JUL 25 Woy MEMO FROM TO: J. LEDERBERG RC GENETICS DEPARTMENT Dean Teller RO STANFORD UNIVERSITY STANFORD, CALIFORNIA ‘Te wanes of 7/10 . Thank you for this amplification. It was when I found that I could not convey my thinking effectively via even the best science news men that I decided to write on my own-- and even then...» This note gives me an opportunity to ex- press my gratitude for a adam debt I have never known how to repay. The Cooper Union library was a vital source of my own educa~ tion, when I was a student at Stuyvesant H.S (1938-41). I have a very happy recollection of having been treated with the utmost con- sideration when I was devouring the contents of its stacks, learning chemistry and mathe- matics on my own schedule -- and when I might well have been rebuffed or ignored, as often happened at other institutions. Yours sincerely, po AS. x Pires . Eye : Sar (Yt Cty)
