Jonathan London was born a "navy-brat" in Brooklyn, New York, and raised on Naval stations throughout the U.S. and Puerto Rico. He received a Masters Degree in Social Sciences but never formally studied literature or creative writing. He began to consider himself a writer about the time he graduated from college. After college he became a dancer in a modern dance company and worked at numerous low-paying jobs as a laborer or counselor. He wrote poems and short stories for adults, earning next to nothing despite being published in many literary magazines. For some 20 years before he penned his first children's book, London was writing poetry and short stories for adults. In the early 1970s, he was reading his poems in San Francisco jazz clubs, and those experiences found their way into his witty children's book Hip Cat, which has been featured on the PBS children's television show Reading Rainbow. After writing down the tale The Owl Who Became the Moon in 1989, London began to wonder if other people might want to read it. He picked up his kids' copy of Winnie-the-Pooh and saw that the book was published by Dutton, so he casually decided to send his story to them. Surprisingly enough, they wanted to publish him. Working with different illustrators, and occasionally with co-authors, London has produced literally dozens of books. Most have appeared under his name, but some have come out under a pseudonym, which still remains a secret.He has published over forty books and has earned recognitions from organizations like the National Science Teachers Association.
