He (my brother) liked to do experiments. He would collect all kinds of equipment — electricity, chemicals from the drug store. Occasionally, somehow he’d get hold of a chemistry set, and we had a flash of opulence. And he loved to do things, and he’d make things work, and I loved to watch him, and I think that was a strong influence on me. It sort of introduced me to things and how they work, and that was impressive. So I think that he probably disposed me toward chemistry, and in high school the chemistry teachers were more fun. So there I was a chemist.
