Iza Trapani was born in Poland, and when she first came to the United States at the age of seven, she learned English in large part by reading a book of Mother Goose. She is the author of many books for children, some of which were based on beloved nursery rhymes such as Mary Had a Little Lamb, I'm a Little Teapot, and the bestselling The Itsy Bitsy Spider, which recently celebrated its twentieth anniversary. Iza lives in upstate New York.
