Editing Two Harbors, Minnesota (section)

===Former industries===
====Cigar factories====
In 1900, John H. Kallin built Two Harbors Cigar Factory on the 100 block of 7th Street. The local trade alone required about 30,000 cigars each month. They came in eight regular brands and five specialty. In 1907 Ed Sorenson built Sorenson Cigar Factory. Neither factory is still in operation.

====Universal Fiberglass====
In 1964 the abandoned DM&IR railroad buildings were used to open Universal Fiberglass. Producing three wheel mailsters for the United States Postal Service was their main contract, worth millions. Car fenders and like objects were also produced. When a fire caused enough damage that they could no longer fulfill their contract, the GSA shut them down. The property was sold at a [[public auction]].

====Bottling works====
Two Harbors Bottling works began in 1912. It offered flavors of pop such as cream soda, ginger ale, cider, and seltzer water. The company became especially known for its strawberry pop's unique flavor—a creamier and more natural one than the rest. This business is no longer running.

====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]].
