Joe Fullman is a freelance author based in London. Over the past 20 years, he has - by a rather neat symmetry - written and contributed to guidebooks to around 20 countries. That means he's visited an awful lot of museums - although he's always happy to fit in a couple more. In between his foreign adventures, Joe has also found time to write children's books on everything from dinosaurs and space to music and ancient history. Joe also authored Incredible Cabinet of Wonders for Lonely Planet Kids, released in October 2017.
