"I was trying to put myself in a bottle that would one day wash up on the beach for my children"

Randy Pausch, a terminally ill professor whose earnest farewell lecture at Carnegie Mellon University became an Internet phenomenon and bestselling book that turned him into a symbol for living and dying well, died Friday. He was 47.

Pausch, a computer science professor and virtual-reality pioneer, died at his home in Chesapeake, Va., of complications from pancreatic cancer, the Pittsburgh university announced.

When Pausch agreed to give the talk, he was participating in a long-standing academic tradition that calls on professors to share their wisdom in a theoretical "last lecture." A month before the speech, the 46-year-old Pausch was told he had only months to live, a prognosis that heightened the poignancy of his address.

Delivered last September to about 400 students and colleagues, his message about how to make the most of life has been viewed by millions on the Internet. Pausch gave an abbreviated version of it on "Oprah" and expanded it into a best-selling book, "The Last Lecture," released in April.

Yet Pausch insisted that both the spoken and written words were designed for an audience of three: his children, then 5, 2 and 1.

"I was trying to put myself in a bottle that would one day wash up on the beach for my children," Pausch wrote in his book.

"The speech made him famous all over the world," Zaslow told The Times. "It was almost a shared secret, a peek into him telling his colleagues and students to go on and do great things. It touched so many people because it was authentic."
