155083 Banneker           Discovered 2005 Sept. 30 by L. Molnar at the Calvin-Rehoboth Observatory.
Benjamin Banneker (1731-1806) was a freeborn African-American farmer, clockmaker, writer and scientist. Self-taught in mathematics and astronomy, he wrote six published almanacs that sold throughout the mid-Atlantic region. He assisted in the 1791 survey of the Federal Territory (the District of Columbia).
