"My father had an older friend who was a retired mathematics professor. His name was Leopold Klug, and he is probably the man who had the greatest influence on my life. He was a retired mathematics professor, and he got me a book. Algebra by Leonhard Euler. I was ten years old. The problems that came up were too difficult for me to solve, but not too difficult to understand. Klug gave me that book and I read it. It was my favorite book. Klug was the first grown-up whom I met who loved what he was doing." -- Teller
