A grandson of Singapore pioneer and philanthropist Lim Boon Keng, he gained worldwide fame in 1957 when he isolated the flu virus during the Asian influenza epidemic.
A lover of the arts, Prof Lim founded Centre '65, a multiracial arts group which held talks and staged plays, such as adaptations of Singapore writer Goh Poh Seng's works.
He was also an active champion of chess, and helped make the game popular here.
He won Singapore's first national chess championship in 1949 and set up the Singapore Chess Federation, which he led for 18 years. From 1982 to 1988, he was secretary-general of Fide, the World Chess Federation.
