Interessen-Gemeinschaft Farbenindustrie x I G Farben

Interessen-Gemeinschaft Farbenindustrie was a German conglomerate of companies formed in 1925 - many produced dyes, but soon later turning to advanced chemistry. IG Farben was founded as a reaction to Germany's defeat in World War One and held a monopoly on chemical production. During the National Socialist regime, it manufactured Zyklon B, a poison used for delousing, and later used as the lethal agent in the gas chambers of the death camps of Auschwitz and Majdanek. The company was a major user of slave labour and as a result 13 directors of IG Farben were sentenced to prison terms between one and eight years before a US military tribunal at the Nuremberg Trials, following the IG Farben Trial (1947-1948). As a result, in 1951, the company was split up into the original constituent companies.
