Background
Arnon was born on November 14, 1910, in Warsaw. His father had lost the family"s food wholesale business after World War I and Arnon"s readings of the works of Jack London led him to save up his money to head to California.

University of California, Berkeley.
In 1973, he was awarded the National Medal of Science for "his fundamental research into the mechanism of green plant utilization of light to produce chemical energy and oxygen and for contributions to our understanding of plant nutrition."
Summers spent on the family"s farm helped foster Arnon"s interest in agriculture. He enrolled in the University of California, Berkeley from Poland, and would spend his entire professional career at the school, until his retirement in 1978. He ultimately earned his Doctor of Philosophy in plant physiology at University of California Berkeley under Dennis R. Hoagland and some of his earliest research focused on growing plants in nutrient-enriched water rather than in the soil.
During World World War II, Arnon served in the United States Army in the Pacific Theater of Operations, where he used his prior experience with plant nutrition on Ponape Island, where there was no arable land available and he was able to grow food to feed the troops stationed there using gravel and nutrient-enriched water.
After returning from military service, Arnon performed research on chloroplasts and their role in the photosynthesis process. His work was able to demonstrate how energy from sunlight is used to form adenosine triphosphate, the energy transport messenger within living cells, by adding a third phosphorus group to adenosine diphosphate.
In 1954, Arnon reproduced the process in a laboratory, making him the first to successfully demonstrate the chemical function of photosynthesis, producing sugar and starch from inputs of carbon dioxide and water. A resident of Kensington, California, Arnon died at age 84 on December 20, 1994, in Berkeley, California, of complications resulting from cardiac arrest.
