Peter Moffett, now better known by his stage name Peter Davison, was born on 13 April 1951 in the Streatham area of London. In 1961, he and his family - parents Sheila and Claude (an electrical engineer who hailed from British Guiana) and his sisters Barbara, Pamela and Shirley moved to Knaphill, Woking in Surrey, where Davison was educated at the Winston Chirchill School. It was here that he first became interested in acting, taking parts in a number of school plays, and this eventually led to him joining an amateur dramatic society, the Byfleet Players. On leaving school at the age of sixteen, having achieved only modest academic success with three O Levels of undistinguished grades, he took a variety of short-lived jobs ranging from hospital porter to Hoffman press operator.
