Several famous individuals are known to have contracted smallpox, including Queen Mary II of England, who suffered a severe bout that contributed to her death in 1694. Another notable figure is the American founding father George Washington, who had smallpox during a military campaign and later promoted vaccination to protect his troops. Additionally, the musician and composer Johann Sebastian Bach is believed to have contracted the disease, which affected his health in later years.
Edward Jenner is credited with introducing the smallpox vaccine in 1796. He discovered that milkmaids who had contracted cowpox, a less severe disease, appeared to be immune to smallpox. Jenner tested this hypothesis by inoculating a young boy with cowpox, and later exposing him to smallpox, which confirmed the vaccine's effectiveness. This groundbreaking work laid the foundation for modern immunology and vaccination practices.
