Playing career
Born in Johannesburg in 1952, the son of Max Bertram, South African champion in 1932, Byron Bertram attended Parktown Boys' High School and won the Wimbledon boys' singles in 1969 and 1970. He turned professional in 1970 and played the tour until 1980, reaching a career-high singles ranking of No. 51 in July 1976 and winning one doubles title, at Louisville in 1976 with Pat Cramer. He was a member of the South Africa team that won the Davis Cup in 1974, playing the last rubber of the Americas Inter-Zonal final in Bogotá; the Cup was awarded to South Africa when India refused to travel for the final in protest at apartheid. His best result at a major was the Wimbledon quarter-final of 1977, where he lost to Jimmy Connors.
