Anders Oscar Ahlgren (12 February 1888 – 27 December 1976) was a Swedish Greco-Roman wrestler.[1] He was a world champion in 1913 and finished second in 1911 and 1922.
At the 1912 Summer Olympics, Ahlgren won the silver medal in the light heavyweight class. In a remarkable final, he wrestled for nine hours against Ivar Böhling, before the bout was declared a draw. The judges refused to award a gold medal, and gave silver medals to both wrestlers.[2]
Ahlgren was coached by Iivari Tuomisto, a Finnish heavyweight wrestler.
Besides wrestling Ahlgren was involved in the production of canned food and co-owned a mink farm.
