title: Bill Arnold: Scientist, philosopher, friend.
abstract: Bill Arnold is a great scientist in whose laboratory I was privileged to work during the years he discovered the thermoluminescence and the electroluminescence of green plants. I reminisce about Bill's influences on me, scientific and otherwise, during those years.
