Noah Armstrong

Noah Armstrong (January 18, 1823 – April 21, 1907) was a superintendent of the Glendale smelter and discoverer of the Hecla Mine in western Montana. Later in life he moved to Seattle, where he established the Seattle Transfer Company.

Armstrong was also an avid horse breeder. He owned and bred Spokane, the winner of the 1889 Kentucky Derby. Spokane is the only horse foaled and trained in Montana to ever win the Kentucky Derby, doing it the same year Montana was admitted to the Union. Armstrong's ranch was Doncaster Ranch, near Twin Bridges, Montana, which includes the Doncaster Round Barn. Built in 1882, it is a structure listed on the National Register of Historic Places and the birthplace of Spokane in 1886.
