At his retirement in 2015, John Dingell, Jr., held the record as the longest-serving Member of Congress. His lengthy congressional career began in 1955, following in his father’s footsteps as a Representative from Michigan. As a young man, Dingell, Jr., was a House Page, and he attended Capitol Page School before enlisting in the army. In the House, he chaired the Committee on Energy and Commerce from the 97th–103rd Congresses, as well as the 110th Congress. This photograph shows him presiding over the committee with a grin.
