I provide here both my personal and scientific autobiography. After giving a background and summary of most of my research, I present information on my parents, my childhood, schooling, university education, and postdoctoral research, all in Australia. This is followed by a presentation of my life and research in Cambridge, UK and then at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), in Australia, since 1955, where most of my research was done, especially on photosynthesis which included the following areas: Purification of a protochlorophyllide-protein complex; separation of the photochemical systems of photosynthesis; development of photochemical activity in photosynthesis; protein synthesis in plants; comparative photosynthesis of sun and shade plants; role of chlorophyll b in photosynthesis; photochemical properties of C4 plants; molecular interaction of thylakoid membranes; electron transport and ATP formation; and solar energy conversion in photosynthesis. In addition to research on the basics and applications of photosynthesis, I also mention at the end my service as a member of the executive of CSIRO.
