John Holmes Jackson (March 21, 1871 – December 15, 1944) was an American politician who served as the 24th and 26th Mayor of Burlington, Vermont.[1] His father, a Canadian born to American parents, was a Congregationalist pastor who attended the International Congregational Council in 1891.[6] During World War II, Jackson, James J. Carney, and Phillips M. Bell were appointed by Governor William Wills to serve as Burlington's rationing board.[11] During his tenure in 1918 he handled the Spanish flu outbreak in the city and motorized the fire department and in 1919 he became one of the first Vermonters and politicians to ride in a seaplane.[17] In the 1930 House election he endorsed former Burlington municipal court judge Joseph A. McNamara in his unsuccessful run.
