University of Wisconsin-Madison biochemist Karl Paul Link and his lab isolated an anticoagulant compound from spoiled sweet clover hay in 1939, after a Wisconsin farmer's cattle began hemorrhaging from the moldy feed. Their research led to warfarin, marketed first as a rat poison in 1948 and later approved as the blood-thinning drug warfarin sodium (Coumadin) in 1954. It remains one of the world's most widely prescribed anticoagulants.
