Bertil Lindblad (26 November 1895 – 25 June 1965) was a Swedishastronomer.[1][2][3]
After finishing his secondary education atÖrebro högre allmänna läroverk, Lindblad matriculated atUppsala University in 1914. He received hisfilosofie magister degree in 1917, hisfilosofie licentiat degree in 1918 and completed his doctorate and became a docent at the university in 1920. From 1927 he was professor and astronomer of theRoyal Swedish Academy of Sciences and head of theStockholm Observatory. In the latter capacity he was responsible for the observatory's move from the old buildingin the centre of Stockholm to a newly built facility inSaltsjöbaden Observatory, which was opened in 1931.
Lindblad studied the theory of the rotation ofgalaxies. By making careful observations of the apparent motions of stars, he was able to study the rotation of theMilky Way. He deduced that the rate of rotation of the stars in the outer part of the galaxy, where the Sun is located, decreased with distance from the galactic core. This deduction was soon confirmed byJan Oort in 1927. A certainclass ofresonances in rotatingstellar orgaseousdisks are namedLindblad resonances, after Bertil Lindblad.
His son,Per Olof Lindblad, also became an astronomer.
