The Dwan Office Building, birthplace of Minnesota Mining and Manufacturing, 3M – Mel Sando

The 3M Museum in Two Harbors is located in the original Dwan Law Office Building. The Lake County Historical Society purchased the Dwan Building in 1991. A year later it was listed on the National Register of Historic Places and opened as a museum depicting 3M’s early years. Completely redesigned in 2002 by the 3M Company and operated in partnership with the Lake County Historical Society the museum pays homage to the early days of the company that would go on to define the business model of research and development and become a global force employing over 88,000 people worldwide with annual sales of over 30 billion dollars.
