Garnet Ault’s greatest moment in swimming came at the 1928 Summer Olympics, where he won a bronze medal in the 4x200 metre freestyle relay alongside Munroe Bourne, Walter Spence, and Jimmy Thompson. He was also sixth in the 1,500 metre freestyle and was eliminated in the opening round of the 400 metre freestyle. Additionally, he set a Canadian record in the mile swim that year, with a time of 23:36.6. A student at the University of Michigan, he continued swimming for the school as he earned a medical degree, graduating in 1930. Specializing in proctology, he set up a practice in Washington D. C. in 1938 and worked as a surgery professor at Georgetown University. Joining the American Proctologic Society in 1937, he served as its president from 1964 through 1965 and was also vice-president of the American Board of Colorectal Surgery from 1962 through 1963 and chief of proctology at the Washington Hospital Center. He retired in 1974 and spent the rest of life between Florida and Michigan, where he died of a heart attack in September 1993.
