He’s not dead! In fact, he’ll turn 91 on September 14. Here are some links:

Interview with director Robert Hupp in 1996

NY Times on his life and legacy.

I hate them! They should at least let you watch a commercial like Salon to get to the article.
Wikipedia bio.

I do think Upstage needs a “dead or alive” feature.
