Since the 1960s, Desmond Morris has been known as a zoologist and expert on human behaviour, but the bestselling author of The Naked Ape and Manwatching has led a double life. By day, a rational scientist, writer and broadcaster with a mission to explain; by night, a painter of dreamlike images, which mystify even Morris himself. He began painting in the surrealist style while still at school and still does so today, at the age of 89. In his long career, he has been friends with such great surrealists as Joan Miro and Henry Moore. Every night, between 10 pm and 4 in the morning, while the rest of us are dreaming in our beds, Desmond Morris dreams on canvas.
