Edward Coles was the second governor of Illinois. A former slaveowner from Virginia, Coles became an abolitionist and won the 1822 gubernatorial election as the candidate of the anti-slavery forces. He helped defeat a call for a constitutional convention to consider the legalization of slavery in Illinois. The memorial, which stands at Valley View Cemetery, was erected in 1928 and 1929 and contains a square bas-relief bronze portrait of Coles, sculpted by Leon Hermant. Coles is buried in Philadelphia, Pennsylvania.
