Eugene Plotkin

I believe Eugene Plotkin has died. I read this on the AGTA website but I have no details. I met him for the first and only time at Daniela Nikolova’s birthday conference in Deerfield Beach, Florida, four years ago. We got on very well. Outside of mathematics, one of his hobbies is finding beautiful “works of art” in natural stones; he sent me some of the extraordinary videos he had produced.
