Philip Mason was one of three children – two sons and a daughter – of Herbert Alfred Mason (1876–1968), a
general practitioner at
Duffield, Derbyshire, and his wife Ethel Addison (1880–1956), daughter of Herbert Addison Woodruff, an engineer and manager of a
Cammell Laird steel factory. The Mason family had been farmers for several generations at
Barrowden in
Rutland,
East Midlands; his great-grandfather Henry brewed beer and sold malting barley to brewers, and his grandfather George Mason "grew first-class malting barley and reared Leicester lambs". On the basis that "Woodruff" struck him as "a prettier, a more unusual, and a more romantic name than plain ordinary Mason", he "decided very early to be Philip Woodruff Mason and was known by that name until (he) was thirteen and had to produce a birth certificate." Mason was educated at
Sedbergh School and
Balliol College, Oxford, taking a first-class degree in
Modern Greats. He published two volumes of autobiography,
A Shaft of Sunlight: Memories of a Varied Life (Andre Deutsch, 1978) and a sequel,
A Thread of Silk: Further Memories of a Varied Life (Michael Russell, 1984). ==Career with the Indian Civil Service==
