 With his son's help and a photographic memory, Oscar Almgren was able to continue his research; Bertil Almgren, as a child, would read academic texts out loud to his father, and starting from the age of eight would accompany him to the Royal Swedish Academy of Letters, History and Antiquities, taking notes of lectures and discussions.The experiences were formative for Bertil Almgren, who in 1965 became, like his father, a professor of Scandinavian and Comparative Archaeology at Uppsala University.Almgren was born on 9 November 1869, and died on 13 May 1945, at the age of 75.
