Bernie,
It was a yeoman's task which you accepted and I congratulate you for your work and keeping us informed. One other skill Jon had was that of an artist. I recall being enrolled in an after school art class conducted in Leonia by a local artist at her studio. I sat next to Jon and watched him sketch the still life with such fluidity and aplomb as I sat there trying to sketch the same still life. The final result: mine looked like day old spaghetti and his was a masterpiece. That's the underlying attribute he possessed: he made everything look so easy.
