Sumner Sewall (June 17, 1897 – January 25, 1965) was an American Republican politician and airline executive who served as the 58th Governor of Maine from 1941 to 1945. He began his aviation career during World War I as a fighter ace.
He enlisted in the USAAS in Paris, underwent training, and reported to the 95th Aero Squadron in February 1918. He was promoted to Flight Commander, and went on to score five victories over enemy planes between 3 June and 18 September 1918, sharing a couple of them with future general James Knowles and Edward Peck Curtis. Sewall then became a balloon buster, shooting down an observation balloon each on 4 and 5 November. The only victory he did not receive credit for came when German pilot Leutnant Heinz Freiherr von Beaulieu-Marconnay mistakenly landed on the 95th Aero Squadron's airfield, and Sewall and a couple of other American pilots captured him at gunpoint.[1]
His political career began when he became an alderman in Bath in 1933. He was elected to the Maine state legislature as a representative in 1934, then as a senator in 1936 and 1938. After the latter election, he was named President of the State Senate. In 1940, he was elected governor, and served two terms. Sewall's administration was notable for cleaning up scandals in state government and passing a minimum wage law for state teachers.
Sewall became president of the Bath National Bank in the 1960s. He died on 25 January 1965.
