Madeline Yale Wynne (September 25, 1847 − January 4, 1918) was an American artist, teacher, writer, and philanthropist.  In 1895 she turned to writing; Madeline’s supernatural short story “The Little Room” was published in Harper’s Magazine and was well received. It was later released in a collection of Wynne’s short stories called The Little Room and Other Stories, along with The Sequel to the Little Room. (More recently, “The Little Room” appeared in the 2009 horror compendium, American Fantastic Tales, edited by Peter Straub.) She wrote for Atlantic Monthly, Harper’s Monthly, Home Beautiful, and various other publications.

Madeline helped to found and lead the Deerfield Society of Arts and Crafts in 1901, which became an umbrella organization for the arts movement in the village. Wynne served as the curator as the movement produced a broad array of artistry, including jewelry, photography, weaving, basketry, rugs, and furniture. She and Annie became very influential in developing arts and crafts in the community, with Madeline organizing tours of the village’s craftwork and arranging speaking engagements. The two women were expert metal smiths in their own right.
