||Dame Kathleen Lonsdale, DBE, FRS (b. 28 January 1903) was a British crystallographer who proved, in 1929, that the benzene ring is flat by using X-ray diffraction methods to elucidate the structure of hexamethylbenzene.[1] She was the first to use Fourier spectral methods while solving the structure of hexachlorobenzene in 1931.
