Sir Cecil Walter Hardy Beaton CBE, (14 January 1904 – 18 January 1980) was an English fashion and portrait photographer and an Academy Award-winning stage and costume designer for films and the theatre.

Beaton was born on 14 January 1904 in Hampstead the son of Ernest Beaton, a prosperous timber merchant, and his wife Etty Sissons. His grandfather had founded the family business of Beaton Brothers Timber Merchants and Agents, and his father followed into the business. Ernest Beaton was also an amateur actor and had met his wife, Cecil's mother, when playing the lead in a play. She was the daughter of a Cumbrian blacksmith who had come to London to visit her married sister. They had four children - in addition to Cecil there were two daughters Nancy and Baba, and another son Reggie. Cecil Beaton was educated at Heath Mount School (where he was bullied by Evelyn Waugh) and St Cyprian's School, Eastbourne, where his artistic talent was quickly recognised. Both Cyril Connolly and Henry Longhurst report in their autobiographies being overwhelmed by the beauty of Beaton's singing at the St Cyprian's school concerts. When Beaton was growing up his Nanny had a Kodak 3A Camera, a popular model which was renowned for being an ideal piece of equipment to learn on. Beaton's nanny began teaching him the basics of photography and developing them in his basement. He would often get his sisters and mother to sit for him. When he was sufficiently proficient, he would send the photos off to London society magazines, often writing under a pen name and ‘recommending’ the work of Beaton.

Beaton went on to Harrow, and then, despite having little or no interest in academia, moved on to St John's College, Cambridge, and studied history, art and architecture. Beaton continued his photography, and through his university contacts managed to get a portrait sitting with the Duchess of Amalfi — actually George "Dadie" Rylands, and as Beaton recalled years later: "It was a slightly out-of-focus snapshot of him as Webster's Duchess of Malfi standing in the sub-aqueous light outside the men's lavatory of the ADC Theatre at Cambridge." The resulting images gave Beaton his first ever piece of published work when Vogue magazine bought and printed the photos.
