Memories and Condolences

Ronald was one of several graduate students that I advised, when I was an assistant professor in the Department of Biology at University of Southwestern Louisiana during 1964-1967. I also knew his future wife, Marilyn Barrios who was a student in the Microbiology Department at USL at the time. I stayed in contact with both of them, from time to time after that. Both were outstanding students and were highly successful in their chosen profession.

I remember him well, he was my major professor while at Nicholls. Many good times spent on field trips through the swamps with him. He has never been far from my memory.

Pepper and Rader Jackson send their deepest sympathies on Ron's passing. It is very sad being so close to the entire Esteff DeFelice family for so long starting with Ron's grandmother and all of her children. I did have the opportunity to express my prayers to Ron personally about a month ago. God bless Ron and his family.
