Sir Oswald Birley (1880 -1952) was one of Britain’s most successful portrait painters. From 1919 until the early 1950s he was the go-to artist of the time, commissioned by the Royal family, the aristocracy, politicians, artists, scientists –leading figures of their day. His work hangs in many of the UK’s major palaces, country houses, institutions and private homes; his paintings rarely leave the walls which they were designed to adorn.
