Alexander Graham Bell, geboren am 3. März 1847 in Edinburgh, Schottland und verstorben am 1. August 1922 in Baddeck, Kanada war ein britischer, später US-amerikanischer Audiologe, Erfinder, Großunternehmer und Befürworter der Eugenik. Es gelang ihm 1876, aufbauend auf Ideen seiner Vorgänger, das Telefon zur Marktreife zu entwickeln und ein flächendeckendes Telefonnetz in Nordamerika aufzubauen, das von seinem Unternehmen American Telephone and Telegraph Company monopolartig beherrscht wurde.
Davenport Car Manufactory plaque, on the facade of 710 Main Street, Cambridge, Massachusetts, USA. This building was home to the Davenport Car Manufactory, pioneering manufacturer of railroad cars, as noted in the plaque. According to another plaque below, it was subsequently one end of the first two-way long distance telephone conversation, which extended across three hours on October 9, 1876. Thomas G. Watson was at this location, and spoke to Alexander Graham Bell at 60 Kilby Street, Boston, Massachusetts.
Bell Alexander Alexander Graham Bell Signed School of Vocal Physiology Diploma Large diploma on vellum, 16.5" x 13.75". Partially printed document signed by Alexander Graham Bell in full signature as "Alexander Graham Bell", and dated "May 22, 1877". Diploma certificate for "Eva Ballard", who has "satisfactorily completed the prescribed course in this School and is hereby granted the privileges of a Graduate of the "School of Vocal Physiology". Lightly toned document with some fading to Bell's signature which appears to ever so lightly have been touched up. Matted to an overall size of 19.5" x 16.75". The area of vocal physiology covers the parts of the body involved in producing sound with the voice. Generally when we think of the voice we think of primarily the larynx. When he was 25, Bell opened his School of Vocal Physiology and Mechanics of Speech in Boston, MA, where he taught deaf people to speak. At age 26, although he did not have a university degree, he became Professor of Vocal Physiology and Elocution at the Boston University School of Oratory. Speech had become his life: his mother had gone deaf, and Bell’s father had developed a method of teaching deaf people to speak, which Bell also taught. His research into mechanizing human speech had become a relentless obsession. Alexander Graham Bell was one of the primary inventors of the telephone, did important work in communication for the deaf and held more than 18 patents, this fantastic document was signed by Bell in same year of founding the Bell Telephone Company in 1877, and in the same year as his marriage to Mable Hubbard, a former student and the daughter of Gardiner Hubbard, one of his early financial backers. Mable had been deaf since her early childhood years.

Boston: John Wilson & Son, 1877. 8vo. Disbound. FIRST EDITION OF BELL'S FIRST REPORT ON THE TELEPHONE. A LANDMARK WORK IN THE HISTORY OF TECHNOLOGY. This article concerning Alexander Graham Bell’s research on the telephone marks a pivotal moment in the history of technology and communication. Bell describes the first successful transmission of human speech via the telephone: “I placed the membrane of the telephone near my mouth, and uttered the sentence, ‘Do you understand what I say?’ Presently an answer was returned … and I heard the sentence: ‘Yes; I understand you perfectly.’” Bell conducted his work, and presented his findings in Boston. He received the first U.S. patent for the telephone in the same year. "In 1874, while experimenting with a tuned system of telegraphy, and also studying the path of sound waves in the human ear, Bell combined the two investigations and worked out the theory of the telephone... Bell succeeded only after long and discouraging experiment and he produced three telephones before he felt equal to a public demonstration in 1876. The first intelligible sentences exchanged over the telephone were transmitted from one room to another in the same house between Bell and assistant [Watson]. They were 'Do you understand what I say?' 'Yes; I understand you perfectly.' In the same month, March 1876, Bell took out his first patent which, although frequently and bitterly contested, was consistently upheld by the courts. In April 1877 Bell's system was installed between New York and Boston as the first public telephone service. His name is still commemorated in the nation-wide telephone service of the United States" (PMM 365). Dibner Heralds of Science 69; Norman 164; Origins of Cyberspace 116; PMM 365.
