This 696 nm band is now assigned to originate in chlorophyll–protein complex (CP-47) in Photosystem II. George Papageorgiou recently wrote to Govindjee about another interesting topic (photodynamic action of hypericin on cyanobacteria) on which he and Steve had worked together at CB-5083 ic50 Demokritos, Greece in the 1990s (see Papageorgiou et al. 1996; Brody et al. 1997).

George remarked Repotrectinib nmr that during a short visit to his lab, Steve had impressed all his collaborators, and added “Steve was a great scientist, a great guy, a great human being of our times.” Govindjee ends this short snippet of Steve by mentioning that Steve was a very friendly person; he was the only one to call me “Go”, first 2 letters of my name. When I spoke in Hindi on the telephone with my family and friends, he picked up one word “Accha”; it implies “OK” or “good”. In good humor, he would often use it in conversation with me. After receiving his PhD, and after only one semester of lessons from the School of Aviation, at the University of Illinois at Urbana, he obtained his private pilot license. He would rent one of the University airplanes and fly members of the

Emerson-Rabinowitch Lab (as he would put it “those who would dare”) to conferences. Jean Lavorel recently wrote, “I vividly remember that in February, SB525334 mw 1957, we had all gone in an airplane piloted by Steve to Columbus (Ohio) to participate in a Biophysical Society meeting there. It was a fascinating experience”. However, neither Rabinowitch, nor Emerson ever flew with him. I was too scared to fly with him although I did take a short ride once. Joint Research with Marcia Brody GO Marcia Brody was a former PhD student of Robert Emerson, and was also senior to me; she is currently Professor Emeritus of Hunter College, New York. Marcia is an accomplished scientist and had made major discoveries

in the area of two-light effect and two photosystems in the red alga Porphyridium cruentum (see e.g., M. Brody and Emerson 1959a, b). Historically, it is important to point out that G protein-coupled receptor kinase Marcia was a coauthor of an early abstract of a presentation by Robert Emerson (Emerson et al. 1956) that had some of the first hints on what led to the concepts of the two-light effect and two pigment systems of photosynthesis, based on the Emerson Enhancement Effect (Emerson et al. 1957; Rabinowitch and Govindjee 1960; R. Govindjee et al. 1960. (Both Govindjee and Rajni Govindjee were students of Emerson, but became students of Rabinowitch after Emerson died in a plane crash on Feb. 4, 1959.) Steve Brody collaborated with Marcia (see Biographical Portrait below) extensively since 1959 for a little more than 10 years. We mention only a few of their collaborative studies here. This collaboration included studies on dynamic changes in the efficiency of excitation energy transfer (Brody and Brody 1959; M.
