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).

Research
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
