Robert Lawson (1892–1957) received his art training at the New York School of Fine and Applied Art. His favorite medium, pen and ink, is used expressively and with detail in his black and white illustrations in The Story of Ferdinand (by Munro Leaf). In addition to illustrating many children's books, including Mr. Popper's Penguins, Lawson also wrote and illustrated a number of his own books for children. In 1940, he was awarded the Caldecott Medal for his picture book illustrations in They Were Strong and Good; and in 1944, he was awarded the Newbery Medal for his middle-grade novel Rabbit Hill.
