We present here a tribute to George E. Hoch, one of the top leaders in deciphering the primary steps of oxygenic photosynthesis. After providing his academic background, we discuss his selected research on the photoreactions of photosynthesis. We end this tribute with reminiscences by Robert S. Knox, Jerome Kaye, and Doris Teichler-Zallen.

Additional key words: Bessel Kok; Louis N.M. Duysens; RIAS (Research Institute of Advancement of Sciences), Baltimore, Maryland; University of Wisconsin at Madison.
