October 10, 1990 Dear Doctor Nirenberg: I have received the attached letter from Dr. Norbert Perrimon asking me to join in the continuation of a chain letter supporting the demand to abolish apartheid in South Africa. This letter has been initiated by Dr. M. Mboya, Department of Education, University of South Africa, Private Bag, Rondebosch 7700, South Africa. I am very willing to express my commitment as a scientist in the promotion of human rights and civil liberty. I am accordingly asking if you would do likewise. If so, please write ten other scholars whom you know personally and ask them for a similar letter of support with a copy to Dr. Mboya. Sincerely, Mark C. Fishman, M.D. Enclosures: CC: Dr. M.
