Rat Poison

In the early 1920s, a bunch of cattle started bleeding to death from eating moldy sweet clover. Karl Link and Harold Campbell, chemists at University of Wisconsin, identified the anticoagulant substance in that clover as a coumarin derivative. Link then worked on making coumarin derivatives for rat poison, finally coming up with the commonly known drug warfarin. So where did the name come from? It stems from WARF, the Wisconsin Alumni Research Foundation + -arin from coumarin.
