Ullmann’s Encyclopedia of Industrial Chemistry is the world’s largest and perhaps most renowned reference work in industrial chemistry. The first edition of the Ullmann’s Encyclopedia of Industrial Chemistry was published in German by Professor Fritz Ullmann in 1914.

The second edition, also published in German by Professor Fritz Ullmann, provides great examples of chemical technology in the 1930s. More examples can be found on the Ullmann’s Encyclopedia homepage.
