I spoke to Julius Schwartz this evening. This was not easy to do as his hearing is bad, though it is expected to improve. I did manage to make him understand that I'm mailing him a few hundred "Get Well" wishes from his fans on the Internet. He was concerned because he has no way to respond to them but I assured him you didn't expect replies.
You can still send mail to schwartz@newsfromme.com but please…don't ask questions that he'll feel should be answered. And no attachments.
