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. -

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.

Letter from Alexander Graham Bell to Alexander Melville Bell, February 26, 1880, with Transcript
Library of Congress Letter from Alexander Graham Bell to Alexander Melville Bell, February 26, 1880, with transcript ALEXANDER GRAHAM BELL TO HIS FATHER A. MELVILLE BELL 904 14th Street, N. W., Washington, D. C. Feb. 26th, 1880. Dear Papa: I have just written to Mamma about Mabel's baby and I now write to you about my own! Only think! — Two babies in one week! The first born at 904 14th Street — on the fifteenth inst., the other at my laboratory on the nineteenth. Both strong vigorous healthy young things and both destined I trust to grow into something great in the future. Mabel's baby was light enough at birth but mine was LIGHT ITSELF! Mabel's baby screamed inarticulately but mine spoke with distinct enunciation from the first. I have heard articulate speech produced by sunlight! I have heard a ray of the sun laugh and cough and sing! The dream of the past year has become a reality — the “ Photophone ” is an accomplished fact. I am not prepared at present to go into particulars and can only say that with Mr. Tainter's assistance I have succeeded in preparing crystalline selenium of so low a resistance and so sensitive to light that we have been enabled to perceive variations of light as sounds in the telephone. In this way I have been able to hear a shadow, and I have even perceived by ear the passage of a cloud across the sun's disk. Can Imagination picture what the future of this invention is to be! I dream of so many important and wonderful applications that I cannot bring myself to make known my discovery — until I have demonstrated the practicability of some of these schemes. -

ARSC Journal, Vol
EDISON AND GROWING HOSTILITIES1 By Raymond Wile The spring of 1878 witnessed a flurry of phonographic activity at the Edison laboratories. Caveats were filed with the United States Patent Office, and Prelimi nary Specifications were filed on April 24, 1878 which resulted in the eventual issuance of a British patent.2 Despite this initial activity, the Edison involvement rapidly wound down by the end of that summer. In September a fatal mistake occurred-final specifications were supplied for the British patent, but the equiva lent American applications were neglected. In December, an attempt was made to rectify the omission by predating a series of applications, but the U.S. Patent Office refused to allow this and the matter had to be dropped. Except for a patent applied for on March 29, 1879 and granted in 1880 the phonograph seems to have been completely abandoned by Edison in favor of his new interest in the electric light.3 During the first half of the eighties there is no evidence whatsoever of any phono graph activity emanating from Menlo Park. However, Edward H. Johnson, who had done much experimenting for the Edison Speaking Phonograph Company, did be come involved in some experimenting after his return from England in 1883-enough so for Bergmann and Company to bill the group for 192 1/2 hours of experimental work.4 Edison had become completely disenchanted and reasoned that the concept of the phonograph was incapable offurther developments. The members of the Edison Speak ing Phonograph Company were delighted to relieve Edison of the responsibility for further experimenting when he released them from the necessity of investing further capital. -

Alexander Graham Bell 1847-1922
NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA BIOGRAPHICAL MEMOIRS VOLUME XXIII FIRST MEMOIR BIOGRAPHICAL MEMOIR OF ALEXANDER GRAHAM BELL 1847-1922 BY HAROLD S. OSBORNE PRESENTED TO THE ACADEMY AT THE ANNUAL MEETING, 1943 It was the intention that this Biographical Memoir would be written jointly by the present author and the late Dr. Bancroft Gherardi. The scope of the memoir and plan of work were laid out in cooperation with him, but Dr. Gherardi's untimely death prevented the proposed collaboration in writing the text. The author expresses his appreciation also of the help of members of the Bell family, particularly Dr. Gilbert Grosvenor, and of Mr. R. T. Barrett and Mr. A. M. Dowling of the American Telephone & Telegraph Company staff. The courtesy of these gentlemen has included, in addition to other help, making available to the author historic documents relating to the life of Alexander Graham Bell in the files of the National Geographic Society and in the Historical Museum of the American Telephone and Telegraph Company. ALEXANDER GRAHAM BELL 1847-1922 BY HAROLD S. OSBORNE Alexander Graham Bell—teacher, scientist, inventor, gentle- man—was one whose life was devoted to the benefit of mankind with unusual success. Known throughout the world as the inventor of the telephone, he made also other inventions and scientific discoveries of first importance, greatly advanced the methods and practices for teaching the deaf and came to be admired and loved throughout the world for his accuracy of thought and expression, his rigid code of honor, punctilious courtesy, and unfailing generosity in helping others. -
