Randy Pausch, the man whose inspirational "last lecture" about living life to the fullest even while he battled cancer, has died. ABC News first reported the story this morning. ABC's Diane Sawyer anchored an hour-long special with Pausch in April, seven months after Pausch delivered that "last lecture" at Carnegie Mellon. The lecture has been viewed more than three million times on YouTube.

Pausch succumbed to pancreatic cancer today. He was 47.

> Update: ABC News is putting together an hour-long special on Pausch that will air Tuesday night at 10pmET/PT. Diane Sawyer will anchor.
