In the early 1950s, Sidney Harman was the general manager of the David Bogen Company, a leading manufacturer of public address systems at the time, while Bernard Kardon was the chief engineer for the same company. Due to management changes at Bogen in the early 1950s, both men resigned, and with $5,000 investment from each, formed the Harman Kardon Company in 1953.
