Bertram Charles Percival Park, OBE, (1883-1972) was a portrait photographer whose work included British and European royalty. Engravings of his photographs were widely used on British and British Commonwealth postage stamps, currency, and other official documents in the 1930s. His theatrical portraits were the source for two paintings by Walter Sickert. With his wife Yvonne Gregory, he also produced a number of photographic books of the female nude. He was an expert in the cultivation of the rose and the editor of The Rose Annual.
Bertram Charles Percival Park was born in Minster, Kent, England, in 1883 to Charles Percival Park and Katharine Mary Park. He initially worked in the family firm which made artist's materials.
In 1916, Park married the photographer Yvonne Gregory (1889-1970) at Hampstead, and she became one of his principal models. They had a daughter, Hilary June Park, who was born in Hampstead in 1920. Hilary, known as June, was an architect who married David Francis Rivers Bosanquet in 1941 and divorced him in 1947. Her second marriage was to the Finnish architect Cyril Mardall (1909-1994) in 1947.
In 1910, Bertram Park was one of the founders of the London Salon of Photography. In 1919, with funding from the Egytologist Lord Carnarvon, he established studios at 43 Dover Street, London, with his wife Yvonne and the children's photographer Marcus Adams. They shared darkroom staff and facilities and were known as the "Three Photographers".
Park's work included British and European royalty and in 1927 he was made an MBE. In the 1939 Birthday Honours he was made up to OBE. His images were widely used on British and British Commonwealth postage stamps, currency, and other official documents in the 1930s.
