Charlton Township is a community rich in history, as it emerged with lumbering and milling operations in 1875. Johannesburg was incorporated in 1901, home to the lumbering company of Johannesburg Mfg. Co., operated by the Sailing, Hanson and Michelson families. The town was named after Johanna Hanson, who is the wife of the president of the company. The company was responsible for much of the construction in the small town, including the development of a branch railroad line, which served as a lifeline for the town. At its peak, Johannesburg was a bustling community of 700. By 1929, 71 lumbering operations had ceased.
