Celebrity Inventors: Zeppo Marx

Zeppo Marx, the youngest of the family, tended to play the ‘straight man’ in the brothers’ films. He was also, in his time, the holder of two patents. The first was a coupling device for World War II bombers. In 1945, it was used to release the atom bombs over Hiroshima and Nagasaki.

Twenty four years later, Zeppo patented an altogether nicer invention, a wristwatch heart monitor, together with Albert D Herman.
