Put simply, Professor Ranganathan was a legendary teacher, educating and inspiring, both!!! His books ‘Art in Organic Synthesis-Part-I and Part-II’ were referred to in the Nobel Prize lecture of E. J. Corey. Woodward also cited these books in his lectures. His other book ‘Fascinating Problems in Organic Reaction Mechanism’ has been used by organic chemists of many generations, all over the World. Almost always dressed elegantly in blue, a master of the English language, Ranga was held in such a high esteem by the students that his mere sight was considered motivating! Ranga liked to dress in blue to emulate his pos-doc advisor, the legendary synthetic chemist R. B. Woodward. Ranga had a picture of Woodward in his office nicely portrayed on a board, just next to his desk; sight of this was stimulating to anyone passing by Ranga’s office, on the fourth floor of the faculty building. Ranga’s passion for chemistry was both inspiring and contagious. Over the course of about three decades at IIT Kanpur, his inspiration helped launch successful careers in chemistry of countless students, who ever came in contact with him.
While I was writing my thesis (1978), I used to visit Ranga’s house in type VI, where Ranga, Darshana, and I used to work until late at night. This routine continued for weeks until the thesis was all written up and sent out to examiners. I wonder if Ranga had any other interests besides chemistry.
