History
Founded in 1932 in Chicago by Arthur J. Schmitt as American Phenolic Corp., initially producing tube sockets for radios, Amphenol expanded during World War II as a primary supplier of military connectors for airplanes and radios.12 It underwent mergers including with Bunker-Ramo in 1967 and later Allied Chemical, before being acquired by LPL Investment Group in 1986 and refocusing on interconnect products.1 Key innovations include the BNC connector and MIL-DTL-38999 cylindrical connector from its Amphenol Aerospace division in Sidney, New York.2
