Playing career
George Martin Lott Jr. was born in Springfield, Illinois, on 16 October 1906 and grew up in Chicago. He won four Illinois state high school titles from 1922 to 1924, played shortstop for the University of Chicago, and won the Big Ten singles and doubles in 1929 before graduating in 1930. As a teenager he won the Cincinnati tournament in 1924 and 1925; he won it four times in all.
His best years were 1928 to 1934. He won the US doubles five times with three partners: John Hennessey in 1928, John Doeg in 1929 and 1930, and Lester Stoefen in 1933 and 1934. He added three US mixed titles, two with Betty Nuthall and one with Helen Jacobs, and at Wimbledon won the doubles in 1931 with John Van Ryn and in 1934 with Stoefen, and the mixed in 1931 with Anna Harper. In singles he reached the 1931 US final, losing to Ellsworth Vines 7-9, 6-3, 9-7, 7-5. He played Davis Cup in six years between 1928 and 1934 and never lost a doubles rubber.
In November 1934 he signed a professional contract with the promoter Bill O'Brien, and from January 1935 toured with Stoefen, Bill Tilden and Vines. He later wrote for Tennis Magazine, co-wrote How to Play Winning Doubles (1980), and from 1969 until his death in 1991 coached the men's team at DePaul University in Chicago, by then the oldest college coach in the country. He entered the International Tennis Hall of Fame in 1964.
