Washington DC: American CHemical Society, 1991. First Edition. Octavo. Blue cloth boards; 143pp. Fine copy, inscribed by the Nobel Laureate on half-title, undated but apparently contemporary: "To Maurice and Kitty / in memory of many hapy and creative days - and of wonderful hospitality." Barton (1918-1998) shared the 1969 Nobel Prize in Chemistry. The recipients are the Harvard endocrinologist Maurice Pechet (d. 2012), with whom Barton collaborated on some of his most important work in the early 1960s, and his wife, the artist/educator Kitty Pechet.
