Tony Ross was born in London in 1938. He trained at the Liverpool School of Art and has worked as a cartoonist, a graphic designer, as the Art Director of an advertising agency, and as Senior Lecturer in Art at Manchester Polytechnic. He has illustrated books for many authors including Roald Dahl and Paula Danziger, but he also writes and illustrates his own books. His series of books about extra-terrestrial teacher Dr. Xargle, written with Jeanne Willis, have become extremely popular, as has his much-loved Towser series.
