Dr. Charles Armstrong (1886-1967), surgeon and virologist, experiments on a rabbit for the Public Health Service in the USA in 1935. He is assisted by Irvin Norfalk, a laboratory technician. Armstrong coined the name Lymphocytic choriomeningitis (LCM) in 1934 after isolating a previously unknown virus. He worked on transmission of poliovirus, and in 1939 made discoveries which paved the way for research that successfully produced effective vaccines against poliomyelitis.
