Life

Esmond Ray Long was the second of five children of John Harper Long and Catherine Bell Stoneman. His father was a professor of chemistry at Northwestern University and later dean of the School of Pharmacology there . Esmond Ray attended the Morgan Park Academy in Chicago until 1906 and then studied privately with his father and at the University of Chicago chemistry, where he made his bachelor's degree in 1911 . He then received his doctorate in chemical pathology ( Ph.D. in chemical pathology ) at the university's medical school in 1918 under Ludvig Hakoen, and also graduated from Rush Medical College with a doctorate in 1926 . The promotion was delayed due to tuberculosis , which he in his own 1913 sputum diagnosed. Over the next five years he underwent a large number of the then common therapies and began during the first investigations in what would later become his main area of ​​research, tuberculosis. He conducted research at the University of Chicago, where he became professor of pathology in 1928 and first worked in 1923 with his long-time assistant Florence B. Seibert . His first books on tuberculosis and the history of pathology were written during his time in Chicago.

Seibert and long studied the then-available diagnostic tests for tuberculosis and showed that the immune response in normal skin test with tuberculin proteins of the pathogen Mycobacterium tuberculosis is caused. Both went to the University of Pennsylvania in 1932 , where Esmond R. Long became Professor of Pathology and Director of the Henry Phipps Institute . Florence B. Seibert developed a method for the production of a special protein extract , the so-called purified protein derivative (PPD), which became the reference standard of the US Public Health Service's Bureau of Biologics Standards for the tuberculin test in the 1940s , and in 1952 also the international standard of the World Health Organization .

Until his retirement in 1955, Esmond R. Long was mainly concerned with the diagnosis, prevention and control of tuberculosis as well as with influencing environmental factors and racial differences. He has also chaired several professional associations such as the American Association of Pathologists and Bacteriologists, and edited the International Journal of Leprosy and the American Review of Tuberculosis . He continued to study the history of medicine and published other books on the history of pathology in the United States and several scientific organizations.

Esmond R. Long was married to Marian Adams since 1922, with whom he had a son and a daughter; she died in 1974.
