History
In 1898 the Rochusclub Düsseldorfer Tennisclub was founded. In 1905 the club staged the first Internationale Düsseldorf tournament. In 1929 the club moved to a new location where it remains today. It was held annually in Düsseldorf, Germany until 1977. The combined event was sanctioned by the Deutscher Lawn Tennis Bund (f.1902). From 1914 until 1969 it was an ILTF sanctioned event. In 1970 the men's event was rebranded as the Dusseldorf Grand Prix and in 1975 it became part of the Grand Prix tennis circuit. The women's event remained a part of the ILTF Circuit under the original name Dusseldorf International. In 1973 the women's event was branded as the WTA Düsseldorf Open and was part of the 1973 WTA Tour for one edition only, before it returned as an event on the ILTF Independent Tour. The women's event ended in 1974 and the men's tournament was discontinued in 1977 and replaced at the same location by the Nations Cup.
