Leslie Kimmelman has long been associated with Sesame Workshop both as a writer and editor. She is the author of more than three dozen children's books, including The Little Red Hen and the Passover Matzah and Write On, Irving Berlin!, which were both Sydney Taylor Notable Books, and the Sydney Taylor Honor Book Everybody Says Shalom. She lives in the New York City area.

Hilli Kushnir (aka silly Hilli) is a children's illustrator living in NYC with one husband, two kids, four plants and a few house flies that are harder to keep track of. She loves pets (that belong to other people) almost as much as she loves coffee (that she drinks too much of) and riding the NYC subway.

Hilli painted a lot as a child but as an adult majored in graphic design which is a bit like drawing but with shapes and letters. After graduating she designed a bunch of stuff for the internet, but when given the chance continued drawing, mainly characters.

Today Hilli's focus is children's books which allow her to be a bit silly and less of a grown up. She loves using happy colours and her favourite subjects are cute animals or little kids with missing teeth and messy hair.
