William Renshaw, English tennis player (died 1904)

William Charles Renshaw was a British tennis player active during the late 19th century, who was ranked world No. 1. He won twelve Wimbledon titles: seven in singles and five in doubles. A right-hander, Renshaw was known for his power and technical ability which put him ahead of competition at the time. His seven Wimbledon men's singles titles were a record that stood for 128 years, until surpassed in 2017. His six consecutive singles titles (1881–86) remain an all-time record. Additionally, Renshaw won the doubles title five times with his twin brother Ernest. William Renshaw was the first president of the British Lawn Tennis Association (LTA).
