1980年仲夏,著名考古学家贾兰坡教授带领了一行地质、古生物科考队员,冒着蒸腾的暑热,风尘扑扑地来到了宁夏灵武境内的水洞沟.贾老停步在一所房屋的断壁残垣面前,想起了科学史上一位难忘的过客.就在这家“张三小店”里,曾经居住过世界著名的古脊椎动物学家、中国人民的朋友德日进.来访的人们怀着崇敬的心情,怀念着这位长期在中国探索大自然,并做出了重要贡献的法国学者. In mid-summer 1980, Professor Jia Lanpo, a well-known archaeologist, led a group of geological and paleontological expedition members who came to Shuidonggou in Lingwu territory of Ningxia braved the heat of transpiration. In front of the ruins, I remembered an unforgettable guest in the history of science, where I once lived in the world-famous ancient vertebrate zoologist and friend of the Chinese people, Germany and Japan. With respect and reverence, the visiting people miss the French scholar who has made long-term exploration of nature in China and made important contributions.
