The definition of chirality as property of optically active compounds of molecules was in fact introduced by [[Pasteur]] who however originally used a term ''dissymmetry'' instead. The word ''chirality'' is derived from greek ''chiros'' meaning 'hand'. According to Whyte the term chirality was coined by [[lord Kelvin]] who used it for the first time in the [[physics]] at the turn of the 20th century. Its introduction into [[organic chemistry]] is attributed to Cahn, Ingold and Prelog.<ref>{{cite web |author=Otakar Červinka |title=Chiralita a pojmy s ní související (Chirality and associated terms) |publisher=Chem.
