Daniel Holz was one of those students lucky enough to work with John Archibald Wheeler:

For two years I sat at the feet of the master, and I absorbed as much as I could. I learned about science, and about life. Wheeler had broad interests. We would often discuss biology, or history, or poetry. Over the ensuing years we kept in touch. We collaborated together on Wheeler’s last published paper.

Yesterday I spent a couple of hours at Wheeler’s bedside. I tried to say thank you. But it was impossible to convey how much he means to me, and how grateful I am to him. In that moment when I crossed the threshold to his office, I was embarking on a new path. I am still on that path, and every day I am grateful to him for showing me the way.

John Wheeler died this morning.
