Landmark event in the creation of the telephone...

Item # 589002

November 25, 1876

SCIENTIFIC AMERICAN SUPPLEMENT, New York, November 25, 1876 This was a separate, stand-alone publication initially created to report on the Centennial Exposition in 1876 but which lasted through the 20th century, and not a supplemental issue to the more famous "Scientific American".

Inside has an article: "Telephony" "Audible Speech By Telegraph" which reports on the very first telephone conversation using outdoor wires. It begins: "The following interesting account of an experiment made on the evening of October 9 by Prof. Alexander Graham Bell and Thomas A. Watson...Telephones were placed at either end of a telegraph line...extending from their office in Boston to their factory in Cambridgeport at a distance of about two miles...The sounds, at first faint & indistinct, became suddenly quite loud and intelligible..." with more including the verbatim conversation between the two.

This issue also has coverage on the Brooklyn bridge, including several illustrations.

Complete in 16 pages and in very nice condition.
