I always admired Bill since he was such a thinker who persevered and solved complex problems like the mechanism of photorespiration that clearly is a landmark discovery. His

approach was the key to being a great scientist and the awards he has won, including this one, have been justly deserved. Along the way he also helped nurture a group of very astute researchers. George Bowes As noted in the write-up by Archie Portis (see Ogren and Bowes 1971; Bowes et al. 1971), the first observation that gave the idea that the same enzyme (known earlier as “carboxydismutase” in Melvin Calvin’s lab) was responsible for reaction with CO2 and O2 evolved in the work of Bill Ogren with George Bowes, who was a postdoctoral associate at the University of Illinois at Urbana, Illinois. Although George was unable to this website attend the ceremony, he was invited by the two of us to present his story. George

sent the following text to us. It reads: I was Bill’s first postdoc. I came to the US in 1968 at Richard (Dick) Hageman’s invitation, but when I arrived he gave me a choice—to work on nitrogen metabolism or work with Cell Cycle inhibitor a “young USDA scientist” (Bill Ogren) on photosynthesis. Knowing little about either topic I asked for a week to decide and Bill gave me some papers, including one by Olle Björkman that contained Chorioepithelioma a graph showing carboxydismutase (Rubisco) activity was directly related

to photosynthesis rate. It convinced us both that this was an important enzyme, and could be a productivity “marker” in soybean varieties—a topic we pursued prior to purifying the enzyme and investigating its kinetic characteristics.   Working with Bill was an enjoyable and productive learning experience. Coming from a largely self-directed PhD program, I appreciated being a collaborator, not someone to “direct”, and this laid-back leadership style of his has produced some remarkable scientists and discoveries. Bill was easy to talk with, very prescient and AZD2281 purchase direct and could take a half-baked idea and hone it into something useful. I recall Friday afternoons when we would chat about everything from English customs (Bill was an anglophile) to politics and sports. This Englishman/American learned a lot about American life from Bill. Inevitably, the talk turned to the recent discovery of C-4 photosynthesis and the mechanism of the Warburg effect (Warburg 1920). These casual conversations were some of the most productive times of sharing ideas to test experimentally. Later Bill Laing and then Ray Chollet joined the lively prolonged coffee hours.   I am thankful that neither Bill nor Dick gave up after the first year of research when I had no publishable results to report, and was quite discouraged.
