What is the name of the serial killer in The Silence of the Lambs?

If you could pinpoint the exact moment when it became acceptable to joke about serial killers who eat people, it was probably when The Silence of the Lambs was released in 1991.

From quipping that you'll eat whatever it is with a nice "side of Chianti" to answering every call with, "Hello, Clarice," this was a seminal film that quickly made its way into the cultural lexicon.

So who were agent Starling and co. after in the movie, anyway?
