Margaret Widdemer (September 30, 1884 - July 14, 1978) was an American poet and novelist. She won the Pulitzer Prize (known then as the Columbia University Prize) in 1919 for her collection The Old Road to Paradise, shared with Carl Sandburg for Cornhuskers. She graduated from the Drexel Institute Library School in 1909. She first came to public attention with her poem The Factories, which treated the subject of child labor. In 1919, she married Robert Haven Schauffler (1879-1964), a widower five years her senior. Schauffler was an author and cellist who published widely on poetry, travel, culture, and music. His papers are held at the University of Texas at Austin.
