Stanley Lloyd Miller (March 7, 1930 – May 20, 2007) was a Jewish-American chemist who made landmark experiments in the origin of life by demonstrating that a wide range of vital organic compounds can be synthesized by fairly simple chemical processes from inorganic substances. His research publication in 1953 catapulted him to instant fame, and has been popularised as the Urey-Miller experiment or, more appropriately, the Miller experiment. Over five decades of his continued and dedicated research into chemical evolution of the early Earth had strongly established natural synthesis of chemical building blocks of life from inanimate inorganic molecules, under variable atmospheric conditions. He is aptly regarded as the "father of prebiotic chemistry".
