The Very Hungry Caterpillar is one of the more than 70 picture books that I have written and/or illustrated. I was born in the U.S. and was raised in Germany. My background is in graphic design but since the late 1960's when I illustrated Bill Martin Jr's Brown Bear, Brown Bear, What Do You See? I have been creating books for children. My illustrations are collages made with my own hand-painted tissue papers, a technique many children have replicated and enjoyed in their classrooms and at home. With my late wife Barbara, I am also the cofounder of The Eric Carle Museum of Picture Book Art in Amherst, MA.
