366. SCIENCE AND MEDICINE An unusual collection of twenty-one letters from leaders in the advance of scientific knowledge and medical technology. Includes: CHRISTIAAN BARNARD South African physician who performed the world's first successful heart transplant. Five T.L.S. "Chris" [4] and "Chris Barnard" all on University of Capetown letterhead, 5pp. 4to., dated from May 23, 1972 to Dec. 1, 1976, to Sylvia Lyons (wife of NY Post columnist Leonard Lyons) : "... I have had many offers since the first heart transplant but have decided...I should not move, as money has never been a great attraction for me..." Most letters express sympathy regarding Leonard's deteriorating health and in the last, the great surgeon writes: "It was with great distress and sorrow that I heard about the passing away of dear Lennie..." Some marginal tears and wear. KARL MENNINGER Influential American psychiatrist who advocated violence-free parenting, altruism, and the building of self-esteem as keys to mental health. Ten T.L.S.'s "Karl Menninger" [7] and "Karl", 10pp. 4to, New York and Topeka, April 29, 1939 to Feb. 20, 1970, to Leonard Lyons. In part: "In a picture of Hitler making his speech, published by the Journal American Friday, a man in the back row is yawning unmistakeably. I suppose he will get the guillotine... In your column recently, you gave a boost to Dr. Manfred Sakel, whom you called a 'famous psychiatrist.'... He is not a psychiatrist at all, and the treatment he introduced for the kind of mental sickness from which [ballet legend Waslaw] Nijinsky suffers is being increasingly discredited, in spite of the fact that it had a big plug in 'Reader's Digest' this month... this article said that the treatment cured seven out of ten cases... To encourage heart-broken relatives... that a terrible disease can usually be cured by the 'expensive' treatment of a famous (?) refugee 'psychiatrist' is a cruel and bitter thing to do... [stage mentalist Joseph] Dunninger. He's quite a showman, isn't he? But I share your skepticism." One letter lacks it first page, mounting traces to two letters, overall age toning, in good condition. HOWARD A. RUSK American physician, considered the father of rehabilitative medicine. Five T.L.S. "Howard" [4] and "Howard Rusk, Jr.", 5pp. 4to., New York, Jan. 21, 1959 to May 28, 1964, to Leonard Lyons. In part: "...I wanted to thank you... for lending your assistance tin getting Mr. [Jose] Ferrer to attend. The ladies on the committee were delighted that he could come and he certainly added to the evening..." All are in very good condition. GREGORY SILBOORG American psychiatrist and psychotherapist; a committed Catholic, he rejected the atheism of Freudian psychoanalysis. T.L.S. "Gregory Zilboorg" on his imprinted stationery, 1p. 4to., New York, April 9, 1945, to Leonard Lyons. He write to Lyons about the latter's "note about [Hungarian playwright] Ferenc Molnar, who told something about himself that puzzled me..." and apparently accuses Molnar of exaggeration by relating a story once told about Abraham Lincoln to Gen. George McClellan regarding overestimates of Confederate troop numbers. Lot also includes two additional items, an A.L.S. and a T.L.S. by individuals we were not able to identify. $500-700
