Stanley Miller in 1999, posed with an apparatus like that used in the original experiment. At the time of the Miller–Urey experiment, Harold Urey was a Professor of Chemistry at the University of Chicago who had a well-renowned career, including receiving the Nobel Prize in Chemistry in 1934 for his isolation of deuterium [21] and leading ...

Several decades later, the Miller-Urey experiment provided the first empirical basis for these ideas. Inspired by Oparin's theory, University of Chicago chemists Stanley Miller and Harold Urey applied an electric discharge analogous to a lightning strike to a seawater-like system of water and reduced gasses meant to simulate the prebiotic ...
1953 – Stanley L. Miller & Harold C. Urey: Miller–Urey experiment demonstrates that organic compounds can arise spontaneously from inorganic ones. 1955 – Clyde L. Cowan and Frederick Reines confirm the existence of the neutrino in the neutrino experiment. 1958 – Meselson–Stahl experiment proves that DNA replication is semiconservative.
Urey, along with his student Stanley Miller, may be best remembered for the renowned Miller-Urey experiment, which shows that a mixture of ammonia, methane and hydrogen, when exposed to ultraviolet radiation and water, can interact to form amino acids, the "building blocks" of terrestrial life.

The labeled release (LR) experiment (PI: Gilbert Levin, Biospherics Inc.) gave the most promise for exobiologists. In the LR experiment, a sample of Martian soil was inoculated with a drop of very dilute aqueous nutrient solution. The nutrients (7 molecules that were Miller-Urey products) were tagged with radioactive 14 C.
The hypothesis gained some empirical support in 1953 with the classic Miller–Urey experiment. Since then, the primordial soup theory (Oparin–Haldane hypothesis) has become the foundation in the study of abiogenesis. [88] [89] [90]
