The Wahl-Henius Institute of Fermentology, 1135-1147 Fullerton Avenue, was started in October, 1886, by Robert Wahl, Ph.D., and Max Henius, Ph.D. In 1891 the first class in theoretical and practical brewing was started. More than 1200 pupils have graduated from the institute and are now in important positions in all parts of the world where brewing is regarded as a science.

The Institute has published a manual for brewers, American Handbook of Brewing, Malting, and Auxiliary Trades.
