Lee de Forest
KZY was the successor to Experimental station 6XC, which dated to mid-1920, and which founder Lee de Forest suggested deserved credit as the "first radio-telephone station devoted solely" to broadcasting to the public. Including its predecessor, KZY's broadcasting history predated that of many better-known pioneer stations, including WWJ in Detroit, Michigan (started August 1920, originally as 8MK) and KDKA in Pittsburgh, Pennsylvania (debuted November 2, 1920 as 8ZZ).
