[10] He was drafted again and spent 1953 to 1955 as chief of pathology for the Medical Nutrition Laboratory at Fitzsimons Army Hospital in Aurora, Colorado.
This led to a series of important discoveries about the genetics of inherited blood diseases and the populations they affect, especially in the Middle East, Africa and America.
[11] Bowman joined the faculty of the University of Chicago in 1962 as assistant professor of medicine and pathology and director of the hospital's blood bank.
He was a member of the national advisory group that urged the Nixon administration to initiate the inception of the Comprehensive Sickle Cell Center, which served as a model of patient-centered disease management and research.
These laws could "revive many of the past misadventures and racism of eugenics movements," he argued at the time, adding that adult screening programs create "inaccurate, misleading, politically motivated propaganda which has left mothers frantic."
In 1973, he was named to two federal review committees designed to oversee sickle cell screening and education and to evaluate laboratory diagnostic techniques.
[12] Upon his death, the University of Chicago established the Bowman Society as an advising group to support minority scholars pursuing careers in the biomedical sciences and to organize a regular lecture series.
