Jack David DunitzFRS (29 March 1923 – 12 September 2021) was a British chemist and widely known chemical crystallographer. He was Professor of Chemical Crystallography at the ETH Zurich from 1957 until his official retirement in 1990. He held Visiting Professorships in the United States, Israel, Japan, Canada, Spain and the United Kingdom.
In 1953 he married Barbara Steuer and had two daughters Marguerite (1955) and Julia Gabrielle (1957).[1]
Dunitz's main research direction involved the use of crystal structure analysis as tool for studying chemical problems. In his early pre-ETH period, his work included structure studies of cyclobutane,[4] of ferrocene with the first description of its electronic structure in terms of orbital symmetry relationships.[5][6] With Leslie Orgel he also explained distortions of certain spinel minerals from cubic symmetry in terms of the Jahn-Teller effect.[7] In his later research, at the ETH Zurich and after, Dunitz worked in several areas of structural chemistry, including the conformation and reactivity of medium-ring cycloalkanes and lactams,[8][9] ion-specificity of natural and synthetic ionophores,[10][11][12] chemical reaction paths (see Bürgi-Dunitz angle),[13][14][15] aspects of hydrogen bonding,[16][17][18] molecular motions in solids,[19][20][21][22] phase transformations and solid-state chemical reactions,[23][24] electron density distributions in crystals,[25][26]polymorphism,[27] and intermolecular interactions in condensed phases.[28][29] A few other publications on mathematical or theoretical topics may be of interest.[30][31][32][33][34] Dunitz was also known for Dunitz's Rule: "Almost every scientific publication can be improved by cutting out the first sentence".
Dunitz wrote more than 380 scientific papers[49] and was the author of "X-Ray Analysis and the Structure of Organic Molecules" (Cornell University Press, 1979; Verlag Helvetica Chimica Acta, Basel, 1995), and "Reflections on Symmetry in Chemistry...and Elsewhere" (with Edgar Heilbronner, Verlag Helvetica Chimica Acta, Basel, 1993). He was Co-Editor (with J. A. Ibers) of "Perspectives in Structural Chemistry", John Wiley and Sons, Vols. 1–4 (1967– 1971) and (with H.-B. Bürgi) of the two-volume "Structure Correlation", Verlag Chemie, Weinheim, 1994.
Death
Dunitz died on 12 September 2021, at the age of 98 after a short illness.[50]
