Bengt Georg Daniel Stromgren (21 January 1908 - 4 July 1987) was a Danish astronomer and astrophysicist who did important research in stellar structure in the 1930s but is best known for his work on ionized gas clouds - H II regions - around hot stars. He surveyed H II regions and found relations between the gas density, the luminosity of the star, and the size of the Stromgren sphere of ionized hydrogen around it.
