Perhaps the most famous inventor that you've never heard of, 80-year-old Dr. Nakamats is the brilliant and eccentric holder of the world record in patents—3,300 and counting. A cult figure in Japan, Dr. Nakamats is credited for the creation of the floppy disk and the first digital watch, as well as for his flying "PyonPyon" shoes and "Love Jet" spray to heighten sexual stimulation, among, well, 3,296 others. Dr. Nakamats was awarded the Ig Nobel prize for Nutrition for photographing and retrospectively analyzing every meal he has consumed during a period of 34 years. By the time he dies at the age of 144 (a goal he pursues with an elaborate daily ritual), he intends to patent 6,000 inventions.
