Wilding won the Davis Cup four times playing for Australasia, and won a bronze medal at the indoor singles tennis event of the 1912 Olympics which made him the first and to date only player from New Zealand to win an Olympic medal in tennis in the Summer Olympics. He still holds several all time singles tennis records, namely 23 titles won in a single season (1906) and 114 career outdoor titles (shared with Rod Laver). In his ranking list of greatest tennis players compiled in 1950, Norman Brookes, winner of three Majors and president of the Lawn Tennis Association of Australia, put Wilding in fourth place. Shortly after the outbreak of World War I he enlisted and was killed on 9 May 1915 during the Battle of Aubers Ridge at Neuve-Chapelle, France. In 1978 Wilding was inducted into the International Tennis Hall of Fame.
