Emerging disciplines in the border zone between physics and chemistry have 1 attracted the attention of historians of science particularly in the last 20 years. 2 Quantum chemistry, as an offshoot of theoretical chemistry, has recently acquired 3 some importance in the history of chemistry. It is the product of close 1 Cf. Hiebert, E. : Discipline Identi cation in Chemistry and Physics, in: Science in Context, 9(2) (1996), 93-119; Nye, M.

To my knowledge it was coined by the physicist Arthur Haas. Talks he had del- ered before the Viennese Chemico-Physical Society in the spring of 1929 are assembled in his book: Die Grundlagen der Quantenchemie: Eine Einleitung in vier Vortrage. It was published by the Akademische Verlagsgesellschaft in Leipzig.
