Randy Pausch was a professor of computer science, human computer interaction, and design at CMU Pittsburgh. He also co-founded the CMU Entertainment Technology Center, and created the Alice software project. He was diagnosed with pancreatic cancer on September 2006, and he was told in August 2007 that he only had at most 6 months to live. He went on to survive almost a year after that, passing away on July 25, 2008.
After getting diagnosed in August, he gave his "Last Lecture" on the topic "Really Achieving Your Childhood Dreams" and one on time management, both of which became really well-known. His book "The Last Lecture" was a New York Times best-seller.
