Early history


Background

At the beginning of the 20th century, the German chemical industry dominated the world market for synthetic dyes. Three major firms

, Bayer and Hoechst, produced several hundred different dyes. Five smaller firms, Agfa, Cassella, Chemische Fabrik Kalle, Chemische Fabrik Griesheim-Elektron and Chemische Fabrik vorm. Weiler-ter Meer, concentrated on high-quality specialty dyes. In 1913 these eight firms produced almost 90 percent of the world supply of dyestuffs and sold about 80 percent of their production abroad. The three major firms had also integrated upstream into the production of essential raw materials, and they began to expand into other areas of chemistry such as pharmaceuticals, photographic film,
agricultural chemicals An agrochemical or agrichemical, a contraction of ''agricultural chemical'', is a chemical product used in industrial agriculture. Agrichemical refers to biocides (pesticides including insecticides, herbicides, fungicides and nematicides) and sy ...
and electrochemicals. Contrary to other industries, the founders and their families had little influence on the top-level decision-making of the leading German chemical firms, which was in the hands of professional salaried managers. Because of this unique situation, the economic historian Alfred Chandler called the German dye companies "the world's first truly managerial industrial enterprises". With the world market for synthetic dyes and other chemical products dominated by the German industry, German firms competed vigorously for market shares. Although

and Alcoa. In 1904, after returning to Germany, he proposed a nationwide merger of the producers of dye and pharmaceuticals in a memorandum to Gustav von Brüning, the senior manager at Hoechst. Hoechst and several pharmaceutical firms refused to join. Instead, Hoechst and Cassella made an alliance based on mutual equity stakes in 1904. This prompted Duisberg and Heinrich von Brunck, chairman of BASF, to accelerate their negotiations. In October 1904 an ''Interessen-Gemeinschaft'' between Bayer, BASF and Agfa was formed, also known as the ''Dreibund'' or little IG. Profits of the three firms were pooled, with BASF and Bayer getting 43 percent each and Agfa 14 percent of all profits. The two alliances were loosely connected with each other through an agreement between BASF and Hoechst to jointly exploit the patent on the Heumann-Pfleger indigo synthesis. Within the ''Dreibund'', Bayer and BASF concentrated on dye, while Agfa increasingly concentrated on photographic film. Although there was some cooperation between the technical staff in production and accounting, there was little cooperation between the firms in other areas. Neither were production or distribution facilities consolidated nor did the commercial staff cooperate. In 1908 Hoechst and Cassella acquired 88 percent of the shares of Chemische Fabrik Kalle. As Hoechst, Cassella and Kalle were connected by mutual equity shares and were located close to each other in the Frankfurt area, this allowed them to cooperate more successfully than the ''Dreibund'', although they also did not rationalize or consolidate their production facilities.


Foundation

IG Farben was founded in December 1925 as a merger of six companies:

Weiler Ter Meer (1.9 percent). The supervisory board members became widely known as, and were said to call themselves jokingly, the "Council of Gods" (''Rat der Götter''). The designation was used as the title of an

According to the historian Peter Hayes, "the killings were an open secret within Farben, and people worked at not reflecting upon what they knew." In 1978 Joseph Borkin, who investigated the company as a United States Justice Department lawyer, quoted an American report: "Without I.G.'s immense productive facilities, its far-reaching research, varied technical expertise and overall concentration of economic power, Germany would not have been in a position to start its aggressive war in September 1939." The company placed its resources, technical capabilities and overseas contacts at the German government's disposal.

The idea was that the inmates would be shaved and showered while their clothes were being fumigated. The gas was first used on human beings in Auschwitz (650 Soviet POWs and 200 others) in September 1941. Peter Hayes compiled the following table showing the increase in Zyklon B ordered by Auschwitz (figures with an asterisk are incomplete). One ton of Zyklon B was enough to kill around 312,500 people. Several IG Farben executives said after the war that they did not know about the gassings, despite the increase in sales of Zyklon B to Auschwitz.

Höss replied that he could not discuss it and thereafter assumed that Dürrfeld knew. Dürrfeld, a friend of Höss, denied knowing about it. Hayes writes that the inmates of Auschwitz III, which supplied the slave labour for IG Farben, were well aware of the gas chambers, in part because of the stench from the Auschwitz II crematoria, and in part because IG Farben supervisors in the camp spoke about the gassings, including using the threat of them to make the inmates work harder.

Seizure by the Allies

The company destroyed most of its records as it became clear that Germany was losing the war. In September 1944 Fritz ter Meer, a member of IG Farben's supervisory board and future chair of Bayer's board of directors, and Ernst Struss, secretary of the company's managing board, are said to have made plans to destroy company files in Frankfurt in the event of an American invasion.

approached Auschwitz in January 1945 to liberate it, IG Farben reportedly destroyed the company's records inside the camp, and in the spring of 1945, the company burned and shredded 15 tons of paperwork in Frankfurt. The Americans seized the company's property under "General Order No. 2 pursuant to Military Government Law No. 52", 2 July 1945, which allowed the US to disperse "ownership and control of such of the plants and equipment seized under this order as have not been transferred or destroyed". The French followed suit in the areas they controlled. On 30 November 1945 Allied Control Council Law No. 9, "Seizure of Property owned by I.G. Farbenindustrie and the Control Thereof", formalized the seizure for "knowingly and prominently ... building up and maintaining German war potential". The division of property followed the division of Germany into four zones: American,

In the Western occupation zone, the idea of destroying the company was abandoned as the policy of denazification evolved, in part because of a need for industry to support reconstruction, and in part because of the company's entanglement with American companies, notably the successors of Standard Oil.

In 1947 the American government put IG Farben's directors on trial. ''The United States of America vs. Carl Krauch, et al.'' (1947–1948), also known as the IG Farben trial, was the sixth of 12 trials for war crimes the U.S. authorities held in their occupation zone in Germany (

The successor companies remain some of the world's largest chemical and pharmaceutical companies. Although IG Farben was officially put into liquidation in 1952, this did not end the company's legal existence. The purpose of a corporation's continuing existence, being "in liquidation", is to ensure an orderly wind-down of its affairs. As almost all its assets and all its activities had been transferred to the original constituent companies, IG Farben was from 1952 largely a shell company with no real activity. In 2001 IG Farben announced that it would formally wind up its affairs in 2003. It had been continually criticized over the years for failing to pay compensation to the former labourers; its stated reason for its continued existence after 1952 was to administer its claims and pay its debts. The company, in turn, blamed ongoing legal disputes with the former captive labourers for its inability to be legally dissolved and have the remaining assets distributed as reparations."IG Farben to be dissolved"
