Despite its diminutive size, the golden poison frog is one of the deadliest creatures in the world. Native to Columbia, the poisonous—but not venomous—frog contains enough of the rare neurotoxin batrachotoxin to kill 10 humans.

For his work in that field, he shared the 1951 Nobel Prize in Chemistry with chemist Glenn Seaborg. He was also involved in research on radar, sonar, and nuclear weapons during WWII and is credited with building the first synchrotron—which is what?
