Pittsburg sprang up in the fall of 1876 on a railroad line being built through the neighborhood. It was named after Pittsburgh, Pennsylvania, and maps of the time give the town's name as "New Pittsburgh". George Hobson and Franklin Playter are credited with being the city's founders, establishing a government after its beginnings as a coal mining camp in the 1870s. The city was incorporated in 1879. The “New” was dropped upon incorporation of the City as a third class city on June 21, 1880, with M. M. Snow as its first Mayor. In 1892 it was advanced to a city of the second class, in 1905 Pittsburg attained the rank of first class.
