He was very much involved after I left in editing books. I would come and when I visited Cold Spring Harbor for meetings I would go up and visit him in his home. He was at the time-early on he was doing things like making wine and I remember he gave me a bottle of dandelion wine that he had made. And I could not bring myself to drink it because it was so very precious. So I saved this dandelion wine for many, many years until ultimately of course it was no longer drinkable. I had to toss it out. He was really extraordinary.
