract John W. Mauchly (1907-1980) was a physicist, teacher, and a leader in the development of computers. With J. Presper Eckert, he invented the Electronic Numerical Integrator and Computer (ENIAC), the Electronic Discrete Variable Automatic Computer (EDVAC), the Binary Automatic Computer (BINAC), and the Universal Automatic Computer (UNIVAC). This first installment of Mauchly's papers documents Mauchly's youth, education, early career at Ursinus College, his work at the University of Pennsylvania Moore School of Electrical Engineering, his partnership with J. Presper Eckert, with whom he formed two companies, the Electronic Control Company (ECC) and the Eckert-Mauchly Computer Corporation (EMCC), and his work through 1959 with Remington Rand/Sperry Rand after its purchase of EMCC in 1950. Early work in programming, coding, compilers, routines and subroutines, and most importantly, the application of electronic computers in government, business, and industry, as well as the history of the computer, is well documented. Moreover, this collection provides a glimpse into the

Biography/History

John W. Mauchly was born on August 30, 1907, to Sebastian and Rachel (Scheidermantel) Mauchly in Cincinnati, Ohio. He moved with his parents and sister, Helen Elizabeth (Betty), at an early age to Chevy Chase, Maryland, when Sebastian Mauchly obtained a position at the Carnegie Institute of Washington as head of its Section of Terrestrial Electricity. As a youth, Mauchly was interested in science, and in particular with electricity, and was known to fix neighbors' electric systems at the age of 13 or 14. Mauchly attended E.V. Brown Elementary School in Chevy Chase and McKinley Technical High School in Washington, DC. At McKinley, Mauchly was extremely active in the debate team, was a member of the national honor society, and became editor-in-chief of the school's newspaper, Tech Life. After graduating from high school in 1925, he earned a scholarship to study engineering at Johns Hopkins University. He subsequently transferred to the Physics Department, and without completing his undergraduate degree, instead earned a Ph.D. in physics in 1932. From 1932 to 1933, Mauchly served as a research assistant at Johns Hopkins University where he concentrated on calculating energy levels of the formaldehyde spectrum. Mauchly's teaching career truly began in 1933 at Ursinus College where he was appointed head of the physics department, where he was, in fact, the only staff member. According to John Costello, Mauchly "became a campus celebrity--if not a faculty favorite--for the irreverent Professor Ho-Hum lectures he used to deliver on the last day of class before Christmas," (Costello, page 50). In addition to his teaching duties, Mauchly sought automated ways to manipulate weather data. After some experimentation on his own, he visited John V. Atanasoff, an Iowa State University professor and inventor of the Atanasoff-Berry Computer (ABC) which used vacuum tubes. Because the ABC machine was not fully electronic, Mauchly decided to continue his own research and experimentation. In the summer of 1941, Mauchly took a Defense Training Course for Electronics at the University of Pennsylvania Moore School of Electrical Engineering. There he met the lab instructor, J. Presper Eckert (1919-1995), with whom he would form a long-standing working partnership. Following the course, Mauchly was hired as an instructor of electrical engineering and in 1943, he was promoted to assistant

- Page 4 - John W. Mauchly papers professor of electrical engineering. Following the outbreak of World War II, the United States Army Ordnance Department contracted the Moore School to build an electronic computer which, as proposed by Mauchly and Eckert, would accelerate the recomputation of artillery firing tables. In 1943, Mauchly and Eckert began building the ENIAC, Electronic Numerical Integrator and Computer, "an electronic machine to replace mechanical devices" (Costello, page 45). Mauchly has been described as the visionary and Eckert the engineering mastermind of Project PX, the name of the ENIAC during development. ENIAC was not completed until 1946, one year after the end of the war, and was first used by the U.S. Army at Aberdeen Proving Grounds in Maryland for ballistics testing in 1947. While still at Penn's Moore School, and even during the construction of ENIAC, Eckert and Mauchly were also working on the "next computer," the Electronic Discrete Variable Automatic Computer (EDVAC), which Mauchly describes as "the outcome of lengthy planning in which Eckert and [he] deliberately tried to overcome many problems of storage and control which were evident in the hasty 'state-of-the-art' ENIAC System," (Mauchly, Datamation). However, in 1946, Eckert and Mauchly resigned from Penn as a result of a patent dispute over "changes in the way in which ... contracts were administered at the University and changes which the University wished to make in the terms of [their] employment" (Mauchly, Resume). Together, they immediately formed the Electronic Control Company (ECC) which was later renamed the Eckert-Mauchly Computer Corporation (EMCC) when it was incorporated on December 22, 1947. During this period of Mauchly's career, he was denied security clearance which made his work difficult and resulted in his frequently working from home. Although the reasons for Mauchly's security clearance problems were never disclosed, Kay Mauchly suspected, based upon Mauchly's FBI file that it was because he subscribed to Consumer Reports which was declared communist-oriented, or because some members of his staff were considered security risks. Despite this challenge, Eckert and Mauchly introduced, in 1949, the Binary Automatic Computer (BINAC), which used magnetic tape rather than punched cards and stored computer programs internally. By 1950, the Universal Automatic Computer (UNIVAC) had been developed. In February 1950, EMCC was purchased by Remington Rand, and EMCC became a division of Rand. The UNIVAC went on the market in 1951 and is considered the first widely used commercial computer able to handle both numerical and alphabetical data. The first order for a UNIVAC came from the United States Bureau of the Census. In 1955, Remington Rand merged with Sperry Corporation and Mauchly became the head of the UNIVAC Applications Research Center (UARC), the UNIVAC division of the Sperry Rand Corporation. Applications research was a field for which Mauchly had long campaigned, and while heading UARC, Mauchly, along with his colleagues, developed C-10 programming code as well as many other "component parts for a commercially useful data processing device of high speed and general scope," (Mauchly, Resume). UNIVAC II was introduced in 1957. Documents within the John W. Mauchly papers indicate that Mauchly and Remington Rand/Sperry Rand did not always agree on the direction in which the company was headed, although productive work appears to have been achieved. In 1959, Mauchly left Sperry Rand and started Mauchly Associates, Inc. One of Mauchly Associates' notable achievements was the development of the Critical Path Method (CPM) which provided for automated construction scheduling. Mauchly also set up a consulting organization, Dynatrend, in 1967 and worked as a consultant to Sperry UNIVAC from 1973 until his death in 1980. During the early 1970s, Sperry Rand and Honeywell underwent litigation regarding the invention of the electronic computer. According to Kay Mauchly, "Sperry was suing to collect royalties, charging infringement of the ENIAC patent [and] Honeywell wished to avoid paying royalties by claiming that the

- Page 5 - John W. Mauchly papers ENIAC patent was invalid because of prior art (among other things) and charging Sperry with restraint of trade," (Mauchly, Kathleen R., page 117). The court eventually ruled that Mauchly and Eckert had not invented the electronic digital computer, but that instead, John V. Atanasoff was the inventor. Many critics of this ruling say that there are very few similarities between Atanasoff’s ABC and the ENIAC; and Kay Mauchly states that papers and "physical components of the electronic computer that Mauchly was building during the time he was teaching at Ursinus College ... alone are evidence that Mauchly's concept of an electronic 'computer-calculator' predated any association with John V. Atanasoff and led directly to the design of the ENIAC," (Mauchly, Kathleen R., page 117). John Mauchly died on January 8, 1980, in Abington, Pennsylvania, during heart surgery and following a long illness. His first wife, Mary Augusta Walzl, a mathematician, whom he married on December 30, 1930, drowned in 1946. John and Mary Mauchly had two children, James (Jimmy) and Sidney. In 1948, Mauchly married Kathleen Kay McNulty (1921-2006), one of the six original ENIAC programmers; they had five children Sara (Sallie), Kathleen (Kathy), John, Virginia (Gini), and Eva.

Series I. Youth, education, and early career. Scope and Contents note

This series documents John W. Mauchly's life from 1908 to 1941 when he began working at the University of Pennsylvania Moore School of Electrical Engineering. The series is divided into four subseries: A. Life and education in Chevy Chase, Maryland, B. Life and education at Johns Hopkins University, C. Teaching career at Johns Hopkins University, and D. Head of Department of Physics, Ursinus College.

Subseries A. Life and education in Chevy Case, Maryland, includes material from Mauchly's very early childhood through his high school years. The earliest materials in the subseries consist of letters from family members and reveal a close-knit family. Included is a remarkable notebook of codes and ciphers dated 1918. The notebook also contains examples of Mauchly's early methodology for creating standardized data in the Girls' and Boys' "Quiz Book" in which his friends' likes and dislikes are recorded. The bulk of the material in this subseries, however, dates from 1920 to 1925. Documents include his financial accounts; correspondence, mainly with a sizable group of friends; his diaries; his school coursework, grades, and activities; and other memorabilia. Of note are Mauchly's diaries in which he records minute details about his daily life, including his sleep patterns, daily activities, and lists of friends, correspondents and people with whom he spent time. These diaries, along with his notebook, reveal his early interest in data of all types and document his methodology for collecting and organizing information; they provide a fascinating glimpse into his early life. One particular highlight is his record of the "Somerset Affair," compiled after his mother suggested that he spent too much time away from home. Using data he collected about his times of arrival and departure, he successfully defended himself against her accusations. Mauchly's personality, popularity, and sense of humor are apparent in this portion of the collection.

Subseries B. Life and education at Johns Hopkins University, documents Mauchly's undergraduate and doctoral work in the Baltimore, Maryland institution from 1925 to 1932. Because Mauchly saved so much of his own material, the subseries provides a clear picture of his life as a student. Researchers will find evidence of his hobbies, friendships, research, schoolwork, and writing. A large portion of this subseries consists of correspondence which, as in the first subseries, indicates a strong network of

- Page 10 - John W. Mauchly papers Series I. Youth, education, and early career

family and friends. Many of the same correspondents from his high school years appear in this group of materials. In 1930, Mauchly married Mary Walzl (died 1946), and this subseries includes materials relating to both John and Mary Mauchly. Materials that relate only to Mary are housed in a separate series (not yet available). In addition to Mauchly's schoolwork at Johns Hopkins (which is documented with class notes, lab records, official notices, and transcripts), Mauchly also taught a Physics I class and worked as a tutor. Researchers unfamiliar with Mauchly may be interested in his poetry, submissions to Black and Blue Jay, and "Ye Knews-Letter" which indicate a strong interest in the humanities and show his sense of humor and personality. Of particular interest is the document entitled "Girls to Whom I Have Given Special Attention," which includes a list of women, the reason he gave each one special attentions, and, presumably, the number of times the special attentions were bestowed.

Subseries C. Teaching career at Johns Hopkins University consists of only a small amount of material, dating from 1932 to 1933, the year after earning his Ph.D. at Johns Hopkins and before starting his career as a professor at Ursinus College. Oddly, there are no records of his actual teaching, but instead this group of materials contains his typical correspondence from family and friends; financial records; and letters from Mauchly to numerous institutions and individuals seeking permanent employment, which, as a result of the Depression, was difficult to obtain.

Subseries D. Head of Department of Physics, Ursinus College dates from 1933 to 1941 and documents Mauchly's career as a professor at Ursinus as well as his entrance, more largely, into the community of physicists and mathematicians. The material is further organized into Correspondence; Clippings; Notes and datasheets; Organizations, memberships, and conferences; Personal and family documents; Teaching; Writings by Mauchly; and Writings by others. The correspondence in this group of materials is largely professional and there is rarely a large group of letters to or from any one person, with the exception of correspondence with John DeWire, H. Helm Clayton, Dr. Irving, and S.S Wilks, to name the most prominent. Researchers will find Mauchly's correspondence with John V. Atanasoff in box 3, folders 28 and 32. As is documented in other subseries, his network of family and friends was extensive. The Notes and datasheets grouping shows many of Mauchly's interests and includes his notes, formulas, math problems, as well as data gathered from other sources. Many of these interests were life-long, in particular Mauchly's interest in weather and forecasting; therefore, researchers should consult the Notes and datasheets groupings in other series for later research on the same topics. As Mauchly became more involved in his profession, both as teacher and scientist, he increasingly joined societies and attended conferences for his continuing education, which in this subseries are arranged alphabetically by organization name. There are fewer personal and family documents in this subseries, but his correspondence with his mother, sister, wife and friends still provides substantial information

- Page 11 - John W. Mauchly papers A. Life and education in Chevy Chase, Maryland

about his personal life. Mauchly's teaching career, which according to documentaries and published articles, was exciting, fun, and innovative, is documented through course material, petitions by students for Mauchly's pre-Christmas lecture, and trips for physics classes. Finally, this subseries contains writings by Mauchly and others.

This first series provides an excellent foundation for research for those interested in who Mauchly was and how he thought, learned, educated, and problem-solved.

Series II. Moore School of Electrical Engineering, University of Pennsylvania. Scope and Contents note

From 1941 to 1946, Dr. John W. Mauchly attended courses at, was employed as an instructor by, and built (with J. Presper Eckert) the first electronic general-purpose computer at the University of Pennsylvania Moore School of Electrical Engineering. His work during this time is documented in Series II. Moore School of Electrical Engineering, University of Pennsylvania. The series is further divided into A. Clippings; B. Correspondence; C. Moore School records; D. Notes and datasheets; E. Organizations, memberships, and conferences; F. Patents (not Eckert or Mauchly); G. Personal and family documents; H. United States Government records; and I. Writings by others.

Researchers should be aware that there is very little material regarding the Electronic Numerical Integrator and Computer (ENIAC). Because this computer was constructed under the auspices of the United States Army, Ordnance Corps, Research and Development Command during World War II, material related to ENIAC’s development would have been classified and Mauchly would not have been able to keep his records. Instead, these records are probably retained by the National Archives. Likewise, there are no records about the women programmers of ENIAC in this collection and there are very few records by or about J. Presper Eckert's work with Mauchly on the development of ENIAC in this series. Researchers interested in ENIAC should consult the ENIAC Patent Trial Collection, 1864-1973 (bulk: 1938-1971), UPD 8.10 and the Moore School of Electrical Engineering Office of the Director Records, 1931-1948, UPD 8.4 at the University of Pennsylvania Archives and Records Center.

Subseries A. Clippings contains newspaper and magazine clippings about a few items in which Mauchly was interested or involved. Of particular note are the clippings about the ENIAC after it was unveiled to the public. As is the case throughout the collection, a significant portion of material relates to weather and weather-forecasting.

Subseries B. Correspondence, includes both personal and professional letters. The professional correspondence is not particularly rich and, generally speaking, there is not a significant number of letters to or from any one particular correspondent. Researchers should be aware that correspondence from colleagues at the Moore School will be found in C. Moore School records.

Subseries C. Moore School records contains the bulk of materials in this series. While there is little information on the ENIAC, this subseries documents the workings of an institution during war-time and the teaching of engineers under the auspices of the Armed Forces Training Program. In particular,

- Page 31 - John W. Mauchly papers Series II. Moore School of Electrical Engineering, University of Pennsylva...

the bureaucracy resulting from working both for an academic institution and for the military is evident in many documents. Researchers will find work-related financial records; coursework from the classes Mauchly took during the summer of 1941; information about the Moore School lectures delivered in 1946; publications by the Moore School, including those relating to the Electronic Discrete Variable Automatic Computer (EDVAC), reports on the ENIAC, and published versions of the Moore School lectures; and coursework from the classes that Mauchly taught during his tenure at the University of Pennsylvania. Researchers should be aware that the student work and exams (located in box 9, folders 13-16, 19, and 20-24) are restricted due to the Family Educational Rights and Privacy Act of 1974. Researchers will also find intramural correspondence, most of which relates to requirements of the United States Army and/or the University for reporting attendance, grades, or other administrative matters. Of importance, however, are both Mauchly's resignation letter which includes his reasons for leaving the University of Pennsylvania and the dean Harold Pender's acceptance of Mauchly's resignation (found in box 7, folder 29).

Subseries D. Notes and datasheets shows many of Mauchly's interests and includes his notes, formulas, math problems, as well as data gathered from other sources. Many of these interests were life-long, in particular Mauchly's interest in weather and forecasting; and therefore, researchers should consult the Notes and datasheets groupings in other series for later research on the same topics. In this group of notes and datasheets, Mauchly's interest in and work with the development of the computer industry is well documented.

Subseries E. Organizations, memberships, and conferences demonstrates that as Mauchly became more involved in his profession, as a teacher, a scientist, and an expert in the field of computers, he increasingly joined societies and attended conferences for his continuing education. Researchers will find that he continued to associate with these organizations throughout his career, and should therefore, consult the subseries titled Organizations, memberships, and conferences in other series for later records.

Subseries F. Patents (not Eckert or Mauchly) contains collected information regarding other patents.

Subseries G. Personal and family documents includes records about Mauchly’s home life, including financial records, medical records, insurance records, poems and humorous stories, puzzles, and voter registration cards. Of interest may be the documents which record life during World War II, including both the Selective Service registration cards and the ration books.

Subseries H. United States Government records contains records from an elementary course in cryptanalysis offered by the United States Navy; memos and passes from the Naval Ordinance

- Page 32 - John W. Mauchly papers A. Clippings

Laboratory in Maryland, and reports for the Mathematical Computing Advisory Panel of the Office of Research and Inventions, as well as a few other publications. During World War II, Mauchly was associated with the United States Government (for the most part the United States Navy) through his work with the Moore School.

Subseries I. Writings by others includes papers, articles and reports which Mauchly read and kept. These writings are frequently not in published form, but appear to be items sent specifically to Mauchly. In this group, there are several writings related to the ENIAC, including those by J.G. Brainerd, Morris Freedman, and L.E. Levick.

Series III. Eckert-Mauchly partnership. Scope and Contents note

Series III. Eckert-Mauchly partnership dates from 1946 to 1959 and is the most extensive group of materials in John Mauchly's papers. During this time, Eckert and Mauchly created two companies, the Electronic Control Company (ECC) which was in existence from 1946 to 1947 and the Eckert-Mauchly Computer Corporation (EMCC) which was in existence from 1947 to 1950. In 1950, the Eckert-Mauchly Computer Corporation was purchased by Remington Rand (which merged with Sperry Corporation in 1955), the company for which Mauchly continued to work until 1959.

This series is divided into A. Electronic Control Company (ECC) records; B. Eckert-Mauchly Computer Corporation (EMCC) records; C. Remington Rand/Sperry Rand records; D. Notes and datasheets, E. Organizations, conferences, and memberships; F. Personal and family documents; G. Talks by Mauchly; H. Teaching: "Mathematics for Digital Computers" at Temple University; I. Writings by Mauchly; and J. Writings by others.

Subseries A. Electronic Control Company (ECC) records contains material from that business venture. Researchers will find company information such as agreements, policies, personnel records, financial information, and publicity. The subseries also contains information on computers, including the Electronic Numerical Integrator and Computer (ENIAC) and the Electronic Discrete Variable Automatic Computer (EDVAC). Files on potential projects and contracts generally include correspondence and sometimes include proposals. It is frequently unclear when Electronic Control Company actually received a contract.

Subseries B. Eckert-Mauchly Computer Corporation (EMCC) records contain all existing material from that business venture. Researchers will find company records including board of directors material, business plans, bylaws, company histories, financial records, information about potential office space, patent applications, personnel records, and tax records. Of particular interest is the material relating to the Eckert-Mauchly Employee's Association and Roundtable. Agreements relating to a possible merger with American Totalisator Company, Inc. and the actual purchase of EMCC by Remington Rand can be found in this subseries. Files on the Binary Automatic Computer (BINAC) and Electronic Discrete Variable Automatic Computer (EDVAC) and early files on the Uniprinter and Universal Automatic Computer (UNIVAC) include instruction codes, manuals, programming, reports, specifications, and training guides. The file on potential projects and contracts generally includes correspondence and sometimes includes proposals. It is frequently unclear when Eckert-Mauchly Computer Corporation

- Page 48 - John W. Mauchly papers Series III. Eckert-Mauchly partnership

actually received a contract. This subseries also documents the recognition John W. Mauchly, J. Presper Eckert, and EMCC received for their inventions and work, particularly in the press, and publicity associated with the above mentioned computers and the 1949 award of the Potts Medal to both Eckert and Mauchly.

Subseries C. Remington Rand/Sperry Rand records is further divided into: i. Company records, ii. Correspondence, iii. Patents, iv. Projects, v. Publicity, vi. Research and "Problems," vii. Research and writing by staff, and viii. Research on other computers and computer companies, and ix. Training. This subseries, housed in boxes 13 to 26, is large and complicated and is therefore described in further detail here.

Subseries D. Notes and datasheets shows many of Mauchly's interests and includes his notes, formulas, and math problems, as well as data gathered from other sources. Many of these interests were life-long, in particular Mauchly's interest in weather and forecasting; and therefore, researchers should consult the Notes and datasheets groupings in other series for earlier and later research on the same topics. In this subseries, the notes and datasheets are so extensive in relation to the weather, that they are grouped together under the term "weather-related."

Subseries E. Organizations, conferences, and memberships demonstrates that as Mauchly became more involved in his profession, and was considered an expert in the field of computers, he increasingly joined societies and attended conferences for his continuing education. Researchers will find that he continued to associate with some of these organizations throughout his career, and should, therefore, consult the subseries titled Organizations, memberships, and conferences in other series for earlier and later records. During this era of Mauchly's career, he was clearly a leader in the field--he served on committees, was asked to speak regularly, and was in communication with many others in business automation, computers, math and physics, programming, and other specialties.

Subseries F. Personal and family documents contains material that documents Mauchly's family and home life from 1946 to 1959. The bulk of these records are financial in nature, however Mauchly’s personality is apparent in letters to and from family and friends, information relating to his children's education, his poetry, prose, and humorous writings, hospital receipts from the births of three of his children, and a list of potential names for his newborn daughter. Sympathy letters sent to John, Jimmy, and Sidney Mauchly following the drowning of Mauchly's first wife Mary on September 8, 1946 are located in this subseries.

- Page 49 - John W. Mauchly papers A. Electronic Control Company (ECC)

Subseries G. Talks by Mauchly includes interviews, presentations, speeches, and talks. These talks are arranged chronologically. Whenever possible, the title of the speech, the organization to which Mauchly was speaking, the city, and the date are noted. Researchers should be aware that in some cases, Mauchly's speech does not actually exist, however, whenever that is the case, it isw noted in the folder title.

Subseries H. Teaching: "Mathematics for Digital Computers" at Temple University includes correspondence to and from Mauchly and Temple University, his plans for the course which Mauchly taught from 1953 to 1954, and his students’ work. Researchers should be aware that the student work and exams are restricted due to the Family Educational Rights and Privacy Act of 1974.

Subseries I. Writings by Mauchly, articles and other writings. This subseries is arranged chronologically. Some writings were published but Mauchly appears never to have intended publishing others. Many of Mauchly’s unpublished documents on topics of interest to him may have been written for his personal use and reference. When the information exists, researchers will find the title of the article, the title, volume and number of the publication in which it appeared, and the name of the co-author. Researchers should also consult the Office files in Series III. Eckert-Mauchly partnership, Subseries C. Remington Rand/Sperry Rand, i. Company records for other writings about Mauchly and his beliefs.

Subseries J. Writings by others, includes articles written by other scientists, physicists, and leaders in the field of computers. These writings are organized alphabetically by author and many do not appear to have been ready for publication. Instead, many of these seem to have been sent to Mauchly for review or because he was interested in the topic or author. These writings are not by staff members of ECC, EMCC, or Remington Rand; writings by staff are included in Subseries A., B. and C. within this series. These are also not the published writings by others which will be found in the later series, John W. Mauchly library, as yet unprocessed.

C. Remington Rand/Sperry Rand, 1950-1959. Scope and Contents note

The Remington Rand/Sperry Rand records are divided into: i. Company records, ii. Correspondence, iii. Patents, iv. Projects, v. Publicity, vi. Research and "Problems," vii. Research and writing by staff, viii. Research on other computers and computer companies, and ix. Training. This group of records documents a complicated time frame in Mauchly's work history, during which Eckert and Mauchly's positions and roles in the larger company are frequently difficult to ascertain. Of particular interest for researchers should be the information about the UNIVAC Applications Research Center (UARC) which Mauchly headed from 1955 to 1959. His campaign for such an applications research group began much earlier.

i. Company records, lists departments, divisions, and other groups created by Remington Rand/Sperry Rand. For the most part, this group of records houses memos to and from management, departments, and Remington Rand/Sperry Rand colleagues. Some of these documents are on steno disks or on printouts from steno disks. This group provides a glimpse into the complexity of this large company and its departments’ working relationships. Of particular interest are the office files, from which researchers can piece together Mauchly's day-to-day activities and most importantly, read his personal and confidential notes (box 14, folder 2), in which his core beliefs about the company, the future and needs of the computer industry and Remington Rand's place in the industry can be found. Similar material will be

- Page 55 - John W. Mauchly papers C. Remington Rand/Sperry Rand

found in other folders within Subseries C. Researchers should be aware that some personnel records (contained in box 15, folders 1 and 34) are restricted due to personally identifiable information. This group of material also documents the history of the UNIVAC Applications Research Center (UARC), a department which was headed by Mauchly. Almost like a company itself, the UARC appears to have been vitally important to Mauchly; his records of its operation are thorough and extensive.

ii. Correspondence, the second group of materials within Remington Rand/Sperry Rand records is largely professional correspondence, but does not contain intra-company memos (which are housed in the first group of records within this subseries). Correspondence is arranged alphabetically by correspondent (Mauchly's or his secretary's original order was maintained). In general, Mauchly's correspondence is not deep and frequently consists only of one or two letters per correspondent. Researchers will, however, find some prominent scientists among the correspondents.

iii. Patents contains correspondence regarding patent interference, but there are, in fact, several patents for Eckert and Mauchly inventions, including the Electronic Numerical Integrator and Calculator (ENIAC). There are also several guides to protecting inventions, particularly electronic computers, via patents.

iv. Projects, consists of Remington Rand's delivery of services to other organizations, including the U.S. military, retail organizations, churches, publishing companies, telephone companies and universities. One of the most notable projects was "Project 'Election Return'" in which the UNIVAC predicted the outcome of the presidential election in 1952. Materials in this group of records are arranged alphabetically by name of the organization hiring Remington Rand. Similar material will be found in the UNIVAC Application Research Center (UARC) files contained within i. Company records.

v. Publicity contains the extensive press and publicity about Eckert, Mauchly, the ENIAC and the UNIVAC. This group includes brochures published by Remington Rand, information regarding exhibits held at the Franklin Institute, and newspaper and magazine articles about the inventors and their inventions. Of interest is an article about Grace Hopper, an early programmer and inventor of the compiler, who was an employee of Remington Rand and a close colleague of John Mauchly.

vi. Research and "Problems," is a large group of materials in which topics needing investigation were attacked by Mauchly and his colleagues. In this case, and throughout Mauchly's papers, the term "problem" should be interpreted as a mathematical problem, rather than a business concern. Arranged alphabetically by topic, the material includes correspondence, manuals, minutes, notes, instructions, reports, and outside research, all of which appear to have served as the raw materials used by Mauchly

- Page 56 - John W. Mauchly papers C. Remington Rand/Sperry Rand

and his colleagues to develop coding, programming methodology, routines and subroutines, storage devices, etc. Researchers should pay close attention to the files on programming, which include seminal documents such as "What is Generalized Programming?" Much of this material is closely related to the UNIVAC Applications Research Center (UARC) files. Programs and products related to the UNIVAC System are arranged alphabetically under UNIVAC.

vii. Research and writing by staff is arranged alphabetically by staff member. Mauchly and his colleagues were pioneers in the fields of computer development and programming and wrote prolifically on topics related to their research and discoveries. Some of this writing does not appear to have been intended for publication--in some cases, it may have been meant only for in-house use to communicate progress and new ideas. Mauchly’s original arrangement of this material has been maintained as much as possible; researchers may therefore find copies of his colleagues’ articles filed in multiple locations within the collection including, almost always, under the topic of the article. Mauchly's own writings are found in Subseries I. Writings by Mauchly.

viii. Research on other computers and computer companies contains brochures, comparisons, notes, and writings about individual companies and specific computers. As the computer industry expanded, Mauchly and his colleagues kept a close eye on competitors’ companies and products. This group of material is arranged alphabetically by company name.

ix. Training contains computer training materials compiled by Mauchly for his engineers and other staff, including an extensive training course for EMCC engineers. There are also seminar courses for corporations and organizations using the UNIVAC as well as training courses for programming the UNIVAC.
