**Mathematician Walter Lederman**

Not all mathematicians get written up in the history books.

I never thought about it, but I suppose that Walter Lederman was the first professional mathematician I knew. I met him during my first year at the University of Sussex in the UK.

It was in 1967. He taught number theory and group theory. Students loved him. Not sure why. Perhaps it was because he had an enthusiasm for his subject. In group theory he recounted the exploits of Evariste Galois like he know him personally. He was real. He gripped his students. He was also very low key. Thanks Walter. I did not forget.
