Dear Dr. Lederberg:

Would you join me in signing the attached communication addressed
to the President of the United States and intended as an open
letter to him.

This expression of our support, I have reason to know, will be
welcomed by him. Further, our suggestions may serve as a needed
incentive to action which may bring the American people to support
a test ban treaty.

The President and his principal advisors in the Defense and State
Departments, as well as the Security Services, are of the unanimous
view that a test ban treaty with on-site inspection is in the
national interest. Further, that once enacted, it may be a vital
first step toward disarmament.

A two-thirds affirmative vote of the U. S. Senate is required to
approve any U. S. treaty. At this writing, passage of a treaty
if negotiated with the USSR, is doubtful. Congressional mail
indicates opposition or apathy.

Many things are responsible, chief among them inadequate knowledge
on the part of the American people of the perspectives for security,
development and peaceful co-existence which would open up in conse-
quence of this vital first step.

What we do now may be decisive for the future.

If, as I hope, we share a common view on this critical issue, will
you authorize me to include your signature.

Sincerely yours,

Let le dpe
