In the early hours of August 3, 1923, Calvin Coolidge was sworn in as the 30th president of the United States. He took the oath at his family home in Vermont after the sudden death of President Warren G. Harding. The ceremony was conducted by Coolidge’s father, a local notary and justice of the peace. Coolidge later repeated the oath in Washington to avoid any legal questions. His presidency emphasized limited government and business-friendly policies. The quiet, reserved style that earned him the nickname “Silent Cal” contrasted with the scandals of the Harding years.
