Bridget Rose Dugdale (born 1941 in Honiton, Devon), better known as Rose Dugdale, is a former debutante who rebelled against her wealthy upbringing, becoming a volunteer in the militant Irish republican organisation, the Provisional Irish Republican Army (IRA). As an IRA member, she took part in the theft of paintings worth IR£8 million and a bomb attack on a Royal Ulster Constabulary (RUC) station using a hijacked helicopter.
Dugdale was born into a wealthy English family, her millionaire father was an underwriter at Lloyd's of London who owned a 600-acre (2.4 km2) estate near Axminster in Devon. The family also owned a house in London near Chelsea Hospital, and Dugdale was educated at the nearby Miss Ironside's School for Girls in Kensington, west London. She was a popular pupil, with Virginia Ironside stating "Everyone adored this generous, clever and dashing millionaire's daughter, who was life and laughter". After completing her early education Dugdale was sent abroad to attend finishing school, then in 1958 she was presented as a debutante before Queen Elizabeth II at the start of the social season. Her debutante ball was held in 1959, with Dugdale describing it as "one of those pornographic affairs which cost about what 60 old-age pensioners receive in six months". Later that year Dugdale began reading philosophy, politics and economics at St Anne's College, University of Oxford. While studying there she began what newspapers would later describe as a "lunge to the left", when she and a fellow student gatecrashed Oxford Union wearing wigs and men's clothing in protest at the Union's refusal to admit women. After completing her studies at Oxford she travelled to the United States attending Mount Holyoke College in South Hadley, Massachusetts, where she obtained a master's degree in philosophy, submitting a thesis on Ludwig Wittgenstein. She also studied at the University of London, obtaining a Ph.D. in economics.
