M. P. Robertson was born in Parsons Green, London. He studied Graphic Design at Hounslow Borough College, where he discovered a love for illustrated books. After leaving Hounslow he spent a year drawing in museums, cathedrals and on the underground before specialising in illustration at Kingston Polytechnic. Among the influences on his style are Mervyn Peake, Heath Robinson and Odile Redon. He believes that more than merely decorating a book, illustration should be integral to the narrative. Among is books for Frances Lincoln are The Egg, The Great Dragon Rescue and The Dragon Snatcher; Hieronymus Betts and his Unusual Pets, Big Brave Brian, The Sandcastle and Food Chain. He lives in Bradford on Avon with his partner and two sons.
