Shier Mendelson (March 23, 1894 – August 13, 1971) was a noted Canadian open water swimmer.
However, he immigrated to Canada in 1898 with his parents Hyman Mendelson (1846–1928) and Hinda, née Silverstone (1859–1942).
[citation needed] Mendelson established himself as one of the premier open water swimmers in Canada, winning the Toronto Across-the-Bay Swim (1.5 miles) four consecutive times in 1913, 1915, 1919 and 1920 respectively.
[1][2][3] In 1921, he finished fifth in the world's ten-mile championship water event in Philadelphia, and in 1924 he captured the six-mile title of the United States.
[1][5][6] It was around this time that Mendelson largely retired from professional swimming, although he sat for many years as the secretary-treasurer of the Queen City Swimming Club of Toronto.
