International Telephone and Telegraph Corporation
Incorporated in 1920 by Sosthenes Behn and his brother Hernand Behn as a telephone and telegraph company, ITT expanded and established facilities both in the United States and throughout the world. The firm was based Clifton, New Jersey.
The Fort Wayne, Indiana facility resulted when Philo T. Farnsworth, the inventor of electronic television, who had set up the Farnsworth Television and Radio Corporation, sold his company to ITT in 1949. The laboratories in Fort Wayne were responsible for developing new technical concepts, methods and designs of tubes, sensors and devices for application in industrial, government and commercial markets.
In 1951, ITT acquired the Kellogg Switchboard & Supply Company and branded it ITT Kellogg.
Global headquarters in the 1960s was in White Plains.
An Electron Tube Division was in Easton, Pennsylvania.
