John Donald ("Don") Budge (June 13 1915 - January 26 2000) was an American tennis champion who was a World No. 1 player for 5 years, first as an amateur and then as a professional.

Budge was considered to have the best backhand in the history of tennis, at least until the emergence of Ken Rosewall in the 1950s and '60s. Wikipedia
