Mary A. Conlon

Mary A. Conlon (1870 – 1936) was an American elementary school principal who founded Walton High School as one of the first all-girl schools in New York City.

Conlon was principal of the elementary school Public School 30 (P.S. 30) in the South Bronx. In 1923 she founded Walton High School, which she named after Mary Walton, the wife of Lewis Morris, a U.S. Constitution signatory. The school was first established in P.S. 30 next to the churchyard where Mary Walton and her husband are buried. The first graduation took place in January 1926 with 128 girls.

From 1930 Conlon spent two years supervising the construction of a new building on Jerome Avenue and West 195th Street to house the school. She continued as principal until her death in 1936.
