Mary Noel Arrowsmith (May 28, 1890 – October 7, 1965) was an American educator who was awarded a Croix de Guerre for her work with YMCA in France during World War I.

[5][6] During World War I, Arrowsmith worked with YMCA in France in 1918, running a canteen near the front, alongside Gertrude Sumner Ely of Philadelphia.

"[8] She shared a place of honor in a 1919 parade in New York, with fellow YMCA war workers Ely, Frances Gulick, Ethel Creighton Torrance, and Marjorie Skelding.

[13] "Safety education does three things," she explained: "First it makes the child alive to the dangers with which complex modern life surrounds him and skilful in combating them.

Third, it awakes in the child a sense of the value and preciousness of human life and his responsibility in keeping himself sound and whole, and in making his home, his school, and his community a safe place to live in.
