In this historical perspective, we focus on selected discoveries that Albert Frenkel (1919-2015) made all by himself - single-handedly - which is the discovery of photophosphorylation and NAD reduction in anoxygenic photosynthetic bacteria. Then, we present various aspects of his research life through his unpublished letters with some key scientists in his research field. To give a glimpse of his personal life, we have also provided some photographs.
