his lectures were legendary and frequently used to last for three or four hours. [his longest known lecture defined the unit of time known as the "woodward", and thereafter his other lectures were deemed to be so many "milli-woodwards" long!] in many of these, he eschewed the use of slides and used to draw beautiful structures by using multicolored chalk. as a result, it was always easy to take good notes at a woodward lecture. typically, to begin a lecture, woodward would arrive and lay out two large white handkerchiefs on the countertop. upon one would be four or five colors of chalk (new pieces), neatly sorted by color, in a long row. upon the other handkerchief would be placed an equally impressive row of cigarettes. the previous cigarette would be used to light the next one. his famous thursday seminars at harvard often lasted well into the night. he had a fixation with blue, and all his suits, his car, and even his parking space were coloured in blue. in one of his laboratories, his students hung a large black and white photograph of the master from the ceiling, complete with a large blue "tie" appended. there it hung for some years (early 1970s), until scorched in a minor laboratory fire. he detested exercise, could get along with only a few hours of sleep every night, was a heavy smoker, and enjoyed scotch whisky and a martini or two. hoffmann would correspond with woodward using blue paper.
