Case File Catalog Summary
John J. Carty was a trailblazer of American telephony. He was awarded the Franklin Medal in 1916 for his involvement in the development of the telephone. Carty made early contributions to large-scale switchboard technology and in describing and eliminating the phenomenon of "cross talk," a kind of interference that plagued early telephone users. The first American transcontinental conversation took place under Carty's leadership as chief engineer of AT&T, as did the first wireless, transoceanic broadcast of the human voice.
The John J. Carty presentation was made possible by support from The Barra Foundation and Unisys.
