Massachusetts Institute of Technology. News Office (AC0069) From the Office of Public Relations Massachusetts Institute of Technology Cambridge, Massachusetta 0213c Telephone: UN 4-6900, Ext. 2701-5 FOR IMMEDIATE RELEASE Dr. John Clarke Slater, Institute Professor at the Massachusetts Institute of Tech- nology and one of the world's leading solid state physicists, will retire effective July 1 after 36 years of teaching and research at M.I.T. Dr. Slater for the past several years has been dividing his time between M.I.T. and the University of Florida at Gainesville where he holds appointment as Graduate Research Professor of Physics. Following official retirement with the title of Institute Professor Emeritus, Dr. Slater plans to continue both associations. Always at the forefront of major scientific advances of his time, Dr. Slater as a young scientist studied with the great physicists Werner Heisenberg and Niels Bohr and over the years has been closely associated with the development of quantum theory and modern physics. In his research, Dr. Slater made such fundamental contributions to the science underlying the transistor that Dr. Mervin J. Kelly, former president of Bell Telephone Labora- tories, was to say of him: "As organizer of the basic research program in semiconductors at Bell Laboratories that led to the monumental invention of the transistor, may I say that had it not been )or the prior work of M.I.T.'s Professor John C. Slater and a few other academi- cians in solid state physics, the team of scientists at Bell Laboratories could not have made the transistor invention." Dr. Slater came to M.I.T. as Head of the Department of Physics in 1930, the same year that the late Dr. Karl T. Compton became President. It was at this time, under Presi- dent Compton, that the Institute began a major move to expand and strengthen its work in -more- Use copy created from Institute Archives record copy. © Massachusetts Institute of Technology MIT Institute Archives & Special Collections.

During World War II, Dr. Slater made important contributions to radar development at the M.I.T. Radiation Laboratory. His investigations early in the war led to a general under- standing of the theory underlying the operation of the magnetron oscillator and the transmis- sion of microwaves- -an uaderstanding that greatly increased the effectiveness of radar and magnetron efficiency. One result was the emergence of so-called x- band radar that made air-borne blind bombing possible. Dr. Slater's wartime book, "Microwave Transmission" (1942), set forth the principles of microwaves primarily for the benefit of those then working on radar, but it continues to stand as a standard work in the field. Following the war, Dr. Slater was a prime mover in the establishment of both the Research Laboratory of Electronics and the Laboratory for Nuclear Science, both of which pioneered in new patterns of interdepartmental university research. He drafted and proposed the original plans under which the Basic Research Division of the Radiation Laboratory, then beirn- nclosed down, was transformed into the Research Laboratory of Electronics and there- by retain intact the vast store of basic data, knowledge and equipment built up through the wartime radar effort. Much of modern electronics has grown from the wartime work that was thus preserved. In 1951, Dr. Slater was promoted from department head to be M. I.T. 's first Insti- tute Professor shortly after the post was created to recognize outstanding individuals whose contributions have had broad effect throughout science and technology. He also was appointed that year the Henry B. Higgins Professor of the Solid State (Physics) under a grant from the Pittsburgh Plate Glass Co. He spent the academic year 1951-52 on leave as a staff member -more- Use copy created from Institute Archives record copy. © Massachusetts Institute of Technology MIT Institute Archives & Special Collections.

Solid State and Molecular Theory Group concerned with applying modern theoretical methods, including wave mechanics and the use of digital computers, to the theory of atoms, molecules and solids. As an associated activity, Dr. Slater guided the development of plans for the Insti- tute's new interdisciplinary Center for Materials Science and Engineering for the study of materials in the modern sense. This view includes traditional ideas of materials--such as- metals, concrete or textiles--for structural or other uses, but it also embraces studies of unusual metals and alloys, single crystals, ceramics and compounds that have electrical, magnetic and other properties. The Center was established in 1961 and just last year moved into its new $6, 000, 000 Vannevar Bush Building. Professor Slater was born in Oak Park, Ill., in 1900, and four years later the family moved to Rochester, N.Y., where his father joined the staff of the University of Rochester, later becoming professor and head of the Department of English for 34 years. His father, Dr. John R. Slater, died last year at 93. Two years ago the University of Rochester presented both the father and the son with honorary degrees at the same commencement. M.I.T.'s Professor Slater was graduated from Rochester in 1920, then entered the Harvard University graduate school, receiving the degrees of master of arts and doctor of philosophy in 1922 and 1923 respectively. As a Sheldon traveling fellow from Harvard, he studied overseas for a year, spending six months at Cambridge, England, and the other half year working with Bohr in Copenhagen, Denmark. He returned to Harvard as an instructor in physics. From that time until his appoint- ment at M.1.T. in 1930, Professor Slater supplemented his teaching with considerable research, particularly in the quantum theory. During the summer of 1926 he taught at Stanford Univer- -more- Use copy created from Institute Archives record copy. © Massachusetts Institute of Technology MIT Institute Archives & Special Collections.

From June, 1929, to February of the following year he studied abroad as a fellow of the Guggenheim Foundation, working first in Zurich, Switzerland, and later on in Leipzig, Germany, with Heisenberg and the physicist Friedrich Hund. Professor Slater has contributed numerous technical articles to scientific journals and is the author of "Introduction to Chemical Physics" (1939), "Microwave Electronics" (19- 49), "Quantum Theory of Matter" (1951), "Modern Physics" (1955), the two-volume "Quantum Theory of Atomic Structure" (1960), and the three- volume " Quantum Theory of Molecules and Solids (1963-66). He is co-author with N .H. Frank of "Introduction of Theoretical Physics" (1933), "Mechanics" (1947), and "Electromagnetism" (1947). He is a member of the American Academy of Arts and Sciences, National Academy of Sciences, American Philosophical Society, American Physical Society, Phi Beta Kappa, and Delta Upsilon. -end- June 30, 1966 Use copy created from Institute Archives record copy. © Massachusetts Institute of Technology .

  • Inventing the Endless Frontier: the Effects of the World War II Research
    Inventing the Endless Frontier: The Effects of the World War II Research Effort on Post-war Innovation∗ Daniel P. Gross† Bhaven N. Sampat‡ Harvard Business School and NBER Columbia University and NBER June 2, 2020 first draft: June 2, 2020 Abstract: During World War II, the U.S. government launched an unprecedented effort to mobi- lize science for war: the newly-established Office of Scientific Research and Development (OSRD) entered thousands of R&D contracts with industrial and academic contractors, spending one to two orders of magnitude more than what the government was previously investing in science. In this pa- per, we study the long-run effects of the OSRD-supported research effort on U.S. invention. Using data on all OSRD contracts, we show that these investments had large effects on the direction and location of U.S. invention and high-tech industrial employment, setting in motion agglomeration forces which shaped the technology clusters of the postwar era. Our results demonstrate the effects of a large, mission-driven government R&D program on the growth of domestic technology clusters and long-run technological progress.

    • DELANEY AND WARD Radar Development at Lincoln Laboratory: An Overview of the First Fifty Years Radar Development at Lincoln Laboratory: An Overview of the First Fifty Years William P. Delaney and William W. Ward I This article provides an overview of the first fifty years of radar development at Lincoln Laboratory. It begins by reviewing early Laboratory efforts in North American air defense, which quickly branched into efforts in missile defense and space surveillance as the Soviet Union developed missiles and launched satellites into space. In the 1970s, two other radar-intensive activities began at the Laboratory: a program in tactical surveillance arose out of the challenges of the Vietnam War, and a program in air traffic control responded to the need to modernize systems for control of civilian aircraft. Research in advanced air defense also returned to the Laboratory with the advent of the modern cruise missile. This article summarizes these major Laboratory radar programs in a synoptic fashion, which can serve the reader as a road map to the ensuing fourteen articles, each of which provides a more in-depth view of the Laboratory’s radar developments. - Laboratory directly involve radar development, tech- ogy has been involved in radar development nology, or experimentation.

Any opinions expressed in this memoir are those of the authors and do not necessarily reflect the views of the National Academy of Sciences. BENJAMIN LAX December 29, 1915–April 21, 2015 Elected to the NAS, 1969 Benjamin Lax made significant and lasting contributions to solid-state physics and engineering. He innovated new resonance phenomena, including cyclotron reso- nance, to determine the basic band structure of semi- conductors. He pioneered the field of magneto-optics and made important theoretical contributions that led to the demonstration of the first semiconductor GaAs diode laser. His seminal basic and applied research on semicon- ductor physics and engineering, which included solid- state plasmas and quantum electronics, provided a foun- dation for the development of semiconductor technology. The locus of Ben’s sixty-year career was the Massachu- setts Institute of Technology (MIT). His career began By Roshan L. Aggarwal1 during World War II at the MIT Radiation Laboratory on and Marion B. Reine2 the MIT campus in Cambridge, Massachusetts. After the war, in 1951, he joined the recently formed MIT Lincoln Laboratory in Lexington, Massachusetts, where in 1958 he became the head of the Solid State Division and in 1964 the associate director of the Lincoln Laboratory. He champi- oned and secured funding for the Francis Bitter National Magnet Laboratory located on the MIT campus, and in 1960 he became the founding director of that laboratory. In 1965, he became a professor in the MIT Department of Physics, where he supervised thirty-six MIT doctoral students over a thirty-year period.

  • Under the Radar
    Under the Radar Physics, Engineering, and the Distortion of a World War Two Legacy A thesis presented by Raphael Chayim Rosen to The Department of the History of Science in partial fulfillment for an honors degree in History and Science Harvard University Cambridge, Massachusetts March 2006 Under the Radar Physics, Engineering, and the Distortion of a World War Two Legacy Raphael Chayim Rosen Abstract This thesis examines the historical legacy of microwave radar development during World War II. At the M.I.T. Radiation Laboratory in 1940-1941, physicists attempted to construct a working microwave radar set. These physicists heavily relied upon engineering skills: focusing on enhancing the efficiency and efficacy of specific components of radar technology. In the postwar era, as a result of the new celebrity of physicists, their wartime inventions, including microwave radar, became associated with physics itself, not engineering. The community of engineers lacked the authority and recognition necessary to reclaim a share of the credit for their discipline. Physicists never emphasized engineering’s importance, because they did not see it as containing independent forms of knowledge or creativity and so did not believe it had played a key role in their inventiveness. This thesis concludes with a brief investigation of engineering’s endogenous forms of knowledge and their relation to the Radiation Laboratory. Keywords M.I.T.
