I had the distinct privilege of briefly meeting him and his late wife Jeanne back in '06 at the D.C. Book Fair.
He autographed a first print copy of "Antinomy" for me, acknowledging then that it was rare.
I had purchased it new in October of 1980, when it came out.
I had “Antinomy.” Paperback. In the early 80s, when I was still in high school.
