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.
Born in Sutton, Surrey, England, she was the daughter of John Christoforides, a Cypriot tobacco merchant, and Mildred Nightingale-Boyes.[1] For a number of years she worked as personal secretary for the wealthy Canadian financier James Hamet Dunn, 1st Baronet. Eventually their working relationship became personal although he was thirty-six years her senior. In 1942 she became his third wife after she had nursed him back to health from a coronary thrombosis which nearly claimed his life; his second wife was absent from his bedside during this crisis. She had been a devoted employee and he would seek her input on most every business matter for the rest of his life. The couple maintained homes in England, France, and at the seaside resort of St. Andrews in New Brunswick, Canada, the province of her husband's birth. In the late 1940s, Lady Dunn and her husband developed a friendship with the Spanish artist Salvador Dalí who painted several portraits of them, notably Equestrian Fantasy - Portrait of Lady Dunn. These works are now on permanent display at the Beaverbrook Art Gallery in Fredericton, New Brunswick.
Known as Christofor to her family and friends, on the death of her husband in 1956 she became the beneficiary of a large estate and also the administrator of a fund to be used for charitable purposes. One of her late husband's closest friends was his fellow New Brunswicker, Max Aitken, 1st Baron Beaverbrook who acted as her advisor. The two developed a very close friendship and Lord Beaverbrook, who had been a widower for many years, came to have great respect for her. In June 1963 the eighty-four-year-old Beaverbrook and the fifty-three-year-old Lady Dunn married. Lord Beaverbrook had already used his fortune to greatly benefit the citizens of the province of New Brunswick in Canada. By virtue of their marriage, Aitken was able to name her the legal overseer of a large part of his estate that he wished to go to further charitable works.
Lord Beaverbrook died a year after their marriage and Lady Beaverbrook was left with the responsibility of large benevolent fund. With this, and the funds from her first husband's estate, she became one of Canada's most prominent philanthropists. On behalf of her first husband considerable funds were donated to his alma mater, Dalhousie University in Halifax, Nova Scotia. In 1967, she was awarded an honorary Doctor of Law (LL.D.) from that institution and in 1968 she was appointed the University's Chancellor, a position she held for the next twenty-seven years.
Lady Beaverbrook's high-profile in British society and the publicity from her philanthropic work resulted in an assassination attempt. On 4 May 1971 a bomb was strapped to the underside of her Rolls-Royce Phantom VI car (which is coloured green and brown, her horse racing colours), placed there by The Angry Brigade, a British terrorist group. The device was detected before it exploded. The car was donated to the National Motor Museum, Beaulieu, which sold it at auction in 2015.[2]
A devotee of show horses and equestrian events, she was also a leading race-horse owner, spending a vast amount of money on horses. Her horses almost always had names made up of seven letters. Amongst the many thoroughbreds she owned were:
She started owning horses in the late 60s and initially had her horses trained by Sir Gordon Richards. In 1971 on his retirement, she transferred them to Dick Hern. In later years she had horses with Clive Brittain. She bred horses as well as owning them.
Lady Beaverbrook died in 1994 having donated the equivalent of nearly $300 million (at today's value) to support education, cultural undertakings and wildlife preservation. In addition to the charitable trusts from both of her husbands, the Christofor Foundation for charitable purposes was established by friends out of her personal estate. A lover of animals, among the many philanthropic causes Lady Beaverbrook supported, the established the Sir James Dunn Animal Welfare Centre at the University of Prince Edward Island with a $2.2 million gift. Amongst other worthwhile causes, the Foundation from her personal estate also helped fund the Science East Association in Fredericton, New Brunswick. Because the Province of New Brunswick was home to both of her husbands, it contains many institutions built with funding from their estates. However, large contributions were made to numerous causes throughout the four Atlantic Provinces, most notably in education. In her memory, the Sir James Dunn Foundation of Saint John, New Brunswick made a $1 million donation toward the establishment of a student residence bearing her name at Acadia University in Wolfville, Nova Scotia. Christofor Hall was officially opened on 26 October 2002.
