His students remember his endearing personality and habits. “He used empty envelopes left from incoming mails for writing research papers. He almost never used normal paper or notebook to write down,” Singhi recalls. “As a chairman, he used to get a lot of mails. He had developed his own techniques on how to open an envelope of incoming mail carefully so that its inside could be used to write mathematics. These covers which most people throw away were the ones which carried most of Shrikhande’s research work, with me and with others.”
Fascinating!
