Julie Mayer

Julius Mayer, known as Julie Mayer, was a South African tennis player.

Mayer was a nephew of South African Davis Cup representative Syd Levy.

Nicknamed "Big Julie", Mayer represented South Africa in both the Davis Cup and Maccabiah Games. He won a gold medal in doubles at the 1957 Maccabiah Games partnering Abe Segal, to whom he lost the singles final. In 1961, Mayer was a member of the South Africa Davis Cup team which faced Romania in Bucharest and he defeated a young Ion Țiriac in a five–set match. He held a match point against Bob Hewitt in his second round loss at the 1961 French Championships and was runner–up to Gordon Forbes at that year's South African Championship.

Mayer, a University of the Witwatersrand law graduate, ended up immigrating to Sydney, Australia.
