I am the Centennial Historian of Rice University. This means, among other things, that every day when I go to work I am surrounded by people who are smarter than I am.

He was a brilliant student, an accomplished chemist and so on, but the combination of his lived experience and his lifelong intimacy with the Torah gave him something beyond the grasp of most of us.

He was a teacher and a learner, honest in his inquiry into the past and always hopeful for better things to come.
