今年三月三十日是中国人民的挚友,国际感光科学委员会前主席W.F.Berg教授诞辰八十周年纪念日。他虽然离开我们已经三年多了,却永远活在我们的心里。Berg教授不仅是一位学识渊博,经验丰富的学者,也是一位和霭可亲、平易近人的长者。他对中国人民怀有深厚的情谊。在接受中国科学院名誉教授证书时,他曾满怀深情地说:“我晚年的活动能够同十亿伟大中国人民的事业联系在一起,这对我是无上的荣耀”。他十分珍惜这种情谊,因此,他传授知识、介绍经验、提出建议、给予批评,无不真心实意地从中国人民的利益出发,为中国长远的发展着想。 March 30 this year is a close friend of the Chinese people and the 80th anniversary of the birth of Professor W.F. Berg, the former chairman of the International Photo Science Committee. Although he left us for more than three years, he lives in our heart forever. Professor Berg is not only a knowledgeable and experienced scholar, but also a happier and approachable elder. He has a profound friendship for the Chinese people. When accepting the honorary professor certificate from the Chinese Academy of Sciences, he once said with deep feeling that “my later years activities can be linked with the cause of one billion great Chinese people. This is a supreme honor to me.” He cherished this friendship very much. Therefore, he imparted knowledge, introduced his experience, put forward his proposals and criticized him. He always sincerely considered the long-term development of China from the interests of the Chinese people.
