IN: Stallman was born to Alice Lippman, a school teacher, and Daniel Stallman, a printing press broker, in 1953 in New York City. Stallman had a difficult relationship with his parents, as his father had a drinking habit and verbally abused his stepmother. He later came to describe his parents as "tyrants". He was interested in computers at a young age; when Stallman was a pre-teen at a summer camp, he read manuals for the IBM 7094.

As a first-year student at Harvard University in fall 1970, Stallman was known for his strong performance in Math 55. He was happy: "For the first time in my life, I felt I had found a home at Harvard." In 1971, near the end of his first year at Harvard, he became a programmer at the MIT Artificial Intelligence Laboratory, and became a regular in the hacker community, where he was usually known by his initials, RMS (which was the name of his computer accounts). Stallman received a bachelor's degree in physics (magna cum laude) from Harvard in 1974. Stallman considered staying on at Harvard, but instead he decided to enroll as a graduate student at MIT. He pursued a doctorate in physics for one year, but left that program to focus on his programming at the MIT AI Laboratory. While working (starting in 1975) as a research assistant at MIT under Gerry Sussman, Stallman published a paper (with Sussman) in 1977 on an AI truth maintenance system, called dependency-directed backtracking. This paper was an early work on the problem of intelligent backtracking in constraint satisfaction problems. As of 2009, the technique Stallman and Sussman introduced is still the most general and powerful form of intelligent backtracking. The technique of constraint recording, wherein partial results of a search are recorded for later reuse, was also introduced in this paper. As a hacker in MIT's AI laboratory, Stallman worked on software projects such as TECO, Emacs for ITS, and the Lisp machine operating system (the CONS of 1974-1976 and the CADR of 1977-1979--this latter unit was commercialized by Symbolics and LMI starting around 1980). He would become an ardent critic of restricted computer access in the lab, which at that time was funded primarily by the Defense Advanced Research Projects Agency. When MIT's Laboratory for Computer Science (LCS) installed a password control system in 1977, Stallman found a way to decrypt the passwords and sent users messages containing their decoded password, with a suggestion to change it to the empty string (that is, no password) instead, to re-enable anonymous access to the systems. Around 20% of the users followed his advice at the time, although passwords ultimately prevailed. Stallman boasted of the success of his campaign for many years afterward.
QUESTION: when did he graduate?
IN: Jean-Christophe Lafaille (31 March 1965 - 27 January 2006 [presumed]) was a French mountaineer noted for a number of difficult ascents in the Alps and Himalaya, and for what has been described as "perhaps the finest self-rescue ever performed in the Himalaya", when he was forced to descend the mile-high south face of Annapurna alone with a broken arm, after his climbing partner had been killed in a fall. He climbed eleven of the fourteen eight-thousand-metre peaks, many of them alone or by previously unclimbed routes, but disappeared during a solo attempt to make the first winter ascent of Makalu, the world's fifth highest mountain.

After Annapurna, Lafaille resolved never to climb again, but during his long physical and psychological recovery he began scrambling in the foothills of the Alps, and eventually returned to extreme climbing. In the Alps he carried out an enchainment of nine north faces in fifteen days, skiing from mountain to mountain, and made the first ascent of the Lafaille Route on the Petit Dru, which at the time was considered the hardest route in the Alps, but his most important climbs were in the Himalaya. A year after his accident on Annapurna, he climbed Cho Oyu, and then in 1994 he climbed a new route, solo, on the north face of Shishapangma. It was the first of many solo ascents of 8000 meter peaks, including consecutive ascents of Gasherbrum I and Gasherbrum II in four days in 1996, and Manaslu in 2001. Annapurna remained an obsession for Lafaille, and he would later call his autobiography Prisoner of Annapurna. He returned to the mountain three times. The first time he made a solo attempt on the British line on the South Face, which failed due to poor snow conditions. In 1998 he returned to the same route with a larger team, but the expedition was abandoned when a team member was killed in an avalanche. He finally reached the summit in 2002 with Alberto Inurrategi via the long, committing east ridge. By 2003 Lafaille had decided to try to climb all fourteen 8000-metre peaks; but unlike many of the mountaineers who take on this goal, he had no desire simply to climb them by well established routes, in large expeditions and with bottled oxygen. He preferred to continue trying to achieve new routes or solo ascents, or to climb in the more demanding winter season. In 2003 he climbed Nanga Parbat, Dhaulagiri (solo) and Broad Peak in a two-month period. The last of these nearly killed him when he fell into a crevasse and then developed high altitude pulmonary edema. He was rescued by Ed Viesturs and Denis Urubko. In December 2004 he made a solo ascent of Shishapangma. It was intended to be the first winter ascent of the mountain, but he reached the summit on 11 December which was seen as too early to be classed as a true winter ascent. By this point he had completed eleven of the fourteen peaks, and needed Everest, Kanchenjunga and Makalu to complete his goal.

Who rescued him and how?
