This is George Berszenyi.
He was the Chairman of the Department of Mathematics at my alma mater, Rose-Hulman Institute of Technology, while I was a student there majoring in mathematics.
I took but one class he taught. I forget after 30 years which one it was. I remember him as a kind man, genuinely interested in each of his students.
He was profiled on NPR recently for mentoring young mathematicians, challenging them through interesting problems to grow in the field. Several of the young people he coached went on to great things in mathematics and engineering. Read the article about him here.
I have a funny but embarrassing story to tell about George Berszenyi. My alma mater’s tradition is that the Chairman of each department read the names of that year’s graduates in each major. My full name is James Wilson Grey, III. In his thick Hungarian accent he read it as James Vilson Grey the Turd.
Titters went up from all corners of the audience. I crossed the stage red-faced.
