The manager of a French sugar beet processing factory discovered the first one in 1833 when he was able to separate it from malt extract.  The second example was discovered three years later, when Ambrose Schwann was able to demonstrate that adding an extract from stomach lining worked much better than hydrochloric acid alone in digesting meat.  The term for these substances was finally coined in 1878 by German physiologist Wilhelm Kuhne whose vitalist predisposition led him to believe that the ability to cause fermentation was a property of living material only.  FTP, diastase and pepsin are examples of this class of substances, which act as catalysts for cellular reactions.
