Timothy J. Greenwood's art education began at the Ravensbourne College of Art and was completed at the Camberwell School of Art. In 1961, at the age of 14, he was awarded the first prize for his entry in the "Out of Doors Competition" organized by the BBC Television Dept. He then appeared on television with his work in the program "Animal Magic" presented by Keith Shackleton in 1966 and then in 1971 on the same program to mark the association of his first One Man Show in London. Greenwood's copper plate etchings were hung in the Royal Academy Exhibitions of 1970, 1971 and 1973. The London British Museum of Natutral History selected and published his "Great Tit" and "Nuthatch" for their series of "British Birds by British Artists." Amongst important commissions already carried out are the illustrations for the bird section of the Shell Nature Guide to Britain, production of work for the London Natural History Museum, and illustrations for the Shooting Times.
Timothy Greenwood has a devotion to natural history subjects in which he acknowledges the encouragement and help of Peter Scott and Keith Shackelton. It was through them that he became the youngest member of Wild Life Artists in 1967. His time is decided between drawing and study of his subjects, which has included amongst other similar activities visits to the Shetlands, Spain, Norway and Morocco.
