Robert Alvin Lewis (October 18, 1917 – June 18, 1983) was a United States Army Air Forces officer serving in the Pacific Theatre during World War II.

He was the co-pilot and aircraft commander[2] of the Enola Gay, the B-29 Superfortress bomber which dropped the atomic bomb Little Boy on the Japanese city of Hiroshima on August 6, 1945.

Lewis tried to correct the general as to his rank, but LeMay insisted on captain, with the field commission arriving several weeks later by USAAF mail to him based in the midwestern US at the time.

Articles from New York City area newspapers attested to his "cool head under stressful conditions", ultimately leading to his selection as captain of a B-29 crew.

Lewis led hundreds of bombing runs from Utah to Salton Sea in California leading up to his selection with his crew by Colonel Paul Tibbets.

His log, the only minute-by-minute recording on paper by any crew member that day, is part of his copyrighted historical manuscript owned by the Lewis children.

He left in 1947 to rejoin his prewar employer, the Henry Heide Candy Company, where he became plant manager and personnel director of their factory in New Brunswick, New Jersey.
