I am currently revising a short story, about dueling and Laws of Science and saints and Jesuits. Well, fictionalized Jesuits, anyway.
As part of this, I've been researching scientists. Today, I discovered that astronomer Tycho Brahe lost part of his nose in a dueling accident when he was twenty, and wore a false nose of gold and silver for the rest of his life. Scientists and dueling, all in one! I was including him anyway, for reasons I'm going to keep to myself for now, but that just makes it even better.
