Sidney W. Fox

Sidney Walter Fox was a Los Angeles-born biochemist responsible for discoveries on the origins of biological systems. Fox explored the synthesis of amino acids from inorganic molecules, the synthesis of proteinous amino acids and amino acid polymers called "proteinoids" from inorganic molecules and thermal energy, and created what he thought was the world's first protocell out of proteinoids and water. He called these globules "microspheres". Fox believed in the process of abiogenesis where life spontaneously organized itself from the colloquially known "primordial soup;" poolings of various simple organic molecules that existed during the time before life on Earth. He also suggested that his experiments possessed conditions that were similar to those of primordial Earth.
