Sidney Walter Fox

Sidney Walter Fox was an American biochemist known for his research on the origins of life. He studied how simple organic molecules could have spontaneously formed complex structures like early cell-like systems on primitive Earth. Fox created experiments showing that amino acids and other organic compounds can self-assemble into tiny, membrane-bound clusters called protocells, which resemble primitive life forms. His work helped scientists understand how life might have begun from non-living chemicals through natural processes, offering insights into the origin of life on Earth.
