Bertil Lindblad

Born 26 Nov 1895; died 26 Jun 1965 at age 69.Swedish astronomer who contributed greatly to the theory of galactic structure and motion and to the methods of determining the absolute magnitude (true brightness, disregarding distance) of distant stars. He theorized that the areas around the center of a galaxy revolve and this is why it was flattened. Oort later proved that does indeed happen. He studied the structure and dynamics of star clusters, estimated the Milky Way's galactic mass, the period of our Sun's orbit, confirmed Harlow Shapley's direction and approximate distance to the center of the Galaxy, and developed spectroscopic means of distinguishing between giant and main sequence stars.
