Hendrik Christoffel "Henk" van de Hulst FRS[1] (Utrecht, November 19, 1918 – Leiden, July 31, 2000) was a Dutch astronomer and mathematician.
In 1944, while a student in Utrecht, he predicted the existence of the 21 cm hyperfine line of neutral interstellar hydrogen. After this line was discovered, he participated, with Jan Oort and (not this) Alex Muller, in the effort to use radio astronomy to map out the neutral hydrogen in our galaxy, which first revealed its spiral structure.
He published well known book on light scattering and developed anomalous diffraction approximation describing light scattering by optically soft and large spheres.
He spent most of his career at the University of Leiden.
