Beatrice Mabel Cave-Browne-Cave (1874–1947) was an English mathematician who undertook pioneering work in the mathematics of aeronautics.
Beatrice Cave-Browne-Cave was the daughter of Sir Thomas Cave-Browne-Cave (1835–1924) (see Cave-Browne-Cave Baronets for earlier history of the family) and Blanche Matilda Mary Ann Milton. She was the sister of Henry Cave-Browne-Cave, the Royal Air Force officer. She was educated at home in Streatham and entered Girton College, Cambridge with her younger sister Frances Cave-Browne-Cave in 1895. Gaining a second-class degree in the mathematical tripos part one in 1898, she took part two in 1899 and was placed in the third class.
After eleven years teaching mathematics to girls at a high school in Clapham in south London, in the years just before the First World War she worked under Professor Karl Pearson[1] in the Galton Laboratory at University College, London. During the war Beatrice carried out original research for the government on the mathematics of aeronautics; this remained classified under the Official Secrets Act for fifty years. Elected an associate fellow of the Royal Aeronautical Society in 1919 and awarded an MBE in 1920, she later worked as an assistant to Sir Leonard Bairstow, the Zaharoff Professor of Aviation at Imperial College, London. She retired in 1937, continuing to live in Streatham.[2]
