Marc Simont, French-American illustrator (d. 2013)
Marc Simont (November 23, 1915 – July 13, 2013) was a Paris-born American artist, political cartoonist, and illustrator of more than a hundred children's books. Inspired by his father, Spanish painter Joseph Simont, he began drawing at an early age. Simont settled in New York City in 1935 after encouragement from his father, attended the New York National School of Design, and served three years in the military.

Simont's first illustrated children's book was published in 1939. He won the 1957 Caldecott Medal for U.S. children's book illustration, recognizing A Tree Is Nice by Janice May Udry, and he was a runner-up both in 1950 (The Happy Day by Ruth Krauss) and in 2002 (The Stray Dog retold by Simont).

He also illustrated The 13 Clocks (1950) and The Wonderful O (1957) by the writer James Thurber; In the Year of the Boar and Jackie Robinson by Bette Bao Lord (1984); Top Secret by John Reynolds Gardiner (1995); My Brother, Ant by Betsy Byars (1996); and The Beautiful Planet: Ours to Lose, which he also wrote (2010), and illustrated “The Trail Driving Rooster” by Fred Gipson (1955).

Simont and writer Marjorie W. Sharmat created the boy detective Nate the Great in 1972, and he illustrated the first twenty cases, through 1998.

As cartoonist for the Lakeville Journal in Connecticut, he won the 2007 James Aronson Award for Social Justice Journalism from Hunter College.

He died at his home in West Cornwall, Connecticut on 13 July 2013 at the age of 97. He was survived by his wife Sara "Bee" Dalton.
