Harry Laughlin Laughlin's work was supported on an international scale. Adolf Hitler and the Nazi regime commended Laughlin on many accounts, primarily for his theory of excluding whole races from naturalization in general. The 1933 Sterilization Laws of Nazi Germany were sculpted after theories Laughlin had explicated in Eugenical Sterilization in the United States. The University of Heidelberg in Heidelberg, Germany, granted Laughlin an honorary master's degree in 1936 for his work.
