HistoryNamed after James Mourilyan Tanner (1920-2010), a British pediatric endocrinologist who received his medical doctorate from the University of Pennsylvania in 1944, as well as a fellowship in endocrinology from Johns Hopkins as a result of a Rockefeller exchange grant program. A supurb hurdler and athlete prior to WWII, he likely would have competed in the in 1940 Olympics. Following his training stateside, he would return to England to oversee a national study on the effects of malnutrition on children. While documenting and analyzing the data, he noticed a trend of secondary physical characteristics as children and adolescents developing into adulthood. This led to a 20-year longitudinal study on human development and the publication of his eponymous staging system in 1962 in his classic textbook “Growth at Adolescence”.
