 Adams was the first president to have been the son of a former President–John Adams; and Calhoun, at age 42 on Inauguration Day, was the second-youngest vice president (after Daniel D. Tompkins, who was 3 months younger when inaugurated into office in 1817).Chief Justice of the United States John Marshall administered the Oath of office to the new president.Adams, as he recalled later, placed his hand upon on a book of law rather than the Bible itself as he recited the oath.
