Claire Gordon was born in Cambridge, in England. Her father was a doctor and her mother a make-up artist who worked for Max Factor. After being photographed by chance at the Queens Ice Rink, Bayswater, for the cover of the magazine Lilliput, Claire Gordon was signed to a five-year contract with film agent Bill Watts and played a harem girl in the Bernard Bresslaw film I Only Arsked! (1958), before making her first stage appearance, still aged only seventeen, in Meet the Cousin, which starred Cicely Courtneidge and Jack Hulbert. The show opened at the Lyceum Theatre, Edinburgh, and it was there that she met her husband-to-be William Donaldson, later better known as Henry Root, who was just starting out as a theatrical producer. Following a spell in repertory at the New Theatre Royal, Portsmouth, playing a Russian spy in Agatha Christie’s Verdict and a gum-chewing blonde in Brighton Rock and some pre-London tours, she made her West End theatre debut on a motorbike in The Darling Buds of May at the Saville Theatre; and then played the role of Peggy, a dumb blonde film starlet, in a show-stopping scene with Michael Crawford in Neil Simon’s first hit Come Blow Your Horn at London’s Prince of Wales Theatre, Later, at Donaldson’s request, she appeared as an entirely French-speaking Lady Fifi de Winter in an improvised production of The Three Musketeers with Bruce Lacey and The Alberts, at the Arts Theatre. Donaldson’s talent for presenting controversial and often money-losing shows didn’t desert him; the show ran for two weeks; and Gordon made theatrical history as the first actress to appear naked on stage.(“Watch out for the bath scene; it’s a breakthrough”, wrote The New Statesman.) Most recently, she played the Fairy Godmother in Cinderella at the Princess Theatre, Hunstanton, and worked with Sarah Louise Young in Clive Evans’s two woman show The Nunnery.

Claire Gordon married Donaldson on 1 September 1967. Usually impecunious, a year later he inherited a fortune on the death of his grandmother. Donaldson’s biographer later noted that the marriage was “not an easy one”. After it broke down, Gordon joined the Open University and went on to graduate from Middlesex University with a BA degree in English and American History and Literature. Claire Gordon was with Dr Stephen Ward the night that he met Christine Keeler, and with William Donaldson when the police raided and planted hash in their Chelsea flat; for which the policemen were later jailed. By the end of her life, she had been working on her memoirs and a documentary about her experiences while living in Egypt before and after the 2011 revolution.
