View full image Before he died on December 17, 76-year-old computer science professor Stanley Eisenstat, who had been suffering from a pulmonary embolism, asked that his students not be notified of his death until the fall term ended. He was concerned that the news might affect them during the stressful exam period. Remarkable as this was, friends and colleagues say it was in keeping with the care and concern for his students—and extraordinary dedication to teaching—that Eisenstat had demonstrated for nearly a half century since joining the Yale faculty in 1971.
