I learned from SymOmega that Dan Hughes died yesterday.
I owe a huge amount to Dan. He invited Jack van Lint and me to lecture at Westfield College in the early 1970s and encouraged us to publish the lecture notes, which have now evolved into the student text Graphs, Codes, Designs and their Links.
Then in 1986 he persuaded Queen Mary College, London, to offer me a position to tempt me away from Oxford. And here I am still.
In September 2008, I spent a couple of weeks in Rome; Rosemary Bailey, Dina Ghinelli and I visited Dan at the farm where he lived in Valcelle, near Torrita di Siena. He took great pleasure in showing us around the countryside, taking us to places off the main tourist trail.
He is much missed.
