Madison Grant was a lawyer and wildlife conservationist who advocated for eugenics policies in the US during the late nineteenth and early twentieth centuries. In his 1916 book, The Passing of the Great Race; or, The Racial Basis of European History, Grant argued that what he called the Nordic race, which originated from northwest Europe, was biologically and culturally superior to all other people, including other Europeans. Grant drew from his now-discredited claims to lobby for laws in the US that restricted immigration, legalized sterilizing people against their will, and prohibited interracial marriage. Adolf Hitler referred to Grant’s book as his Bible and it was listed during the Nuremberg Trials in the late 1940s as evidence that eugenics did not solely originate in Germany. Grant’s advocacy of eugenics shaped policy that restricted reproductive freedom and immigration in the US and helped legitimize genocide in Europe.
