Rezin Pleasant Bowie (September 8, 1793 – January 17, 1841) was an American inventor and designer of the Bowie knife. He also served three terms in the Louisiana Legislature.With his brother James, Bowie smuggled slaves and worked as a land speculator. The brothers set up the first steam mill in Louisiana to be used for grinding sugar cane. Bowie took credit for inventing the Bowie knife, which came to prominence when used by James in the Sandbar Fight in 1827. After James Bowie moved to Texas, Bowie accompanied him on an expedition to find the Lost San Saba Mine. They did not find the mine, but their adventures in fending off a much larger Indian raiding party became widely known.In his later years Bowie suffered from poor eyesight. He lived with his wife and daughters on a plantation in Louisiana.
