Matthew Oldham & Lizzie Cope

Matthew Oldham writes books for Usborne about all sorts of subjects, including history, science and Planet Earth. Before he did this, he studied English at university and worked for the BBC where he made funny radio programmes. He lives in London and spends his weekends visiting its many museums and exploring different parts of the city.

Lizzie Cope grew up in Wiltshire, not far from Stonehenge - she has this to thank for her love of nature, legends and World Heritage sites. Now she lives in London, where she's written books about giraffes, oceans and plastic, and thought up lots of ideas for puzzles and activities, too.
