1985年4月29日,傅京孙教授因心脏病发作,突然辞世。噩耗从华盛顿传到印第安纳州的普渡大学,我和当时在普渡大学学习与工作的其它中国人一样,简直不能相信和无法接受这个事实。两天后,我参加了遗体告别仪式和追悼会,无比悲痛。国际模式识别、人工智能和自动控制科学界失去了一位天才的组织者和开拓者,我们失去了一位可亲可敬的良师益友。 April 29, 1985, Professor Fu Jingsun died of a heart attack and died suddenly. The bad news spread from Washington to Purdue University in Indiana, just as I did with other Chinese who were studying and working at Purdue, could not believe it and could not accept it. Two days later, I participated in the body farewell ceremony and memorial service, very sad. International pattern recognition, artificial intelligence and automatic control science have lost a talented organizer and pioneer, and we have lost a respectable mentor.
