Biography
Hemelrijk received his PhD in 1950 at the University of Amsterdam with a thesis entitled "Symmetry Keys and other applications of the theory of Neyman and Pearson" under supervision of David van Dantzig.Han Oud en Gerard Alberts (2010) "[http://vvs-or.cpu.nl/db/upload/documents/Journals/STAtOR/STAtOR_2000-3_totaal-1.pdf Een statisticus moet ook wel eens geluk hebben’ Interview met prof. dr.

After graduation Hemelrijk started his academic career as assistant to David van Dantzig at the Centrum Wiskunde & Informatica in Amsterdam, and later Head of the Statistical Consulting Department. He was Professor at the Delft University of Technology from 1952 to 1960. In 1960, he was appointed Professor of Statistics at the University of Amsterdam as successor of David van Dantzig.{{Cite journal |last1=Hemelrijk |first1=J. |author-link=Jan Hemelrijk |date=1960 |title=The Statistical Work of David Van Dantzig (1900-1959) |url=http://resolver.tudelft.nl/uuid:87ecaad6-3585-490a-a5eb-10f3234928a0 |journal=Annals of Mathematical Statistics |publisher=Duke University Press |volume=31 |issue=2 |pages=269–275 |doi=10.1214/aoms/1177705893 |access-date=16 December 2023|doi-access=free }} Among his doctoral students were Gijsbert de Leve (1964), Willem van Zwet (1964), R.
