  • "Louis Pasteur could rightly be described as the first stereochemist, having observed in 1842 that salts of tartaric acid collected from wine production vessels could rotate plane polarized light, but that salts from other sources did not. This property, the only physical property in which the two types of tartrate salts differed, is due to optical isomerism."
