I am stunned and saddened to learn of Deans passing. I was in college with Dean at Tulane and he was among my closest friends then and thereafter. He was at my daughters weddings in 2014, and I saw him at another college friends daughters wedding about two years ago. Reading the tributes, it is clear Dean never changed. He was fun, kind, generous, unassuming, diligent and intelligent. Based on our discussions, he loved his job, students and colleagues. And, his dogs fit in somewhere among the upper tiers of people and things that were dear to him. Even within the more recent years as he fought his cancer, we never once spoke when we did not laugh so hard we both cried. Dean, you will be missed.
