Hilda Elsie Marguerite Patten, CBE (née Brown; 4 November 1915 – 4 June 2015), was a British home economist, food writer and broadcaster. She was one of the earliest celebrity chefs (a term that she disliked at first) who became known during World War II thanks to her programme on BBC Radio, where she shared recipes that could work within the limits imposed by war rationing. After the war, she was responsible for popularising the use of pressure cookers and her 170 published books have sold over 17 million copies.
