Mo Willems

Maurice Charles Willems (born February 11, 1968) is an American writer, animator, voice actor, and children's book author. His work includes creating the animated television series Sheep in the Big City for Cartoon Network, working on Sesame Street and The Off-Beats, and creating the children's book Knuffle Bunny and the children's book series Elephant & Piggie.

Early life Willems's parents were from the Netherlands and grew up there during World War II. His mother was a corporate attorney and an honorary consul to the Dutch Embassy. His father was from Nijmegen. When Willems was about three years of age, he took interest in cartoon artwork, drawing and creating his own characters. Willems enjoyed writing stories about his characters to share with others. However, he was disappointed when adults would praise his work politely, as he wanted feedback on the quality of his stories. To fix this dilemma, Willems wrote comedic stories, following the notion that even polite adults would not fake a laugh. When adults laughed, Willems assumed his story was good, and if the adults only gave polite comments, Willems assumed his story needed improvement.

After graduating from New York University's Tisch School of Arts, Willems spent a year traveling around the world drawing a cartoon every day, all of which have been published in the book You Can Never Find a Rickshaw When it Monsoons.

Career Returning to New York, he started his career as a writer and animator for Sesame Street, where he earned six Emmy Awards for writing during his tenure from 1993 to January 2002. The segments he wrote and animated for the show included a series of short segments featuring the recurring character Susie Kabloozie, and her pet cat, Feff. During this period he also performed stand-up comedy in NYC and recorded essays for BBC Radio along with making a promo for Cartoon Network and animating the opening for a show on Nickelodeon. He later created two animated television series: The Off-Beats for Nickelodeon and Sheep in the Big City for Cartoon Network. Sheep in the Big City was a success with the critics but ultimately failed to attract sufficient viewership and was canceled after two seasons. Willems later worked as head writer on the first four seasons of Codename: Kids Next Door, — and to his pigeon character as "one of this decade's contributions to the pantheon of great picture book characters." He also creates the Elephant and Piggie books, an early reader series about a friendly elephant and pig.
