    Manganese was platted by the Duluth Land and Timber Company in 1911, established on March 13, 1912, and incorporated on November 10, 1913, with 960 acres (390 ha) in the corporate limits. An official U.S. Post Office opened in 1912 and remained in operation through 1924. In 1914, the town site had a crew of men and teams building streets with concrete sidewalks and curbing, although the clay roads were never paved. The Soo Line Railroadconstructed a siding
