Town Hall: Pittsburg Municipal Building, PO Box 140, Pittsburg, OK 74360.
The Town of Pittsburg is located approximately twenty miles southeast of McAlester on State Highway 63. Non-Indian settlement can be traced to 1899 when Daniel Edwards and his son Thomas sank a coal mine shaft in the Choctaw Nation, two miles east of Kiowa. In 1903 the Post Office Department established a post office named Cowpers in the vicinity and appointed Daniel Edwards as postmaster. Later that year, the town name changed to Edwards. In 1909 Edwards again changed it to Pittsburg, which was incorporated in 1912. [ www.okhistory.org ].
