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.Minor chipping to edges.
