Gustav Strömberg was educated at Gothenburg, Kiel, Stockholm, and Lund universities. From 1906 to 1913, he was an assistant at the Stockholm Observatory. In 1917, he went to the United States and joined the staff of Mount Wilson Observatory.

Strömberg’s first important work was on the luminosity of the long-period variable stars. His work on the radial motions of stars and nebulae led to his striking discovery, announced in 1923, of the “asymmetry of stellar motions” explicable in the Lindblad-Oort theory of galactic rotation, enunciated soon afterward.

Strömberg also attempted to correlate radial velocities of nebulae, measured by  Vesto Slipher, with estimates of their distances, in about 1925. This was before  Edwin Hubble established the redshift-distance relation. Strömberg’s version included the possibility of negative velocities, so as to include the globular clusters.
