Which U.S. President was the only one sworn in by his father?
Answer: Calvin Coolidge was sworn in as the 30th U.S. President by his own father – one of those quirks of history not likely to be repeated. He took office on August 3, 1923, following the sudden death of President Warren G. Harding. Vice President Coolidge was in Vermont visiting his family home, which had neither electricity nor a telephone, when a messenger brought word of Harding’s death. His father, a notary public, administered the oath of office in his family’s parlor by the light of a kerosene lamp.
