The Norwegian physician Kristian Feyer Andvord (1855–1934) who had no training in epidemiology, observed differences in mortality rates from tuberculosis between counties in Norway late 19th century and started in the 1890s to speculate on why the rates differed between counties and had fallen for infants but not adults. This triggered him to spend his career on the natural history of tuberculosis by means of population data and made him suggest that primary infection with tuberculosis mainly takes place in childhood and that falling mortality rates at the time of observation was a reflection of exposure early in life.1 Wade Hampton Frost later published a similar idea citing Andvord, and in 1939 he introduced the concept of ‘cohort’.2 This seminal paper by Frost is widely known in epidemiology as it marks the birth of a concept vital to the discipline's self-identification.3–6 Less attention has been paid to Andvord predating Frost
