This global business started in the leased space of one of the founders, John Dwan, which now houses the 3M Birthplace Museum. The original concept in 1902 was to mine corundum, a very hard crystallized mineral, and sell it to grinding wheel manufacturers out East. But the mineral turned out to be something softer and the business was sold in 1905 and moved to Duluth. Stop by the museum to find out what happened.
