Carnegie Mellon professor turned "Last Lecture" Internet sensation Randy Pausch has died. He was 47.
Last September, Pausch's "Last Lecture" speech -- which was actually called "Really Achieving Your Childhood Dreams" -- became a viral phenomenon and was even retold in its entirety on Oprah.
Pausch had been battling pancreatic cancer and passed away early this morning. He is survived by his wife and three children.
