Money and materials alone do not secure good research, they are only adjuncts and it is the human element behind them that matters, said T. R. Seshadri.
Seshadri was born on 3 February 1900 at Kulithalai, an ancient village with history dating back to the Cholas of the 9th century CE, in the present-day Karur district of the south Indian state of Tamil Nadu, in a Brahmin family, to Namagiri Ammal and Thiruvengadatha Iyengar, a school teacher, as the third of their five sons.

After graduation, he worked with the Mission for a year, but continued his studies at Presidency College for his master's degree and thereafter, for research under the renowned chemist, Biman Bihari Dey, during which period he won two research awards, the Curzon Prize and the William Wedderburn Prize, from the University of Madras. He secured a scholarship from the state government in 1927 for higher studies at University of Manchester where he did his doctoral research under the guidance of the renowned British chemist and Nobel Laureate, Robert Robinson, to secure a PhD in 1929.
