Glenn Murphy received his masters in science communication from London's Imperial College of Science, Technology and Medicine. He wrote his first popular science book, Why is Snot Green?, while managing the Explainer team at the Science Museum in London. In 2007 he moved to the United States. He now lives and works in Raleigh, North Carolina, with his wife, Heather, and two unusually large and ill-tempered cats.
Lorna Murphy is Glenn's sister. She studied children's book illustration at Cambridge School of Art. She is obsessed with illustrated books and also writes. Originally from Kent, Lorna now lives in Suffolk with her partner and when not creating books in her studio, she works with children in local schools and public libraries. This provides lots of inspiration for her creative work and ensures her shelves are always full of fantastic books.
