Dear Peter:

We have Just recelved notice of the Symposium program In San Francisco
on which your name Is listed for 19 October.

Now that you will have found yourself so far west, can | possibly per-
Suade you to take a few hours for a visit to Stanford? There are any
number of people here who would be most anxious for an opportunity to
hear from you and who may not find It possible to come up to the city
on Saturday afternoon. 1 hope this suggestion Is congental to you,

but if your schedule is overburdened and you would prefer making your-
self available more Informally to a half dozen or so people who are
anxious to see you, this would also be an event of great pleasure. Or,
finally, If your trip witt heve gotten you to the point where you Just
don't want to see anyone else, | hope this does not go so far as to
prectude even a more private social confluence for an afternoon or for
dinner at our home. In any case, | hope one of these does meet your
pleasure, as It certainly would ours, and that 1 do not write you too
late to enable you to fit this Into your plan. If you will let me
know by mall or by phone at your own convenience, we will accomodate
however possible. 1 do look forward to seeing you and hope this will
be for more than the limited possibility afforded by the maeting itself.

| suspect that you were going to say thet genetics has very little to

do with the future of man, at least In the sense of what | Judge to be
Our consenses at the Ciba Symposium. However, It just occurred to me
that vegitative reproduction may be In the offing much sooner than most
people would have suspected -- along the lines of nuclear transplantation
Into eggs -- and If so, this might have a bearing on the genetic compo-
sition as well as the developmental outcome, Within the time scale of
the future that Is worth discussing.

Cordially,

Joshua Lederberg
Professor of Genetics
