John Buettner-Janusch was one of the first Americans to study lemurs. He held prestigious faculty positions at Yale, Duke and NYU, before surprising everyone with a series of increasingly bizarre crimes.

You can learn more about lemurs at The Duke Lemur Center (https://lemur.duke.edu/), which Peter Klopfer and John Buettner-Janusch founded together.
