Organized in 1845, Houghton County once comprised the entire Keweenaw Peninsula. Eagle River was the first county seat. In 1861, after the state legislature split the county into Keweenaw and Houghton, the village of Houghton became the new seat of Houghton County government. Finnish settlers were predominant in the county. There were also Scandinavians, as well as Cornish, Germans and French Canadians. Jobs were plentiful, since Houghton County was the center of the copper boom. In 1874, Michigan produced 88 percent of the nations' copper, of which Houghton county mines supplied 79 percent. Two years later, Michigan copper production peaked at 90 percent of the nation's output. The Michigan Mining School opened in Houghton in 1886. In 1964 it was renamed Michigan Technological University.
