The husband-and-wife team Leo (1933 — 2013) and Diane (1933– ) Dillon met while training at Parsons School of Design and married shortly after graduating in 1956.  Over the course of 50 years, they collaborated on over 100 magazine and book covers.  Among numerous awards, the Dillons won the Caldecott Medal in both 1976 and 1977, the only time that the award has been won consecutively.
