Alexander Brook (1898-1980) learned to paint at the age of twelve when he was bedridden with polio. He went on to study at the Art Students League in New York. He served as the assistant director of the Whitney Studio Club (which became the Whitney Museum of Art). Brook spent much of the 1940s in Savannah, Georgia, and eventually retired to Sag Harbor, New York. 

His three covers for The Saturday Evening Post were completed between 1945-1947; all three feature seated portraits of children. He was known for painting in the American Realism style, which favored contemporary scenes of everyday activities.
