The Early Years of the Acoustic Phonograph Its Developmental Origins and Fall from Favor 1877-1929
THE EARLY YEARS OF THE ACOUSTIC PHONOGRAPH ITS DEVELOPMENTAL ORIGINS AND FALL FROM FAVOR 1877-1929 by CARL R. MC QUEARY A SENIOR THESIS IN HISTORICAL AMERICAN TECHNOLOGIES Submitted to the General Studies Committee of the College of Arts and Sciences of Texas Tech University in Partial Fulfillment of the Requirements for the Degree of BACHELOR OF GENERAL STUDIES Approved Accepted Director of General Studies March, 1990 0^ Ac T 3> ^"^^ DEDICATION No. 2) This thesis would not have been possible without the love and support of my wife Laura, who has continued to love me even when I had phonograph parts scattered through out the house. Thanks also to my loving parents, who have always been there for me. The Early Years of the Acoustic Phonograph Its developmental origins and fall from favor 1877-1929 "Mary had a little lamb, its fleece was white as snov^. And everywhere that Mary went, the lamb was sure to go." With the recitation of a child's nursery rhyme, thirty-year- old Thomas Alva Edison ushered in a bright new age--the age of recorded sound. Edison's successful reproduction and recording of the human voice was the end result of countless hours of work on his part and represented the culmination of mankind's attempts, over thousands of years, to capture and reproduce the sounds and rhythms of his own vocal utterances as well as those of his environment. Although the industry that Edison spawned continues to this day, the phonograph is much changed, and little resembles the simple acoustical marvel that Edison created. -

He emigrated in 1884 to the United States, where he became a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company eventually marketed. -

The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice,keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic, or electric fields or the use of sound.

Chichester A. Bell. (Portion of written matter inside Package.—) We, Alexander Graham Bell; Sumner Tainter; and Chichester A. Bell, having associated ourselves together for the joint prosecution of inventions and experiments, desire to put on record a process and apparatus which we have devised for recording sound-vibrations, and for reproducing the sounds from the record, without deterioration of the record itself. Notes by Charles Sumner Tainter, October 23, 1881, with transcript http://www.loc.gov/resource/magbell.25100201 Library of Congress For some months previous to the present date (September 1881) our invention has been practically perfected, but we still withhold publication in the hope that our continued efforts may result in a more simple form of apparatus, adapted for popular use. The possibility of reproducing the sounds of articulate speech from a record was demonstrated several years ago by the construction of the Edison Phonograph, but 2 the articulation of the instrument was, at best, very imperfect and disagreeable; and the indented tinfoil record soon became deteriorated by use, so that the words impressed upon it ceased to be reproduced after a very few repetitions. -

A STUDY on PHOTOPHONES -..:: Ascent Journals
International J.of Multidispl.Research & Advcs. in Engg.(IJMRAE), ISSN 0975-7074, Vol. 2, No. III (October 2010), pp. 489-499 A STUDY ON PHOTOPHONES S. BASKARAN AND HARSH DEV Abstract Apart from limited military applications, optical telephony remained a relatively impractical form of communication from the invention of the photophone in 1880, to the development of semiconductor light sources and detectors in the 1960s. While optical fibres have become a major component of modern telecommunications, and infra-red remote controls are incorporated in many domestic appliances, optical communication has been largely ignored by radio amateurs. Construction projects for photophones have been published from time to time over the last 60 years, but there have been few reviews of optical communication and its potential as a medium for amateur voice and data communication. This article is a mixture of history, theory and personal experience, written with the intention of introducing optical communication to the general body of radio amateurs and possibly stimulating further experimentation in the oldest branch of wireless The invention of the selenium cell in 1872 and the telephone in 1876, made it possible to detect modulated light, and Mr A.C. Brown of London is generally credited with the first transmission of articulate speech over a light beam in 1878. Much of the pioneer work in optical telephony was carried out by Alexander Graham Bell and Charles Sumner Tainter during 1879 and 1880, which was presented in a paper 1, read by Bell to the American Association for the Advancement of Science in August 1880. The Bell photophone (Figure 1) used a flexible plane mirror mounted at the end of a speaking tube, so that the sound pressure caused the mirror to change shape, modulating the beam intensity of the reflected light. -

RAYMOND R. WILE Cylinder Record Materials Although record collecting may be traced back to the turn of the century, there has been little in the way of serious study devoted to the problems ofpreservation. The 1959 Pickett and Lemcoe study for the Library of Congress1 identified some of the problems of shellac and vinyl records but ignored completely those of cylinders and most other vertical-cut recordings. As far as I know, an unpublished paper that I delivered before the New York Chapter of the Music Library Association in 1978 was unique in raising questions; it was greeted with an almost audible "ho hum".2 Since the date of that paper, more years have lapsed and further degradation of stored cylinders has undoubtedly taken place. The notes to follow are offered in the hope that, by examining the historical evidence, steps may be taken to redress past omissions. Tinfoil Recordings he most difficult period to document in terms of surviving recordings is the first - Tthe tinfoil period. In many cases, the tinfoil was attached to the phonograph mandrel by means of shellac. The removal of a foil that had been so affixed was virtually certain to assure its destruction. A later form of phonograph developed by Edison used a clamping bar to temporar ily secure the foil in an axial slot in the mandrel. While this bar held the foil securely, it also caused a dead spot in the recording and added the difficulty of groove align ment, should one wish to reattach a previously recorded foil. Few tinfoil recordings have survived and I know of none that have been success fully reproduced. -
For Whom the Bell Tolls
As Seen In Feb. 4-10, 2005 For whom the bells toll By KEN SCHACHTER When Anthony Leteri started indus- trial coating company USA Polycoat Inc. in 1981, life was simple. Americans could use any phone serv- ice they wanted – as long as it was AT&T. The same held true for service, equipment and listings in the Yellow Pages. That was almost a quarter century and, for USA Polycoat, about six phone companies ago. “You had one call to make when your phone broke,” Leteri said. “Those were the good times, I guess.” Nostalgia notwithstanding, analysts say, the old Ma Bell is dead.

Bill Klinger; Association for Recorded Sound Collections
CYLINDER RECORDS: Significance, Production, and Survival Bill Klinger Association for Recorded Sound Collections This document is a response to requests for comments and data that might help to inform the National Recorded Sound Preservation Study. It describes the significance of cylinder phonograph records and offers quantitative estimates regarding their production and survival. 1 Respondent’s Background and Affiliation I write partly as a private record collector and partly as a representative of the Association for Recorded Sound Collections (ARSC). ARSC is a nonprofit organization, founded in 1966, dedicated to the preservation and study of sound recordings—in all genres of music and speech, in all formats, and from all periods. ARSC is unique in bringing together private collectors, historians, discographers, engineers, and institutional professionals, including representatives of some of the world’s largest libraries and archives. I chair the Cylinder Subcommittee of the ARSC Technical Committee, which developed the ARSC Guidelines for Cylinder Playback Equipment (funded by grants from the National Academy of Recording Arts & Sciences). I am a Founding Member of the National Recording Preservation Board, representing ARSC. For more than thirty years, I have researched the history, technology, and products of the cylinder record industry. My personal collection currently includes 7,277 cylinder records, of nearly all types and brands. 2 Significance of Cylinder Records Mechanical sound-carriers configured in cylindrical form represent an important part of our recorded- sound heritage, for many reasons: 2.1 World’s Oldest Format for Sound Recording and Playback Thomas Edison’s tinfoil phonograph of 1877—which employed a thin sheet of metal foil, formed into a cylinder—was the first device to successfully “capture” and reproduce sound.
