Richard Hefter met children's author Jacquelyn Reinach in 1975. He was contracted at the time to write 26 books for the publishers Holt. After the contract expired he formed a publishing venture, Euphrosyne, with Reinach. He is known as the creator of Stickybear and as the co-creator (with Reinach) and illustrator for the Sweet Pickles[1] library of books, and for the Strawberry Library of First Learning. The Sweet Pickles series went on to sell 40 million copies. Hefter described his aim as "trying to help children understand things like shyness, laziness and embarrassment in a humorous way."
