19th century The school was founded in 1887 by
Nicholas Murray Butler as a co-educational experimental and developmental unit of
Teachers College at
Columbia University. Its first location was 9
University Place in
Manhattan's
Greenwich Village. The school moved in 1901 to 120th Street in
Morningside Heights. Horace Mann became independent of the Columbia University and Teachers College in 1940.
20th century The school split into separate all-male and all-female schools and in 1914, the Boys' School moved to 246th Street in
Riverdale, Bronx, and during the 1940s it severed formal ties with Columbia University and became Horace Mann School. The Horace Mann School for Girls remained at Teachers College, and then merged with the
Lincoln School in 1940, and finally closed in 1946. The New York School for Nursery Years (founded in 1954 on 90th Street in Manhattan) became the Horace Mann School for Nursery Years in 1968 and was co-ed. In 1972, Horace Mann merged with the
Barnard School for Boys, next door in Riverdale, to form the Horace Mann-Barnard Lower School for
kindergarten through
grade six, located on the former Barnard School campus. At that point, only the lower school was mixed. In 1975, the Horace Mann School returned to its roots as a co-educational learning environment and began admitting girls to the Upper School. The Class of 1976 is Horace Mann School's last all-male class. In 1999, the sixth grade moved from the Horace Mann-Barnard campus to the main 246th Street campus and formed a distinct Middle Division along with the
seventh and
eighth grades. The Horace Mann School was named after
Horace Mann, who was a lawyer who served in the
Massachusetts State Legislature and was the first secretary of the
Massachusetts Board of Education from 1837 and 1848, a member of the
U.S. House of Representatives, and the first
president of
Antioch College. He used each of his positions to proclaim that every person, regardless of their background, should receive a public education based on the principles and practices of a free society. Mann played a leading role in establishing the U.S. elementary school system. ==Institution==
