Abstract
Abstract Arne Bjerhammar is well known worldwide mainly for his research in physical geodesy but also for introducing a new matrix algebra with generalized inverses applied in geodetic adjustment. Less known are his developments in geodetic engineering and contributions to satellite and relativistic geodesy as well as studies on the relation between the Fennoscandia land uplift and the regional gravity low. Most likely part of his research has contributed to worldwide political relaxation during the cold war, which deed was honored by a certificate of achievement awarded by the Department of Research of the US army as well as the North Star Order by the King of Sweden. Arne Bjerhammar’s pioneer scientific production, in particular on a world geodetic system, towards what would become GPS, as well as relativistic geodesy, is still of great interest among the worldwide geodetic community, while the memories and spirit along his outstanding academic deeds have more or less fainted away from his home university (KTH) only a decade after he passed away.
Highlights
Until 1949 the only professorship in Sweden was at Royal Institute of Technology (KTH), but during the 1950ties - 1970ties new professors of geodesy were installed at KTH, the Swedish Mapping Authority (RAK) and Uppsala University, sometimes called “the three Swedish kings of geodesy”

There, Bruzelius writes that considerable research in physical geodesy at KTH was paid by the USA with the main purpose of better calculating orbits for satellites and ballistic robots
Summary
He published about 60 scienti c reports and articles, and several foreigners got their PhDs in Geodesy with him at UU On his 70-ties birthday he was honored by the Aboa Astronomic Observatory (whose personnel he was in close contact with ever since his early academic days as a pioneer astronomer at Saltsjö Baden observatory outside Stockholm) by their naming the newly discovered asteroid no. After completing high school in Helsingborg in 1938 followed by military service, he started his studies at KTH, where he completed a M.Sc. in Surveying (1942), Doctor’s Grade in 1948 (see Bjerhammar 1948a) and was appointed Docent (1950) and Professor of Geodesy (1952), all at KTH, where he was active till his retirement in 1983.
