Stanley Miller

Stanley Lloyd Miller (March 7, 1930 – May 20, 2007) was an American chemist who made important experiments concerning 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. In 1952 he performed the Miller–Urey experiment, which showed that complex organic molecules could be synthesised from inorganic precursors. The experiment was widely reported, and provided evidence for the idea that the chemical evolution of the early Earth had caused the natural synthesis of organic compounds from inanimate inorganic molecules.
