A legend in modern day microbial-warfare, Dr. John Bartlett has been a witness to the discovery and defeat of the world's most sinister viral infections. A pioneer in the research of HIV/AIDS, C-DIFF, and antimicrobial resistance, Dr. Bartlett was Chief of the Division of Infectious Diseases at Johns Hopkins for 26 years.
Dr. Donald Ainslie (D.A.) Henderson (1928-2016) was a major figure in the fight against infectious diseases, beginning in the 1950s, when he worked for Alex Langmuir at the newly-established Epidemic Intelligence Service of the CDC. During that time, he created and operated the first Smallpox Surveillance unit in the United States.
