In Memory of Dr Upatissa Pethiyagoda

Dr Upatissa Pethiyagoda passed away on 27 August 2026 at the age of 94, leaving behind a rich legacy as a distinguished scientist, accomplished administrator, diplomat and public intellectual. Born at the Trinity College, Kandy, he obtained a first-class in Botany and pursued postgraduate studies in London. His scientific career was marked by an enquiring and restless mind that continually questioned the accepted norms.

During the 1970s, he headed the Plant Physiology Department at the Tea Research Institute of Sri Lanka, where he played a significant role in the development of the tea industry. Later, at the Coconut Research Institute, he not only expanded his expertise in plant physiology but also delved into other scientific domains. Dr Pethiyagoda's ability to connect knowledge from various contexts into practical solutions was truly remarkable.

His communication skills were equally impressive as he was an eloquent speaker, often lacing his speeches with wit, humour, and occasional tongue-in-cheek remarks. Despite his humorous tone, his opinions were always forthright and he was not afraid to express them, even when faced with potential repercussions. He was a vocal advocate for scientific and evidence-based decision-making and was deeply concerned about the consequences of certain government decisions on farmers.

Throughout his life, Dr Pethiyagoda's curiosity remained unquenched. Even in his 90s, he continued to ask questions, pursue ideas, and seek answers. His interest in genetic differences between varieties of jak, and the potential commercial application of wela variety for cellulose extraction, showcased his continued passion for scientific inquiry. Even as Ambassador to Italy, he remained focused on making significant contributions to FAO discussions and entertaining Sri Lankan Ministers of Agriculture.
