Kenneth Robert Rosewall is an Australian former world top-ranking amateur and professional tennis player. He won a record 23 Majors in singles, including eight Grand Slam singles titles and, before the Open Era, a record 15 Pro Slam titles. Rosewall also won a record 24 major men's doubles titles, with nine Grand Slam titles and 15 Pro Slam men's doubles titles. Rosewall had a renowned backhand and enjoyed a long career at the highest levels from the early 1950s to the early 1970s. Rosewall was ranked as the world No. 1 tennis player by multiple sources from 1961 to 1964, multiple sources in 1970 and Rino Tommasi in 1971 and 1972. Rosewall was first ranked in the top 20 in 1952 and last ranked in the top 20 in 1977. Rosewall is the only player to have simultaneously held Pro Grand Slam titles on three different surfaces (1962–1963). At the 1971 Australian Open, he became the first man during the Open Era to win a Grand Slam tournament without dropping a set. Rosewall won world professional championship tours in 1963, 1964, and the WCT titles in 1971 and 1972. A natural left-hander, Rosewall was taught by his father to play right-handed. He developed a powerful, effective backhand but never had anything more than an accurate but relatively soft serve. He was 1.70 m tall, weighed 67 kg (148 lb) and sarcastically was nicknamed "Muscles" by his fellow-players because of his lack of them. He was, however, fast, agile, and tireless, with a deadly volley. Now a father of two and grandfather of five, Rosewall lives in northern Sydney.
