Marcia Anastasia Aitken, Baroness Beaverbrook (née Christoforides, previously Lady Dunn; 27 July 1909 – 28 October 1994) was a British philanthropist, an art collector, and racehorse owner. Early life and first marriage Born in Sutton, Surrey, England, she was the daughter of John Christoforides, a Cypriot tobacco merchant, and Mildred Nightingale-Boyes. For a number of years she worked as personal secretary for the wealthy Canadian financier James Hamet Dunn, 1st Baronet.
