Existentialism. Surname means graveyard; I wonder if he picked this intentionally?

Ludwig Wittgenstein once stated that Kierkgaard was "by far the most profound thinker of the [nineteenth] century. Kierkegaard was a saint."

"Kierkegaard predicted his posthumous fame, and foresaw that his work would become the subject of intense study and research."

The first programmer. Long before there was anything like a computer, only Charles Babbage's theory which she translated to French (with extra notes), she got it – how it would work. This is hard to do when you don't grow up around computers, the idea of computation which surrounds us today and seems obvious had not occurred to anyone. Even Babbage wasn't able to envision it. That's why we say she was the first programmer.

After Babbage refused her offer to work with him, she spent ten years abusing opiates and alcohol (given by her mother who thought she should less cerebral and more ladylike), then died.

The "father of vaccines" – cool story. Jenner figured out that getting people sick with cowpox (a mild disease) made them much less likely to be killed by smallpox (a serious disease). There was already a practice called variolation which was just straight-up infecting people with smallpox. And here is the origin of the name vaccine. Cowpox is translated into Latin as variolae vaccinae ("cow's smallpox"). So giving people cowpox is called "vaccination".

Now vaccination is the general practice of infecting people with a mild variant of a deadly disease. Often a mild variant doesn't exist, so we craft one in the lab.
