He joined the Nazi Party in 1928 and was the Gauleiter of North Westphalia from 1931 to 1945, the Oberpräsident of the Province of Westphalia from 1938 to 1945 and the Reichsstatthalter of Lippe and Schaumburg-Lippe from 1933 to 1945. In 1941 he became the Permanent Deputy to the Reichsminister of the Reich Ministry for the Occupied Eastern Territories. He represented the ministry with Georg Leibbrandt in the January 1942 Wannsee Conference, at which the genocidal Final Solution to the Jewish Question was planned. Near the end of World War II in Europe, Meyer committed suicide in April 1945.
