“Light Horse” Harry Cooper was the professional at Glen Oak Country Club from 1930-1937 and at Northmoor Country Club from 1941-1942. During this time the nationally acclaimed champion enjoyed his greatest success as a club and touring professional. He won the 1934 Western Open at the Country Club of Peoria, beating Ky Laffoon in a second 18-hole playoff, his only major championship. He piled up many other titles, including wins in the first three tournaments held on Medinah No. 3. He dropped an 18-hole playoff to Tommy Armour in the 1927 U.S. Open and advanced to the semifinals of the 1925 PGA Championship, falling to eventual champion Walter Hagen. Statistically, Cooper's best year was 1937, when he won eight times on Tour, and was both the leading money winner and the first winner of the Vardon Trophy. He was also a two-time winner of the Illinois PGA title and the original Illinois Open.
