Case File Catalog Summary

John J. Carty was a trailblazer of American telephony. He was awarded the Franklin Medal in 1916 for his contributions to the telephone art. Carty made early contributions to large-scale switchboard technology and to 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.
