March 10th is Jeremias Benjamin Richter's birthday. Richter was a German chemist who introduced the term stoichiometry to chemistry. He noticed the ratio of reactants by weight used in a chemical reaction was always the same. This lead to the law of equivalent or multiple proportions. This discovery was one of the first steps towards a new atomic model of chemical reactions.
