Dr. K. V. Rao: A Legacy of Scientific Pursuit and Human Values

Dr. K. V. Rao, born on March 21, 1920, in Pithapuram, Andhra Pradesh, was a pioneering scientist whose work spanned geochemistry, environmental science, and archaeological chemistry. After completing his D.Sc. in Chemistry at Banaras Hindu University under Prof. S. S. Joshi, he began a remarkable career, first with the Department of Mines and Geology of the Nizam State and later with the Geological Survey of India (GSI). Known for his meticulous planning and innovation, Dr. Rao developed regional laboratories and made groundbreaking contributions in geochemical analysis.
One of Dr. Rao’s notable achievements was his work on defluoridation, which addressed the critical issue of fluorosis in India by discovering Serpentine's ability to absorb fluoride from water. His work had a profound interdisciplinary impact, influencing both scientific and medical fields.
In addition to his contributions to geology, Dr. Rao played a vital role in archaeological chemistry. At Birla Archaeological and Cultural Research Institute (BACRI) he established a laboratory for analyzing archaeological artifacts and spearheaded preservation efforts for heritage monuments such as the Taj Mahal, Charminar, and Ramappa Temple. His environmental studies extended to understanding pollution effects on historic sites and geochemical mapping of river basins.
Dr. Rao’s intellectual curiosity was boundless. He was an esteemed member of numerous scientific societies, a joint convener for international conferences, and an editor for Telugu encyclopaedias. His commitment to science communication led him to publish the “Hyderabad Science News-letter” in the 1960s, bringing the latest research trends to a wider audience.
Beyond his scientific pursuits, Dr. Rao was deeply interested in philosophy, literature, and astrology. A follower of Jiddu Krishnamurti’s teachings, he founded the "Listener’s Club" to foster intellectual discussions in Hyderabad. His knowledge, humility, and ethical approach made him a respected figure, sought after for advice and valued for his compassionate nature.
Dr. K. V. Rao passed away on January 27, 2002, leaving a legacy of scientific rigor, innovation, and a commitment to public service. The Dr. K. V. Rao Scientific Society, established a year before his passing, continues to carry forward his vision of making science accessible, inspiring, and impactful for generations to come.
