The Legend of Sleepy Hollow, by Washington Irving, has been called “America’s First Ghost story." It is, perhaps, the story that most represents the Halloween season. But it also works in a lot of history, history that deserves to be remembered.
In 1933 a farmer named Ed Carlson walked into a laboratory at the University of Wisconsin and asked a simple question- what was killing his cattle? The answer to that question would earn the university millions of dollars, and revolutionize the fields of both medicine and vermin extermination. The strange story of warfarin deserves to be remembered.
