Ralph Albert Gilman (March 25, 1916 – October 5, 1955) was an American competition swimmer who represented the United States in the 1936 Summer Olympics in Berlin, Germany.[1] Gilman swam for the silver medal-winning U.S. team in the first round of the men's 4×200-meter freestyle relay.[1] [2] He did not receive a medal, however, because only those relay swimmers who competed in the event final were medal-eligible under the 1936 Olympic swimming rules.
Gilman was the younger brother of 1928 Olympic swimmer Marian Gilman.[3]
