Jean Marzollo was the award-winning author of over 100 books for kids, including the I SPY series, Pierre the Penguin, Help Me Learn Numbers 0-20, Soccer Sam, Happy Birthday Martin Luther King, Close Your Eyes, Mama Mama/Papa Papa, the Shanna Show books, and In 1776, as well as books for parents and teachers. She was the author/illustrator of Ten Little Christmas Presents, Ten Little Eggs, Bible stories, and Greek myths. On her website Jean Marzollo discussed her books, answered the main question kids asked: "Why did you write that book?" and also provided free original eBooks she had created. Jean blogged weekly for pre-K and kindergarten teachers. A graduate of the University of Connecticut and Harvard Graduate School of Education, Jean was editor of Scholastic's kindergarten magazine Let's Find Out from 1972-1992. Because she loved kids, early childhood education, and books, she thanked her publishers for supporting her career. She was very grateful for the artists and photographers who had illustrated her books and for her husband Claudio Marzollo and sons Dan Marzollo and Dave Marzollo, who had co-authored some of her books and helped with others, especially the I SPY books.
