Giants in History: Clara Lim-Sylianco

The chemist dedicated to education 

Clara Lim-Sylianco (18 August 1925 - 23 July 2013)


Eminent Filipina scientist and educator Clara Lim-Sylianco (18 August 1925 – 23 July 2013) is remembered for her extensive research on mutagens – often-carcinogenic agents that permanently alter genetic materials such as DNA – antimutagens and bioorganic mechanisms. She also wrote many chemistry textbooks, some of which remain in use today. Drawing on both organic chemistry and biochemistry, Lim-Sylianco’s research advanced the understanding of specific areas of study including environmental mutagens and the mutagenicity of medical plants found in the Philippines. She published over 50 scientific articles, seven books and five monographs on research encompassing organic chemistry, biochemistry, genetic toxicology and molecular nutrition. In 1958, Lim-Sylianco became a Fellow of the Royal Society and in 1977 she received the Philippine Association for the Advancement of Science and Technology’s Gregorio Y. Zara Award. Lim-Sylianco was also recognised as a National Scientist of the Philippines, the highest award accorded to Filipino scientists by the Philippine government.
