Dear Dr. Lederberg:

The Southwestern and Rocky Mountain Division of the American
Association for the Advancement of Science will meet at the University
of Arizona, Tucson, Arizona, from April 28 to May 2, 1957. One of the
outstanding events of the meetings of this group is the John Wesley
Powell Memorial Lecture given by a distinguished investigator in some
field of science upon a topic of his own selection. This lectureship,
established in 1929 by an anonymous donor, provides an honorarium of
$150. There is no additional expense allowance.

Since the meetings more or less coincide with the opening of the
new Biological Sciences Building and since the list of Powell lecturers
has never included a microbiologist, it seems appropriate that this
years lecturer should represent that field. As chairman of the Powell
Lecture Committee, it is my privilege to invite you to participate as
this years lecturer. The lecture date is Tuesday, April 30, at 8 P.M.
but this could be changed to Monday, April 29, if the lecturer so wished.

We would be grateful for an early reply and, if you accept, for the
subject of your lecture.

Sincerely yours,
