1950 OD. Discovered 1950 July 25 at the Goethe Link Observatory at Brooklyn, Indiana.

Named in honor of Albrecht Unsoald {1905-1995}, author of Physik der Sternatmospharen, long-term professor and director of the Institute for Theoretical Physics at the Christian Albrecht University at Kiel. A student of Sommerfeld's, he pioneered the use of physics in understanding the structure of stellar atmospheres through the analysis of the strengths and profiles of spectral lines, and he sowed the seeds for the new science of laboratory astrophysics as a source of information about the properties of atoms and for the simulation of physical conditions in astronomical objects. Unsaold is respected as much for his vision for the future of astronomy as for his deep sense of appreciation for its history. (M 12969)
