Eleazer Root (March 6, 1802 – July 25, 1887) was an American educator and Episcopalian priest from New York, who moved to Wisconsin as a young man and spent much of his career and adult life there.
He served a term in the Wisconsin Assembly and was appointed as the first Superintendent of Public Instruction.
Because of his health, in his last years he moved to St.
Augustine, Florida, serving as rector of Trinity Parish from 1874 to 1884.
Root is considered as one of the founding fathers of Wisconsin and was also instrumental in organizing the University of Wisconsin as a member of the first board of regents.
