Dr. Hans Gaffron was born in Lima, Peru, on May 17, 1902, and was a son of the German physician Eduard Gaffron and his wife Hedwig von Gevekot.[3]
He was one of the earlier researchers trying to elucidate the mechanistic and biochemical details of photosynthesis and plant metabolism.[4] His most notable finding was the discovery of a process whereby unicellular green algae can produce molecular Hydrogen (H2) in the presence of light, and that the precursors were derived from photosynthetic water-splitting.[5] Applications based on his work have led to many efforts to develop H2 as a renewable biofuel.[6]
