Krahwinkel Sperling is generally regarded as the second-greatest female German tennis player in history, behind Steffi Graf.
However, Sperling won the mixed doubles title that year, playing with Gottfried von Cramm.
From 1933 through 1939, Sperling won the singles title at the German Championships six consecutive times (the tournament was not held in 1936 because of the Berlin Olympics).
Sperling's last international singles title was at the 1950 Scandinavian Covered Courts Championships in Copenhagen, Denmark when she was age 41.
In recognition of her winning the French Championships three times, being a Wimbledon finalist twice, reaching the semifinals of the French Championships and Wimbledon an additional six times, and being ranked in the top 10 for 10 consecutive years, Sperling was inducted into the International Tennis Hall of Fame in 2013.
