Dame Kathleen Lonsdale, DBE FRS (née Yardley, 28 January 1903 – 1 April 1971) was a British crystallographer, who finally proved that the benzene ring was flat by X-ray diffraction methods in 1929. She was the first to use Fourier spectral methods while solving the structure of hexachlorobenzene in 1931. During her career she attained a number of firsts for a woman scientist, including one of the first two women elected a Fellow of the Royal Society in 1945 (along with Marjory Stephenson), first woman tenured professor at University College London, first woman president of the International Union of Crystallography, and first woman president of the British Association for the Advancement of Science.
