Shown here is Newton D. “Jack” Baker, III, the son of U.S. Secretary of War Newton D. Baker.

The picture appeared a hundred years ago this month in the November 1920 issue of Radio News, which reported that he had studied radio telegraphy enthusiastically, and had mounted this portable set on his bicycle, on which he listened while riding around Washington. With just the frame of the bike as an antenna, he was able to pick up NAA Arlington.

If Master Baker and his radio look familiar, that’s because we’ve seen both of them previously. He had been an exceedingly good boy during 1919, and Santa Claus brought the radio as a reward, as shown in this close-up from the picture we previously shared. This photograph is clearly the same boy, the same radio, and even the same headphones as the Christmas photo.

I don’t see any record of Baker having received an amateur license, but it appears that he was an enthusiastic listener in the earliest days of radio.
