The Theo. Bergmann Shoe Manufacturing Co. was founded in Portland, Oregon in 1904 and went out of business in 1957. 

Theodore Bergmann, the founder, born in Rötha, Germany in 1856, learned the shoemaking trade there and immigrated to the United States in 1882 at the age of 37. Initially residing in St. Louis, he moved to Portland in 1893 where he started the eponymous shoe manufacturing company in 1904, principally making outdoor footwear for hikers, explorers, and lumbermen. 

They had 11 shoe types including the Bergmann Logger, with heights from 8 to 17 inches and priced from $8.50 to $11.50. The shoes were sold by traveling salesmen, who mostly combed the small towns of Oregon, Washington, Idaho, Montana, Northern California, Colorado, Nevada, and Alaska. 

Later Bergmann became the chosen manufacture for the now famous USMC 'Raider' boot.
