134. From Felix Frankfurter
Cambridge, Mass., 17 May 1921
Esteemed Professor Einstein,
I am sorry to bother you but truth compels me to do so. I am told that Dr.
Levin[1]
—and through him probably others as well—accused me of having wanted
to prevent your appearance at Harvard for lecturing or for any other
purpose.[2]
This accusation is absolutely untrue. I simply cannot understand why people stoop
to such unforgivable slander. But such is, in fact, the case; and that is why I am
compelled—painful though it is for me—to write this denial. May I hope that it was
superfluous—that you did not believe it, anyway?
In great respect, yours sincerely,
Frankfurter.

136. To Ludwik Silberstein[1]
[New York,] 21 May 1921
Dear Mr. Silberstein,
First of all, I would like to say once again how happy I am finally to have made
your personal acquaintance and that our time together was a great pleasure for
me.[2]
The experiment you are planning is, I am convinced, of very great interest for
the special theory of relativity. I thought about the matter again in greater depth and
came to the conclusion, in full agreement with yours, that according to relativity
theory, or Lorentz’s theory, a positive effect must
result.[3]
It is very desirable that
the experiment be conducted with the best of means, and it is lucky that the master
Michelson wants to conduct
it.[4]
Pardon my brevity—my present situation does not permit otherwise. Cordial
regards, yours,
Einstein.
