November 16, 1818 Youngest Senator When the Senate convened on November 16, 1818, it set a record that will never be broken. Members on that occasion, however, probably did not realize they were making history - and violating the Constitution - in administering the oath of office to Tennessee's twenty-eight-year-old John Eaton. http://www.senate.gov/artandhistory/history/minute/Youngest_Senator.htm Had someone in 1818 chosen to challenge his seating, Eaton could have pointed to the Senate's 1816 decision to seat Virginia's twenty-eight-year-old Armistead Mason or the 1806 precedent to admit twenty-nine-year-old Henry Clay. On June 21, 1935, (Rush) Holt followed in the line of Eaton, Mason, and Clay as the Senate's fourth youngest member. In January 1973, the distinction of becoming the youngest since Holt - at the age of thirty years, one month, and fourteen days - went to Delaware's Joseph Biden. Dec 11 02, 9:38 AM
