Mary Nelson Winslow (1887–1952) was a Washington, D.C., social worker who worked in the US Department of Labor's Women's Bureau from 1920 into the late 1930s, conducting many research projects on the status of working women.
[11] During that same time, Winslow was nominated by President Franklin D. Roosevelt as the United States' representative to the Inter-American Commission of Women (CIM).
In a large part, her nomination was used by FDR to oust Doris Stevens from the CIM and transform the organization from a quasi-autonomous advisory group into a subsidiary commission of the Pan American Union.
Winslow was appointed the US's official representative at the 1938 Conference of the Pan-American States, held in Lima, Peru[12][13] and served on the CIM until 1944.
[4] She died on May 2, 1952, in Washington, D.C.,[1] and her papers were donated by her older sister Harriet Winslow to Radcliffe College.
