Daniel Israel Arnon (November 14, 1910 – December 20, 1994)[1] was a Polish-born American plant physiologist and National Medal of Science recipient whose research led to greater insights into the operation of photosynthesis and nutrition in plants.[2]

In the first part of his professional career, the so-called "Plant Nutrition Years (1936-1950)", Arnon and collaborators discovered the essentiality of molybdenum for the growth of all plants and of vanadium for the growth of green algae. In the second one, the so-called "Photosynthesis Period (1951-1978)", plant micronutrient work led him to photosynthesis.[2]

In 1954, Arnon, Mary Belle Allen and Frederick Robert Whatley discovered photophosphorylation in vitro.[2] In 1967, for this work, he was nominated jointly with Allen and Whatley for a Nobel Prize in Chemistry.[3]
