Terence V. Powderly

Terence Vincent Powderly (January 22, 1849 – June 24, 1924) was an American labor union leader, politician and attorney, who was the Grand Master Workman of the Knights of Labor from 1879 to 1893.

Born in Carbondale, Pennsylvania, he was later elected mayor of Scranton, Pennsylvania, for three 2-year terms, starting in 1878. A Republican, he served as the United States Commissioner General of Immigration in 1897. The Knights of Labor was one of the largest American labor organizations of the 19th century, but Powderly was a poor administrator and could barely keep it under control. His small central office could not supervise or coordinate the many strikes and other activities sponsored by union locals. Powderly believed that the Knights were an educational tool to uplift the workingman, and he often cautioned against the use of strikes to achieve workers' goals.

Powderly's influence reportedly led to the passing of the alien contract labor law in 1885 and the establishment of labor bureaus and arbitration boards in many states. The Knights failed to maintain its large membership after being blamed for the violence of the Haymarket Riot of 1886. It was increasingly upstaged by the American Federation of Labor under Samuel Gompers, which coordinated numerous specialized craft unions that appealed to skilled workers, instead of the mix of unskilled, semiskilled, and skilled workers in the Knights.
