(March 2009) American IG is the name of a company, and it owes its genesis to a German business conglomerate, namely, Interessens-Gemeinschaft Farbenindustrie AG, or IG Farben for short. The business and the industrial empire, which the “IG” controlled and commanded has been described as “a state within a state”.

The Farben cartel was created in 1925, when Hermann Schmitz, the master organizer, with the Wall Street financial assistance, created the super-giant chemical corporation, combining six already giant German chemical companies — Badische Anilin- und Sodafabrik Ludwigshafen (BASF), Bayer, Agfa, Hoechst, Weiler-ter-Meer, and Griesheim-Elektron. These six companies were merged into Inter-nationale Gesellschaft Farbenindustrie AG or, IG Farben, for short.

In the year 1928, American holdings of IG Farben, namely, the American branches of Bayer Company, General Aniline Works, Agfa Ansco, and Winthrop Chemical Company, were organized into a Swiss holding company, which was christened Internationale Gesellschaft für Chemische Unternehmungen AG or IG Chemie, in short. The controlling interest of this entity rested with IG Farben in Germany. In the following year, in 1929, just a decade before the outbreak of the Second World War, these American firms merged to become American IG Chemical Corporation, or American IG, later renamed General Aniline & Film.

On the eve of World War II, IG Farben, the German chemical conglomerate was the largest manufacturing enterprise in the world and exercised extraordinary economic and political clout in the Nazi Germany. In 1936, they were the principal source for Zyklon B, the poison used in German concentration camps. From 1942-1945, the company used slave labor from Nazi concentration camps. After 1945, three members of the Board of Governors of American IG were tried and convicted as German war criminals. In 1952, the IG Farben was split into BASF, Bayer, and Hoechst again.

General Aniline & Film (or GAF) went on to produce the View-Master, a children's toy, now made today by Mattel's "Fisher-Price" division. GAF today still exists as GAF Materials Corporation, mainly as a manufacturer of asphalt and building materials. See also Interhandel References Wall Street Paves the Way for Hitler I.G.
