Thanks for making this post. Ricky and Branko died (at 83 and 88) within a week of each other, and I was greatly fond of them both.

I knew Ricky through being a co-founders (with Erwin Lutwak and Eli Goodman) of the Courant Geometry Seminar, of which Ricky was the guiding light for so many years. This seminar was a “dinner seminar,” and I probably had more meals in the the company of Ricky that I did with anyone else other than my family.

Without Branko (and my thesis adviser Donald Crowe) I would not have the career I did as a mathematician. See my comments here:

Branko was generous with his ideas and time over many years, and nearly all the mathematics I think about was inspired by his work.

I will miss, as will the mathematics and geometry community, these extraordinary men.

Regards,

Joe
