I was lucky enough to have John Dizikes as my senior advisor in 1968. John was erudite, humorous, and approachable. From him, I learned to be critical in judgment and always find a laugh. He was fond of irony. Like Page Smith, his teaching focused on individuals - how people lived and what their personal lives taught about their times. He wrote about what interested him. I learned that following your passion for the past was okay - it was and is a good enough reason to study history. In so many ways John Dizikes enriched my life. May each of us find a mentor like John.
