Daniel Israel Arnon (November 14, 1910 – December 20, 1994) was a Polish-born American plant physiologist whose research led to greater insights into the operation of photosynthesis and nutrition in plants. 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. In 1954, Arnon, Mary Belle Allen and F. Robert Whatley discovered photophosphorylation in vitro.
