15 devices invented by celebrities

1. Drumhead Tensioning Device and Method

Invented by: Marlon Brando

Marlon Brando, of "The Godfather" fame, is considered one of the greatest actors of all time, but did you know he also was a percussionist and an accomplished inventor? In 2002, the "On the Waterfront" actor invented and patented an apparatus and method that simplified the surprisingly difficult and complex task of tightening a loose drum.

Brando doesn't stand alone, though, because these moms have created inventions and businesses of their own.

2. Artificial Heart

Invented by: Paul Winchell

Grammy-winning television pioneer Paul Winchell, who died in 2005, had a show business career that dated to vaudeville — but the ventriloquist and comedian also was an avid inventor with dozens of patents. One of them was the original artificial heart, which he patented in 1963. It was a prototype of the first artificial heart that was implanted into a human nearly 20 years later, according to The Washington Post.
