Millard F. Hopper's Lectures on Checkers are Regular Feature 1933-1934
Millard Fillmore Hopper (1897-1985) learned how to play checkers at a Greenwich Village recreation center. In time he became champion of the corner-store 'Go-As-You-Please' (GAYP) or 'freestyle' form of competitive checkers, as opposed to the traditional tournament style in which two or three moves are determined in advance. Hopper demonstrated his chops at the 1939 World's Fair, where he set up a booth and played nearly 5,000 games, reportedly losing only three. His program aired on WNYC October, 1933 through July, 1934.
