I guess I only knew of him as in the Backus-Naur form. A trivial idea almost, but the best ones always are, after someone else has had them.
He got his masters degree when I was two years old. I didn't realise he was that old.
Strangely, I put up two pictures of punched cards here, on Saturday, the day he died.
