Powderly was an American labor union leader, politician and attorney, best known as head of the Knights of Labor in the late 1880s, one of the largest American labor organizations of the 19th century. Powderly led the Knights to a membership that was upwards of 800,000 and included both African Americans and women, although many lodges in the U.S. South were segregated.
