Extractions: In the spring of 1959 I received an offer of a Professorship at Harvard, which I accepted with alacrity since I wanted to be near my family and since the Chemistry Department at Harvard was unsurpassed. The Harvard faculty in 1959 included Paul D. Bartlett, Konrad Bloch , Louis F. Fieser, George B. Kistiakowski, E. G. Rochow, Frank H. Westheimer, E. B. Wilson and R. B. Woodward , all giants in the field of Chemistry. Roger Adams, who was always very kind and encouraging to me, gave his blessing even though years before he had declined a professorial appointment at Harvard. I have always regarded the offer of a Professorship at Harvard as the most gratifying of my professional honors.
