This lady is one of the most important women you’ve never heard of, but the world is a much safer place thanks to her. She was a brave traveller, and one of the things she brought back from Turkey was the skill of immunizing against smallpox. Unfortunately it involved the use of pus from infected people so had a risk of giving people the disease as well as various other infections but she was responsible for saving thousands of lives in Britain & her colonies, paving the was for Jenner’s safer method using serum from cowpox.
This was her husband. He’s less famous but looks rather formidable, as was his wife.
