(CNN) — Randy Pausch, the professor whose “last lecture” became a runaway phenomenon on the Internet and was turned into a best-selling book, died Friday of pancreatic cancer, Carnegie Mellon University announced on its Web site.

Pausch, 47, a computer science professor, delivered the lecture, “Really Achieving Your Childhood Dreams,” at Carnegie Mellon in September 2007, a month after being told he had three to six months to live because his cancer had returned.
The lanky, energetic Pausch talked about goals he had accomplished, like experiencing zero gravity and creating Disney attractions, and those he had not, including becoming a professional football player.
