Dear Bob: I first met Ruiz Ramón when he was teaching at Purdue University. He later went on to University of Chicago, and, I believe, later to Vanderbilt University.
He was a good, penetrating scholar. I have always admired him as a scholar, and he was a fine person, to boot. R.I.P. Joseph V. Ricapito, Yenni Distinguished Professor Emeritus, Louisiana State University, Baton Rouge
