Born in Amsterdam, Adriaan Blaauw studied astronomy at the Universities of Leiden, where he worked with Jan Oort and Ejnar Hertzsprung, and Groningen, where he earned his doctorate under Pieter van Rhijn. In 1945 he returned to Leiden, from which he participated in an expedition to Kenya in 1949-50, and made lengthy visits to Yerkes Observatory, where he became a member of the staff in 1953. Four years later he returned to the Netherlands to become director of the University of Groningen’s Kapteyn Astronomical Laboratory, which he rebuilt into a major research center concentrating on galactic structure. His scientific contributions concerned the motions of star clusters and associations, “runaway stars,” star formation, and the determination of the cosmic distance scale. From 1975 to 1981 he was a professor at Leiden. Blaauw was a leader in international collaborations. He played a significant role in the construction of the European Southern Observatory in Chile, serving two years as scientific director and then as director general from 1970 to 1974. He lent ESO support and became the first chairman of the board of directors of Astronomy and Astrophysics, when that journal was formed by the merger of most European astronomy journals in 1968. He chaired the Scientific Proposals Selection Committee for the astrometric satellite HIPPARCOS. After his 1981 retirement he returned to the Kapteyn Institute at Groningen and wrote several historical articles and books, mostly on international organizations and collaborations in astronomy, but also on Dutch farmhouses and the village in which he lived.
