A pioneer announcer and program manager who has been associated with New York broadcasting for many years recalls an incident about Thomas A. Edison. At the time, in 1921, he was doing the talking, such as there was, over WJZ, first New York area station.

One day, when we were thoroughly tired of talking endlessly into this telephone microphone, I got an idea. So I went up to see my old boss, Thomas A. Edison. It was a Friday, the last day of September, 1921. I thought we should try to get something that would make continuous sound, like a phonograph. Mr. Edison cooperated; he sent me a phonograph and some records—I didn’t buy them. We hoisted the phonograph onto the roof where we had the WJZ transmitter—it was too big to go through the hatchway —and carried the records up into the radio shack.

Mr. Edison had a sign on his laboratory door—“I Will Not Talk Radio to Anyone.” He always felt a little bit chagrined, I think, that De Forest beat him to the invention of the grid. The Edison effect was there and all De Forest did was to take the Edison effect and make it talk. It had other features of transmission up to that time but not speech. The grid was merely inserted there and that made the telephone feature of the tube.

Mr. Edison loaned me the phonograph and let me pick out some very good records. I remember one particularly, of Anna Case singing “Annie Laurie.” It was one of those big, thick Edison disks. But then one day he called up and asked us abruptly to discontinue the use of the phonograph, because he said he had listened and he didn’t think it did the phonograph business any good. We had the problem of modulation and lacked good technical resources.

He said, “If the phonograph sounded like that in any room, nobody would ever buy it.” We got around that problem by buying a phonograph of our own. But I did go up to see if there was any way by which we could continue the cooperation. He said no. He said that we weren’t ready to broadcast yet-that we had gone ahead without working out the involved features of broadcasting.

“Why do you give people a laboratory experiment? I give the public a finished product, and you’re a long way from having one. I don’t want any part of it; just count me out.”

I asked, “What is the great difficulty that you find? The interest is tremendous.”

Then, to explain how music could be broadcast better, he drew a circuit of the sound wave from the time it first impressed the telephone mouthpiece, went through the circuits and tubes and vibrated the diaphragm in the receiving headpiece. He figured it all out with resistances and everything. A great deal of it was beyond me technically,
