Charles Armstrong (physician)
Charles Armstrong ( 25 September, 1886 – 23 June, 1967) was an American physician in the U.S. Public Health Service. He coined the name Lymphocytic choriomeningitis in 1934 after isolating the hitherto completely unknown virus. He discovered in 1939 that poliovirus can be transmitted to cotton rats, and started self-tests with nasal spray vaccination. Additional recommended knowledge
EducationIn 1905 Charles Armstrong graduated from Alliance High School and went on to
Mount Union College Preparatory School from 1905–1906. He took a B.S. degree from Mount Union College, Alliance, Ohio in 1910. In 1915 he graduated from Johns Hopkins Medical School, with an M.D. degree and did a General Internship at Yale-New Haven Hospital until 1916. Civilian Work ExperienceOn 16 October , 1916 he was commissioned to the U.S. Public Health Service and served for
six weeks at the Immigration Station, Ellis Island, New York.
From November 1916 to September 1918 he was Medical Officer on the United States Coast Guard Cutter (CSG) Seneca assigned to Cuban and European waters for 17 months until the ship was transferred to the U.S. Navy during World War I.
When in the fall of 1918 local outbreaks of pandemic influenza occurred Armstrong was in the investigating team.
From 1919 to 1921 he worked as an Epidemiological Aide to the Ohio State Department of Health.
For the next decades, from 1921 until his retirement from active duty in 1950 he worked at the Hygienic Laboratory, remaining there through its administrative and name changes to the National Institutes of Health.From 1950 to 1963 Armstrong went on at the Institute doing daily research work without compensation. Two outstanding achievements in virological researchArmstrong's world wide recognition as a virologist is due (a) to his dicovery, in 1934, of the virus that is the agent in a clinical entity, which he named lymphocytic choriomeningitis (LCM) and (b) to his successful work in polio research and polio prevention. LCMIn 1934 Armstrong isolated a previously undescribed neurotropic virus found during the experimental transmission of encephalitis virus from the 1933 St. Louis epidemic from which it was differentiated and he demonstrated the virus in the central nervous system, spinal fluid, blood and urine of monkeys and in the brain and blood of mice during the experimental disease. In the majority of the monkeys there was more or less diffuse and irregular cellular infiltration of the meninges.In most animals there was a more or less pronounced swelling, edema and lymphocytic infiltration of the choroid plexus,i.e. the the cellular membrane lining the intracerebral ventricles, which led him to name the disease lymphocytic choriomeningitis.[1] Polio
While sitill doing research work on LCM in 1939, Armstrong was able, for the first time, to adapt and transmit a human strain of poliovirus (the rarer and less dangerous Lansing type 2 strain[2] ) from monkeys to small rodents, first to the cotton rat (Sigmodon hispidus hispidus) and then to white mice. This accomplishment was revolutionary as it made possible the study of many aspects of infection and immunity in humans that could scarcely have been carried out with monkeys. The discovery also stimulated the renewal of efforts to adapt and establish the other immunologic types of poliomyelitis, leading to methods that resulted in the eventual developments of successful vaccines for poliomyelitis.[3] Honors Received by Charles Armstrong
