John Quinn (1870-1924) was a corporation lawyer in New York City who amassed an important private collection of paintings, drawings and sculpture as well as books and manuscripts of contemporary authors. In addition to promoting modern and avant-garde art in all forms, he particularly encouraged the work of members of the Irish Literary Revival, the artists of the Paris School, and English and American writers of his time. In 1923 he sold his manuscript and library holdings to subsidize his art collection.
