Dorothy Pulis Lathrop was an American writer and illustrator of children's books. Lathrop wrote and illustrated nine children's books and several topical nonfiction books. More than 38 books were published with her illustrations. She was also an accomplished printmaker. Much of her work was devoted to the beauty and importance of animals.
Her career began around 1919, when her first published suite of illustrations appeared in Walter de la Mare's book for children, The Three Mulla-Mulgars. Lathrop developed a friendship with de la Mare, and thereafter illustrated five more of his books for children: Down-Adown-Derry (1922), Crossings (1923), The Dutch Cheese (1931), Mr. Bumps and His Monkey (1942) and Bells and Grass (1942).
In 1929, Lathrop illustrated Rachel Field's successful children's novel, Hitty, Her First Hundred Years, the fictional story of a doll. In 1931, Lathrop wrote The Fairy Circus, which was a runner-up for the Newbery Medal. In 1938, Lathrop’s illustrations for Animals of the Bible, written by Helen Dean Fish, won her the inaugural Caldecott Medal, awarded for the year's "most distinguished American picture book for children".
Lathrop illustrated many other books, particularly fantasy and fairy tales such as W. H. Hudson's Little Boy Lost; Hans Christian Andersen's The Little Mermaid; Hilda Conkling's Silverhorn; George MacDonald's The Princess and Curdie and The Light Princess; Jean Ingelow's Mopsa the Fairy and her self-authored The Lost Merry-Go-Round and The Colt from Moon Mountain. She also illustrated several collections of children's poetry including work by Walter de la Mare and Sara Teasdale's Stars To-night.
