He was the son of Carl Erik Bergstrand and Jenny Rosalie Wallin, and married, first, Anna Elfrida Ericsson (1901) and, second, Ingrid Svensson (1942). Bergstrand received his Ph.D. in astronomy at Uppsala University in 1899, working under Nils Dunér, who modernized the instrumentation at Uppsala, obtaining a double refractor useful for both classical astronomy (astrometry) and astrophysics. Bergstrand worked in both of these fields.
