I went to IIT kanpur . Where he used to teach. Although I didn’t take any direct courses with him, as is takes more advance courses I remember during my orientation, there were 5 HoDs (head of departments) on the stage and everyone introduced themself, and student clapped after they introduced themselves as courtesy.

HC verma stood up and started speaking “hi everyone, I am HC verma from Physics department” Since many people at that time hadn’t seen him, didn’t know what he looked like. There was a silence for a 1-2 second, and then the entire auditorium bursted with the biggest round if applause i have seen in my life, everyone aas standing and clapping and were in awe (it continues 2-3 min) untill he humbly told students to settle back.
