Eilhard Mitscherlich



  He was a German chemist, who is perhaps best remembered today for his law of isomorphism (1819), which states that substances of analogous composition and structure may substitute similar elements. This relationship was used by Berzelius in early attempts to assign relative masses to the elements which led to a successful creation of the periodic table by Mendeleev and Meyer half a century later.
