The 45th German International Tennis Championships took place from August 6 to August 12, 1951 on the Rothenbaum in Hamburg .
With participants from 19 nations, the tournament experienced a further boom. On Wednesday all games had to be canceled due to continuous rain, on Friday gusts of wind swept over the courts, but the event was still able to be concluded on Sunday on time.
The men's competitions were dominated this time by players from Scandinavia. In an all-Swedish final, Lennart Bergelin beat Sven Davidson in five sets . The Dane Kurt Nielsen had previously defeated the defending champion Jaroslav Drobný in the quarter-finals . In his last individual participation in Rothenbaum, Gottfried von Cramm made it to the semifinals again, which he lost to Bergelin 6-8 in the fifth set. The men's doubles were won by the Danes Kurt Nielsen and Torben Ulrich against von Cramm and Rolf Göpfert , which gave them revenge for the defeat they had previously suffered in the Davis Cup in Berlin .
In the women's category, the Australian Nancye Bolton was unbeatable in the absence of defending champion Dorothy Head . She won the final against the title holder from 1949, the Argentine María Weiss , in two sets. With her compatriot Clare Proctor , she also won the women's doubles. She achieved her third title with the oldest tournament participant, 52-year-old Jean Borotra , in a mixed competition. In 1938 she had already won the two double competitions with Thelma Coyne and Jean Lesueur .
