He studied chemistry at Uppsala University from 1907 and received his doctorate in 1915 . As a post-doctoral student he spent a year in Göttingen and from 1917 private lecturer in physical chemistry in Uppsala. From 1919 to 1921 he worked as a metallographic operator in a ball bearing factory in Stockholm and in 1921 became a private lecturer in metallography at Stockholm University , where he became professor of general and inorganic chemistry in 1927.
He dealt with colloid chemistry , where he invented the Westgren chamber (a cuvette for observation under an ultramicroscope ) and with metallography. He examined metal structures with X-rays, recognized the face-centered cubic structure of austenite , found brass structures in copper-aluminum alloys and in other alloys, which confirmed the theory of the Hume-Rothery phases .
From 1926 to 1965 he was on the Nobel Committee for Physics and Chemistry. From 1959 to 1972 he was permanent secretary of the Royal Swedish Academy of Sciences . In 1951 he was accepted as a corresponding member of the Académie des sciences .
In 1936 he received the Wilhelm Exner Medal .
