Charles Armstrong (September 25, 1886 – June 23, 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.
