title: The legacy of Hans Molisch (1856-1937), photosynthesis savant.
abstract: Hans Molisch (1856-1937) was an exceptionally gifted and productive researcher who had broad interests in plant biology, physiology and biochemistry. In addition, he pioneered in isolating a number of species of purple photosynthetic bacteria in pure culture (including Rhodobacter capsulatus), which facilitated his discovery of basic aspects of bacterial photosynthesis. Molisch demonstrated conclusively that molecular oxygen is not produced by photosynthetic bacteria, and discovered the photoheterotrophic growth mode. The range of Molisch's research accomplishments was impressive, and he emerges as a major figure in the history of photosynthesis research. This essay reviews the numerous research contributions made by Molisch, particularly in regard to advancing knowledge of the several forms of photosynthetic metabolism. An English translation of his 1914 paper on the photosynthetic creation of visual images on leaves is included as an Appendix.
