Gerry is right, and I was wrong.

The Boston Globe obituary printed no birth year, but gave Mouradian's age as 66; I got 1951 by subtracting 66 from 2017.

His first posthumous birthday will be here soon.
I wonder if the New Englanders who knew him will make a public event of it. Although this thread does not show it, he was known and revered, even loved, by many, who think him irreplaceable.
