Berta And Elmer Hader
Berta Hoerner (1891 – 02/06/1976) and Elmer Stanley Hader (09/07/1889 - 09/07/1973) were a husband-and-wife team that illustrated more than 70 children's books, about half of which they also wrote. Their most notable contribution to children's literature was in 1949, when they won the Caldecott Medal for The Big Snow.
