I was Jason’s first graduate student. Princeton was a very exciting place when I arrived in 1966. There was lots of discussion on how sea floor spreading might work. Jason, was hard at work demonstrating Fred Vine’s lineations meant plate tectonics. And yet somehow he found time to take on a graduate student. He was an ideal advisor, never intruding too closely in day to day work, but always available for questions, and always clear and thoughtful in discussions. We became good friends, and I later spent many fascinating visits with his family in their small apartment next to campus. Time has passed far too quickly, and it is very hard for me to believe that Jason will no longer be there for discussions and suggestions. A great many people will miss him very much, and I am certainly included in that very long list.
