He won a Caldecott Honor in 1950 for illustrating Ruth Krauss's The Happy Day, and in in 1957 he was awarded the Caldecott Medal for his pictures in A Tree is Nice, by Janice May Udry. Simont has illustrated nearly a hundred books, working with authors as diverse as Margaret Wise Brown and James Thurber. His first illustrations for a children's book appeared in 1939. Simont settled in America permanently, determined to support himself as an artist. Though he later attended art school in Paris and New York, he considers his father to have been his greatest teacher.

Encouraged by his father, Joseph Simont, an artist and staff illustrator for the magazine L'Illustration, Marc Simont drew from a young age. His parents were from the Catalonia region of Spain, and his childhood was spent in France, Spain, and the United States. Many of Thurber s famous short stories?such as The Dog that Bit People, The Night the Bird Fell, and The Secret Life of Walter Mitty have been compiled into anthologies, and his classic tale about the daydreaming everyman served as the inspiration for the 2013 film The Secret Life of Walter Mitty starring Ben Stiller and Kristen Wiig.

Thurber left The New Yorker in 1933 but continued to contribute regularly until 1950. He joined the staff of The New Yorker in 1927 and began drawing cartoons in 1930. In 1925, Thurber relocated to New York and became a reporter for the New York Evening Post. Thurber attended Ohio State University, but never graduated as a result of his poor eyesight. James Thurber was an American author and cartoonist best known for his illustrations and short stories published in The New Yorker magazine.
