Arnold Stark Lobel (May 22, 1933—December 4, 1987) was a popular American author of children's books. Among his most popular books are those of the Frog and Toad series, and Mouse Soup, which won the Garden State Children's Book Award from the New Jersey Library Association.
Lobel won the 1981 Caldecott Medal for his book Fables.
Lobel also illustrated the works of other authors. A notable example is Sam the Minuteman by Nathaniel Benchley, which was first published in 1969.
He was born in Los Angeles, California, to Lucille Stark and Joseph Lobel. When he graduated from art school, he married Anita Kempler, who would also achieve fame as a children's book author and illustrator, and they moved to New York City. He had two children: a daughter, Adrianne, who is married to actor Mark Linn-Baker; a son, Adam; and three grandchildren.
In 2009, Adrianne Lobel started releasing some of her father's archive material in the form of new books, with added watercolors by herself. The Frogs and Toads All Sang was released in May 2009, and Odd Owls and Stout Pigs is scheduled to be released in October of 2009.
