Native Americans mined copper in and around what would later be Houghton thousands of years before European settlement. "French explorers had noted... [its] existence [in the area] as early as the seventeenth century, [and in] 1772 Alexander Henry had prospected for copper on the Ontonagon River near Victoria."
Many Cornish and Finnish immigrants arrived in the Houghton area to work in the copper mines in the mining boom that made Copper Country on the Keweenaw Peninsula; both groups have had a great influence on the culture and cuisine of the local area. The Finns and others called much of the area Copper Island. Smaller numbers of French-Canadian immigrants moved to Houghton, while more of them settled elsewhere in Houghton County.
