Crystallography of Biological Macromolecules History
1895: W. C. Roentgen discovers X rays (Bragg, p. 1). 1912: Max von Laue discovers X-ray diffraction by crystals (Bragg, p. 7). 1913: W. L. Bragg reports the crystal structure of NaCl, providing the first experimental evidence for the absence of salt "molecules". (Bragg; Glusker p. 3). 1928: Kathleen Lonsdale reports the structure of benzene as having six equal sized bonds instead of alternating double and single bonds (Glusker, p. 3). 1935: J. M. Robertson et al. solve the structures of pthalocyanins, the first case of a complex organic molecule solved independently by crystallography (Bragg, p. 180). 1948: Bijvoet et al. solve strychnine, perhaps the first case in which crystallography decided between alternatives proposed by organic chemists (Bragg, p. 182). 1950: Bijvoet et al. establish the absloute configurations of dextro and laevo compounds with NaRb tartrate (Bragg, p. 188). : Dorothy Crowfoot Hodgkin et al. solved the structures of penicillin (1949) and vitamin B-12 (1957). She won the Nobel Prize in Chemistry in (Bragg, p. 189)
