Carl Gustaf "Gösta" Abrahamsson Forssell (2 March 1876 – 13 November 1950) was a Swedish medical researcher and professor in radiology and radiotherapy.
His father Abraham Forssell was an agronomist and businessman; Carl Gustav was the eldest of seven brothers,[1] most of whom also became scientists, engineers and historians, and he also had two sisters.
[2][3] His doctoral thesis, on the relationship between X-rays of the human stomach and its anatomical structure, won the 1917 Jubilee Prize of the Swedish Medical Society.
[1][5] In 1903 and 1908 he visited France and observed pioneering work with radiation and electricity, including by Antoine Béclère and Jean Bergonié.
[3] His reports on the radium treatment of cancer, particularly uterine cancer, in what became known as the "Stockholm model", in particular "Erfarenheter om radiumbehandling av underlivskräfta vid Radiumhemmet i Stockholm 1910–1913" (Hygiea, 1915), were widely read and influential,[3] as was his "Studies of the mechanism of movements of the mucous membrane of the digestive canal" (The American Journal of Roentgenology, 1923).
