March 2, 1965 The Honerable John E. Fogarty House of Representatives Washington, D. C. Dear Congressman Fogarty: Dr. Ralph Knutti of the National Heart Institute called me to ask whether I could contribute a statement to the hearings before your committee concerning system development on the mechanical heart pump. As I had taken my own initiative some while ago to urge exactly what the Institute now proposes, I am in full support of this program. I regret it would be awkward for me to leave my duties here for a personal appearance. However, I doubt if I could contribute much more than I have written down for the statement enclosed. With cordial best wishes and appreciation for your long-standing personal interest in problems of medical research, Sincerely yours, Joshua Lederberg Prefessor of Genetics be: Dr. Ralph Knutti
