Peter Dennis Mitchell, was a British biochemist who was awarded the 1978 Nobel Prize for Chemistry for his discovery of the chemiosmotic mechanism of ATP synthesis.

Blackman proposed the law of limiting factors in 1905. According to this law, when a process depends on a number of factors, its rate is limited by the pace of slowest factor. Blackman's law of limiting factors determines the rate of photosynthesis.

Daniel Israel Arnon was a Polish-born American plant physiologist, whose research led to greater insights into the operation of photosynthesis in plants.

Melvin Ellis Calvin was an American chemist most famed for discovering the Calvin cycle along with Andrew Benson and James Bassham, for which he was awarded the 1961 Nobel Prize in Chemistry.
