Jan 11 1982 Re: Bonner family archives I was so pleased to see this note in the AIP/CHP newsletter. It was very distressing to hear from UC/SD Biology a few years ago that they had "lost" David M.'s papers after a desultory effort to preserve them.

I would be much obliged for your help. Sincerely, Josh Lederberg
