Allan Ahlberg was one of the UK's most acclaimed and successful authors of children's books - including the best-selling Jolly Postman series. Born in Croydon in 1938, he was educated at Sunderland Technical College. Although he dreamed of becoming a writer since the age of twelve, his route to that goal was somewhat circuitous. Other jobs along the way included postman (not an especially jolly one, he recalls), gravedigger, plumber, and teacher.

Ahlberg wrote his first book when he was thirty-seven, after a decade of teaching - a profession that he maintains is "much harder" than being a writer. He says that if he hadn't become a writer, he would have loved to be a soccer player. He was married for many years to fellow children's author Janet Ahlberg, with whom he often worked. Their daughter, Jessica Ahlberg, is also a children's author.
