3M Museum

The Dwan Office Building, first home of Minnesota Mining and Manufacturing. Now home to the 3M Museum.

This museum pays tribute to the birthplace of 3M in Two Harbors and the growth of a well-respected corporation. The five businessmen who founded 3M signed the articles of incorporation in this building in 1902. The Lake County Historical Society in 1991 purchased the Dwan Building. A year later it was listed on the National Register of Historic Places and opened as a museum depicting 3M’s early years.

In 1999, the Society received a grant from 3M to renovate the existing museum. The museum has been completely renovated to reflect the company’s success.

The museum continues to be maintianed through the generousity of 3M’s Community Affairs Foundation with an annual operating grant.

3M Video Tour

This tour is very special to us at the Society as we lost Eldon Platcek, the tour guide, shortly after this was shot. Eldon loved working the 3M Museum for us and he is missed.
Our gratitude to the gentleman that shot this video and for posting it on You Tube.
