Lin K'o-sheng (15 October 189 7-), known as Robert K. S. Lim, was the eldest son of Lim Boon Keng Lin Wen-ch'ing). A renowned physiologist, he served as professor of physiology at Peking Union Medical College (1924-37), director of the Chinese Red Cross Medical Relief Corps (1937-42) and the emergency medical service training school (1938^2), and surgeon general of the Chinese army (1945^8). He went to the United States in 1949. In 1952 he joined Miles Laboratories, becoming director of medical sciences research in 1962. The eldest son of Lim Boon Keng (Lin Wen-ch'ing, q.v.), Robert K. S. Lim was born in Singapore. His native place was Amoy, Fukien. After completing his secondary education in England, Robert Lim followed his father's example by entering the L'niversity of Edinburgh. He interrupted his studies during the First World War to serve in the British Army, attached to Indian troops. After returning to Edinburgh, he received the M.B. and Ch.B. degrees in 1919, became a lecturer in histology in the physiology department, and obtained the Ph.D. degree in 1920. That year, he was named a Goodsir Memorial Fellow. He remained at Edinburgh until 1923, when he was awarded a Rockefeller Foundation fellowship for a year's study at the University of Chicago. In 1924 he received the D.Sc. degree from the University of Edinburgh and returned to his native land to become professor of physiology at Peking Union Medical College, a post he was to hold until mid-1937. Beginning in the 1920's, Robert Lim published reports of his research activities in Chinese, British, and American journals of physiology. He founded the Chung-kuo sheng-li hsueh-hsi [Chinese physiological society] and served as managing editor of its journal from 1927 until 1941, when it ceased publication. He was president of the Chung-kuo i-hsüeh hui [Chinese medical association] in 1928-30 and field director of the Chinese Red Cross Medical Relief Commission in north China in 1933. In 1936 he became chairman of the Hua-pei nung-yeh fu-hsing hui [north China council for agricultural reconstruction] and a counsellor of the Academia Sinica.

In the Autumn of 1937, Lim, who was on his way to Europe for a sabbatical year, was called to Nanking. When the National Government evacuated the city, he took charge o( the remnants of the Chinese Red Cross and organized the Chinese Red Cross Medical Relief Corps. He served as its director until 1943 and, under his direction, the corps set up a medical supply system to assist the army, sent more than 100 medical units into the field, and created a unit of more than 200 ambulances which saw service on all fronts. In 1938 he established the Chan-shih wei-sheng-jen yüan hsün [emergency medical service training school] to train medical personnel for the civil relief services and the army. By 1942 the school had expanded to include a central school at Kweiyang and five branch schools in different war areas. It has been estimated that more than 13,000 people received training in these schools. From 1942 to 1944 Robert Lim served under General Joseph Stilwell as medical inspector general of the Chinese expeditionary force in Burma. In May 1942 he led the remnants of Chinese military hospital staffs from Mogaung to Ledo. He became deputy surgeon general of the Chinese army in 1944 and surgeon general in 1945. After the war ended in 1945, he continued in this post so that he could rehabilitate the medical service. He organized the Kuo-fang i-hsueh yuan [national defense military center] and initiated a program which provided Chinese medical personnel with postgraduate training in the United States. In 1948 he was asked to become minister of health in the National Government, but he declined the offer and retired from his military post. Robert Lim went to the United States in 1949 to become visiting research professor of clinical science at the University of Illinois in Chicago. From 1950 to 1952 he served as chairman of the department of physiology and pharmacology at Creighton University Medical School in Omaha, Nebraska. He then joined Miles Laboratories, Inc., in Elkhart, Indiana, as head of physiology and pharmacology research and became director of medical sciences research in 1962.

Among the many scientific papers published by Robert Lim are a number of special studies in gastric histology and pharmacology, including the results of extensive research on sedatives, hypotensives, and analgetics. As a military man, he was decorated by the Chinese, British, and American governments; as a scientist he was named to honorary membership in several foreign - academic and professional societies. In 1961 the University of Hong Kong awarded him an honorary D.Sc. degree. Robert Lim married twice. His first wife, Margaret (d.l936), was English. They had two children, Euphemia (1923-) and James (^1927-). Lin married Chang Ch'ien-ying, the daughter of Chang Jen-chieh i,q.v.), at Shanghai in 1946.
