Jacob Schick

Born 16 Sep 1877; died 3 Jul 1937 at age 59.American inventor and manufacturer of the first successful electric dry razor. He started in the razor business in 1925 to design and manufacture his invention of the Magazine Repeating Razor. By 1926, he was selling clips of blades that could be loaded into a safety razor without touching the blade to avoid cuts during handling. While this product was successful, he turned his attention to developing a dry razor. By 1927 he had designed a dry razor with a reciprocating head powered by a flexible drive shaft to an external motor. Although he marketed this model from 1929, it was not until 1931 that he had improved the idea as a new one-handed electric shaver with self-contained motor that sales took off. He lived only six year after that.«.
