Editing Two Harbors, Minnesota (section)

====3M====
[[3M]], originally known as Minnesota Mining and Manufacturing Company, was started by five men from Two Harbors. When the founders thought they had found mineral called [[corundum]], which could be used to make sandpaper, they began setting up a mining company. The five were Henry S. Bryan, J. Danley Budd, Herman Cable, William McGonagle, and John Dwan. To get the company started they erected a large dock, crushing mill and bunk and storage houses. After selling the corundum to a company in Chicago the men learned that it wasn't really corundum and moved on to other ventures. In 1905 the company was moved to Duluth and in 1907 to St. Paul. It still had ties in Two Harbors until Dwan's death. Now the only tie 3M has to Two Harbors is a museum in [[John Dwan Office Building|Dwan's original office]]. The museum is in 3M's original building. Exhibits include Dwan's recreated office and other artifacts; a history of the company including photos and documents; a "lab" area representing the establishment of research and development, product diversification and growth; and hands-on interactive programs and technology applications. The original office building has been restored and is listed on the [[National Register of Historic Places]].
