Örebro November 26 1895 –Saltsjöbaden (outsideStockholm )June 25 1965 ) was a Swedishastronomer .After finishing his secondary education at
Örebro högre allmänna läroverk , Lindblad matriculated atUppsala University in 1914. He received his "filosofie magister" degree in 1917, his "filosofie 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 of galaxies. By making careful observations of the apparent motions of stars, he was able study the rotation of the Galaxy. 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 by Jan Oort in 1927. A certainclass of
resonances in rotatingstellar orgaseous disks are namedLindblad resonances , after Bertil Lindblad.His son,
Per-Olof Lindblad , also became an astronomer.Honors
