On October 8, 1940, David C. Rockola received U.S. Patent No. D122,946 on a Cabinet for Remote Control Apparatus:

This was not the first patent by this prolific inventor, that was U.S. Patent No. USD81021 that issued more than ten years earlier in 1930, and it was far from the last, that was U.S. Patent No. US 3771691 that issued more than thirty years later in 1973.

David Rockola invented everything from gaming devices, to parking meters, to vehicles, to juke boxes — what his is probably best know for.

It turns out that ROCKOLA was not just a snappy name for juke boxes, but it a snappy name for a prolific inventor who did far more than juke boxes.
