Vaizey was born in Greenwich on 1 October 1929, the younger Child of Ernest Vaizey, wharfinger, and Lucy Butler Hart. He died in London on 19 July 1984 at the age of fifty-four. He attended Colfe's Grammar School, Lewisham, but at the age of thirteen he contracted osteomyelitis in the spine, before the days of penicillin, and spent the rest of his school years in hospital. Much of the time he was lying on his stomach, in plaster up to his neck; the pain never entirely left him. This experience lay behind what the Labour MP Frank Field has described as Vaizey's most important book Scenes from Institutional Life (1959), in which he raised questions about the abuse of Power in institutions and whether work in an institution was in itself corrupting.
