Stanley Woodward Sr. (March 12, 1899 – August 17, 1992) was the White House Chief of Protocol under Franklin Delano Roosevelt and United States Ambassador to Canada under Harry S. Truman. He was a favorite social companion of FDR. Notable for his cautiousness in protecting Axis diplomats at the onset of World War II, he was also largely responsible for the introduction of black tie attire as acceptable formalwear. In his youth, he had an inclination for the Bishop's robe.
