Federico Castellón was a Spanish American painter, sculptor, printmaker and illustrator of children's books. A fundamentally self-taught artist, Castellón began sketching at an early age. He took advantage of his family's relocation and visited the museums of New York. Consequently, his influences ranged from Old Masters to the modern artists of his day, including Giorgio de Chirico, Pablo Picasso, Salvador Dalí, and Georges Rouault. Castellón was introduced to Diego Rivera, who was painting murals for Rockefeller Center in New York City. The older artist took an interest in the young man's work and brought Castellón's drawings to the attention of the director of the Weyhe Gallery in New York, who subsequently gave the eighteen-year-old Castellón his first solo exhibition. In 1934, with Rivera's help, Castellón was awarded a four-year fellowship, sponsored by the Spanish Government, to travel throughout Europe to study painting and printmaking. During this same period, Castellón began to exhibit his work in museums in France and Spain.
