Thomas Fitzpatrick (1799 - 7 February 1854), known as Broken Hand (reportedly because his left hand had been mangled in a firearms accident), was a famous Irish-American mountain man, friend of the Indians, trailblazer and trapper with the Rocky Mountain Fur Company. With Jedediah Smith, he led a trapper band that discovered South Pass, Wyoming; however, before that Robert Stuart led the first known white party through the South Pass.
