Cold Spring Harbor Laboratory P.O. Box 100. Cold Spring Harbor, New York 11724 November 27, 1990 Dr. W. Ronnie Coffman, Chairman Department of Plant Breeding and Biometry 252 Emerson Hall Cornell University Ithaca, N.Y. 14853-1902 Dear Dr. Coffman: Enclosed is the signed endorsement of conditions associated with establishment of the Barbara McClintock Chair of Plant Genetics in the Department of Plant Breeding and Biometry at Cornell University. Not only am I especially honored by the establishment of this Chair but also warmed by this renewed association with the Department. In my junior year at Cornell I took the only undergraduate course in Genetics. It was given in the Department of Plant Breeding. It was fascinating. I must have shown my enthusiasm because I was asked if I would like to take the graduate student course. This course was given in a very different style but it was just as fascinating. I knew then where I wanted to go. May I express to you and to the other members of the Plant Breeding Faculty how very much I appreciate receiving this very special honor. Sincerely, Barbara McClintock Distinguished Service Member Carnegie Institution of Washington
