[Sorry if this isn't quite the usual business for this list.]

I've been wanting to get in touch with my old X3J13 colleague JonL White, but email to his last known good address got no response. He is one of the important contributors to Lisp development over the past half century. I believe he is still somewhere in the silicon valley area, but he has had health issues the past several years. Anyone have recent news or contact information?

TIA--
