Ambler, Mary Cary (fl. 1700s)

American diarist.

While living in Jamestown, Virginia, Mary Cary Ambler discovered that doctors in Baltimore, Maryland, had learned how to inoculate children against smallpox. With her children in tow, she headed north, keeping a journal of her three-month trek. The Diary of M. Ambler (1770) details the trip and the early history of the smallpox vaccine.
