Bozak joined C.G. Conn in 1944 to help them develop an electronic organ. While in Elkhart, Indiana, he noticed that the human sense of hearing was unpredictable at best. Years later, Bozak recounted this story about the Conn electronic organ project: "The general sales manager, who was a pianist and played organ, sat down and played the thing and said it was great, just what we were looking for. A week later he was invited back into the laboratory and sat down and played the instrument again. He didn’t play ten or fifteen bars when he said, This goddamn thing doesn’t sound right. What did you guys do to it?’ We said we hadn’t done anything. Well, he didn’t believe us. ‘You did something to it. You messed it up here,’ he said. ‘Restore it back to the way you had it.’ So what we did was let the damn instrument sit there for another week, and he comes back and plays it again. ‘Now this is the way it should be,’ he says."
