Also, he is supposed to be honored at an upcoming awards ceremony on
10/14.  The organizer's information is here, she may be able to pass

Direct phone lines and personal email addresses of famous people are,
for obvious reasons, not generally available. If info about such a
thing leaks out, the phone number and the email address is likely to
be changed immediately, to avoid a flood of nuisance calls and
messages.
