“Henk” van de Hulst was born and educated in the Dutch city of Utrecht, at whose university he completed his war-interrupted doctorate under Marcel Minnaert in 1946. He made his most important discovery during the war: stimulated by a suggestion of Jan Oort, van de Hulst predicted in 1944 that clouds of hydrogen gas in space should emit and absorb a spectral line at wavelength 21 cm. After this radiation was detected in 1951, he, Oort, and C. Alex Muller led the Dutch team which, along with an Australian team, mapped the clouds of the Milky Way and delineated its spiral structure. Van de Hulst made extensive studies of interstellar grains and their interaction with electromagnetic radiation. He wrote important books on light scattering and radio astronomy. He investigated the solar corona and the earth’s atmosphere. After two years at the Yerkes Observatory, he taught and researched at the Leiden University from 1948 until his retirement in 1984. He was the first president of the international space committee of COSPAR and a leader in several other international organizations and in the development of Dutch and European space research.
