Interessen‐Gemeinschaft Farbenindustrie AG ("Dye industry syndicate, Inc."), commonly known as IG Farben, was a German chemical and pharmaceutical conglomerate. Formed in 1925 from a merger of six chemical companies—BASF, Bayer, Hoechst, Agfa, Chemische Fabrik Griesheim-Elektron, and Chemische Fabrik vorm. Weiler Ter Meer[1]—it was seized by the Allies after World War II and divided back into its constituent companies.[a]

In its heyday, IG Farben was the largest company in Europe and the largest chemical and pharmaceutical company in the world.[4] IG Farben scientists made fundamental contributions to all areas of chemistry and the pharmaceutical industry. Otto Bayer discovered the polyaddition for the synthesis of polyurethane in 1937,[5] and several company scientists became Nobel laureates: Carl Bosch and Friedrich Bergius in 1931 "for their contributions to the invention and development of chemical high pressure methods",[6] Gerhard Domagk in 1939 "for the discovery of the antibacterial effects of prontosil",[7] and Kurt Alder (with Otto Diels) in 1950 "for their discovery and development of the diene synthesis".[8]

The company had ties in the 1920s to the liberal German People's Party and was accused by the Nazis of being an "international capitalist Jewish company".[9] A decade later it was a Nazi Party donor, and became a large government contractor after the Nazi takeover of Germany in 1933, providing significant material for the German war effort. Described as "the most notorious German industrial concern during the Third Reich",[10] IG Farben relied on slave labour from concentration camps, including 30,000 from Auschwitz.[11] One of its subsidiaries supplied the poison gas, Zyklon B, that killed over one million people in gas chambers during the Holocaust.[b][13]

The Allied Control Council seized the company at the end of the war,[a][14] and the US authorities put its directors on trial. Held from 1947 to 1948 as one of the subsequent Nuremberg trials, the IG Farben trial saw 23 IG Farben directors tried for war crimes and 13 convicted.[15] By 1951 all had been released by the American high commissioner for Germany, John J. McCloy.[16][17] What remained of IG Farben in the West (East Germany nationalized the plants on its territory) was split in 1951 into its six constituent companies, then again into three: BASF, Bayer and Hoechst.[a] These companies continued to operate as an informal cartel and played a major role in the West German Wirtschaftswunder. Following several later mergers the main successor companies are Agfa, BASF, Bayer and Sanofi. In 2004 the University of Frankfurt[disambiguation needed], housed in the former IG Farben head office, set up a permanent exhibition inside the building for the slave labourers and those killed by Zyklon B.[18]

Early history[edit]


At the beginning of the 20th century, the German chemical industry dominated the world market for synthetic dyes. Three major firms BASF, 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.[19] 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 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".[20]

Carl Duisberg, chairman of Bayer, argued in 1904 for a merger of Germany's dye and pharmaceutical companies.[21]

With the world market for synthetic dyes and other chemical products dominated by the German industry, German firms competed vigorously for market shares. Although cartels were attempted, they lasted at most for a few years. Others argued for the formation of a profit pool or Interessen-Gemeinschaft (abbr. IG, lit. Community of interest).[22] In contrast, the chairman of Bayer, Carl Duisberg, argued for a merger. During a trip to the United States in the spring of 1903 he had visited several of the large American trusts such as Standard Oil, U.S. Steel, International Paper and Alcoa.[23] 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.[24][page needed]

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 and Agfa 14 percent of all profits.[25] 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.[26]

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.[27] In 1908, Hoechst and Cassella acquired 88 % 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.[27]


Completed in 1930, the IG Farben Building in Frankfurt was seized by the Americans after the war. In 1996 it was transferred to the German government and in 2001 to the University of Frankfurt[disambiguation needed]

IG Farben was founded in December 1925 as a merger of six companies: BASF (27.4 percent of equity capital), Bayer (27.4 percent), Hoechst including Cassella and Chemische Fabrik Kalle (27.4 percent), Agfa (9 percent), Chemische Fabrik Griesheim-Elektron (6.9 percent) and Chemische Fabrik vorm. Weiler Ter Meer (1.9 percent).[1] The supervisory board members became widely known as, and were said to jokingly call themselves, the "Council of Gods" (Rat der Götter);[28] the designation was later used as the title of a 1950 East German movie.

The IG Farben supervisory board, commonly known as the "Council of Gods", in 1926.[c]

In 1926 IG Farben had a market capitalization of 1.4 billion Reichsmark and a workforce of 100,000, of which 2.6 percent were university educated, 18.2 percent were salaried professionals and 79.2 percent were workers.[1] BASF was the nominal survivor; all shares were exchanged for BASF shares. Similar mergers took place in other countries. In the United Kingdom Brunner Mond, Nobel Industries, United Alkali Company and British Dyestuffs merged to form Imperial Chemical Industries in September 1926. In France Établissements Poulenc Frères and Société Chimique des Usines du Rhône merged to form Rhône-Poulenc in 1928.[29] The IG Farben Building, headquarters for the conglomerate in Frankfurt am Main, Germany, was completed in 1931. In 1938 the company had 218,090 employees.[30]

IG Farben was controversial on both the far left and far right, partly for the same reasons, related to the size and international nature of the conglomerate and the Jewish background of several of its key leaders and major shareholders. Far-right newspapers of the 1920s and early 1930s accused it of being an "international capitalist Jewish company". The liberal and business-friendly German People's Party was its most pronounced supporter. Not a single member of the management of IG Farben before 1933 supported the Nazi Party; four members, or a third, of the IG Farben supervisory board were themselves Jewish.[9] The company ended up being the "largest single contribution" to the successful Nazi election campaign of 1933;[31] there is also evidence of "secret contributions" to the party in 1931 and 1932.[32]

Throughout the 1930s the company underwent a process of Ayranization, and by 1938 Jewish employees had been dismissed and the Jews on the board had resigned. The last few left in 1938 after Hermann Göring issued a decree, as part of the Nazis' Four Year Plan (announced in 1936), that the German government would make foreign exchange available to German firms to fund construction or purchases overseas only if certain conditions were met, which included making sure the company employed no Jews.[33]


IG Farben facilities in Germany, 1932

IG Farben's products included synthetic dyes, nitrile rubber, polyurethane, prontosil, and chloroquine. The nerve agent Sarin was first discovered by IG Farben.[34] The company is perhaps best known for its role in producing the poison gas Zyklon B. One product crucial to the operations of the Wehrmacht was synthetic fuel, made from lignite using the coal liquefaction process.

IG Farben scientists made fundamental contributions to all areas of chemistry. Otto Bayer discovered the polyaddition for the synthesis of polyurethane in 1937.[5] Several IG Farben scientists were awarded a Nobel Prize. Carl Bosch and Friedrich Bergius were awarded the Nobel Prize in Chemistry in 1931 "in recognition of their contributions to the invention and development of chemical high pressure methods".[6] Gerhard Domagk was awarded the Nobel Prize in Physiology or Medicine in 1939 "for the discovery of the antibacterial effects of prontosil".[7] Kurt Alder was awarded the Nobel Prize in Chemistry (with Otto Diels) in 1950 "for his [their] discovery and development of the diene synthesis".[8]

World War II and the Holocaust[edit]

Growth and slave labour[edit]

IG Farben has been described as "the most notorious German industrial concern during the Third Reich".[10] The company relied on slave labour from concentration camps, and one of its subsidiaries supplied the poison gas, Zyklon B, that killed over one million people in gas chambers.[35]

When World War II began, IG Farben was the fourth largest corporation in the world and the largest in Europe.[36] In 1942 it opened a Buna-N (synthetic rubber) plant, Monowitz Buna Werke, near the Monowitz concentration camp, part of the Auschwitz concentration camp complex in German-occupied Poland. (Monowitz came to be known as Auschwitz III; Auschwitz I was the administrative centre and Auschwitz II-Birkenau the extermination camp.) The IG Farben plant's workforce consisted of slave labour from Auschwitz, leased to the company by the SS for a low daily rate.[37]

By 1943 IG Farben was manufacturing products worth three billion marks in 334 facilities in occupied Europe; almost half its workforce of 330,000 men and women consisted of slave labour or conscripts, including 30,000 Auschwitz prisoners. Altogether its annual net profit was around RM 0.5 billion.[2] In 1945, according to Raymond G. Stokes, it manufactured all the synthetic rubber and methanol in Germany, 90 percent of its plastic and "organic intermediates", 84 percent of its explosives, 75 percent of its nitrogen and solvents, around 50 percent of its pharmaceuticals, and around 33 percent of its synthetic fuel.[38]

Staff of the Bayer group at IG Farben conducted medical experiments on concentration-camp inmates. In one such experiment, which tested an anaesthetic, Bayer paid RM 150 per person for the use of 150 female inmates of Auschwitz, who died as a result of the research.[39][40]

Zyklon B[edit]

Between 1942 and 1945 an IG Farben cyanide-based pesticide, Zyklon B, was used to kill over one million people, mostly Jews, in gas chambers in Europe, including in the Auschwitz II and Majdanek extermination camps in occupied Poland.[41] The poison gas was supplied by an IG Farben subsidiary, Degesch (Deutsche Gesellschaft für Schädlingsbekämpfung mbH).[35] Degesch originally supplied the gas to Auschwitz to fumigate clothing that was infested with lice, which carried typhus. Fumigation took place within a closed room, but it was a slow process, so Degesch recommended building a small gas chamber, which heated up the gas and made it work faster.[42] The gas was first used on human beings in Auschwitz (650 Soviet POWs and 200 others) in September 1941.[43]

The historian Peter Hayes (Industry and Ideology: I. G. Farben in the Nazi Era, 2001) 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.[44]

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. Bruno Tesch, a chemist who had been involved in the development of Zyklon B, reportedly told a secretary around June 1942 that Wehrmacht officers had talked about gassings (Tesch was hanged by the British in 1946), and the general manager of Degesch is said to have learned about the gassings from Kurt Gerstein of the SS.[45] IG Farben owned 42.5 percent of Degesch shares, and three members of Degesch's 11-person executive board, Wilhelm Rudolf Mann, Heinrich Hörlein and Carl Wurster, were directors of IG Farben.[46] Mann, who had been an SA-Sturmführer,[47] was the chair of Degesch's board. Peter Hayes writes that the board did not meet after 1940, and that although Mann "continued to review the monthly sales figures for Degesch, he could not necessarily have inferred from them the uses to which the Auschwitz camp was putting the product".[12] IG Farben executives did visit Auschwitz but not Auschwitz II-Birkenau, where the gas chambers were located.[45]

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. According to the post-war testimony of Rudolf Höss, the Auschwitz commandant, he was asked by Walther Dürrfeld, technical manager of the IG Farben Auschwitz plant, whether it was true that Jews were being cremated at Auschwitz. Höss replied that he could not discuss it, and thereafter assumed that Dürrfeld knew.[48] Dürrfeld, a friend of Höss, denied knowing about it.[49]

Mann, Hörlein and Wuster were acquitted at the IG Farben trial in 1948 of having supplied Zyklon B for the purpose of mass extermination. The judges ruled that the prosecution had not shown that the defendants or executive board "had any persuasive influence on the management policies of Degesch or any significant knowledge as to the uses to which its production was being put".[46] In 1949 Mann became head of pharmaceutical sales at Bayer.[47] Hörlein became chair of Bayer's supervisory board.[50] Wurster continued as chair of the IG Farben board, helped to reestablish the company BASF, and became an honorary professor at the University of Heidelberg.[51] Dürrfeld was sentenced to eight years, then pardoned in 1951 by John McCloy, the American high commissioner for Germany, after which he joined the management or supervisory boards of several chemical companies.[49]

Break-up and liquidation[edit]

Allied Control Council Law No. 9[edit]

As the Soviet Union approached Auschwitz in January 1945 to liberate it, IG Farben reportedly destroyed the company's records inside the camp.[52] After the war the Allied Control Council seized the company's assets—under Allied Control Council Law No. 9, "Seizure of Property owned by I.G. Farbenindustrie and the Control Thereof", dated 30 November 1945—for "knowingly and prominently ... building up and maintaining German war potential".[14][2] It was decided that the conglomerate would be broken up, certain plants destroyed and others dispersed or appropriated as reparations, and that the Allies would take control of the company's research and production facilities.[14]

IG Farben trial[edit]

The defendants in the dock on the first day of the IG Farben trial, 27 August 1947

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 (Nuremberg) against leading industrialists of Nazi Germany. There were five counts against the IG Farben directors:

  • "the planning, preparation, initiation, and waging of wars of aggression and invasions of other countries;
  • "committing war crimes and crimes against humanity through the plunder and spoliation of public and private property in countries and territories that came under German occupation;
  • "committing war crimes and crimes against humanity through participating in the enslavement and deportation for slave labor of civilians from German-occupied territories and of German nationals;
  • "participation by defendants Christian Schneider, Heinrich Buetefisch, and Erich von der Heyde in the SS, a recently-declared criminal organization; and
  • "participation in a common plan or conspiracy to commit crimes against peace".[53][15]

Of the 24 defendants arraigned, one fell ill and his case was discontinued. The indictment was filed on 3 May 1947; the trial lasted from 27 August 1947 until 30 July 1948. The judges were Curtis Grover Shake (presiding), James Morris, Paul M. Hebert, and Clarence F. Merrell as an alternate judge. Telford Taylor was the chief counsel for the prosecution. Thirteen defendants were found guilty, although all were cleared of the first count of waging war.[53] All defendants who were sentenced to prison received early release. Most were quickly restored to their directorships and other positions in post-war companies, and some were awarded the Federal Cross of Merit.[54] Those who served prison sentences included:

Because of the company's entanglement with the Nazis, the Allies regarded it as too morally corrupt to be allowed to continue to exist. The Soviet Union seized most of IG Farben's assets located in the Soviet occupation zone, as part of their reparation payments. In the western occupation zone, however, the idea of destroying the company was quickly abandoned as the policy of denazification evolved,[10] in part due to the need for productive industry to support reconstruction, and in part because of the company's large entanglement with American companies, notably with the successors of Standard Oil, which IG Farben was modelled after and which had itself been broken up into several companies. In the late 1940s IG Farben was rebuilt in the western zones and continued doing business. In 1951 the company was split into its original constituent companies. The four largest quickly bought the smaller ones.[citation needed]


Agfa, BASF and Bayer remained in business; Hoechst spun off its chemical business in 1999 as Celanese AG before merging with Rhône-Poulenc to form Aventis, which later merged with Sanofi-Synthélabo to form Sanofi. Two years earlier, another part of Hoechst was sold in 1997 to the chemical spin-off of Sandoz, the Muttenz (Switzerland) based Clariant. The successor companies remain some of the world's largest chemical and pharmaceutical companies.[citation needed]

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.[citation needed]


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.[68]

On 10 November 2003 its liquidators filed for insolvency,[69] but this did not affect the existence of the company as a legal entity. While it did not join a national compensation fund set up in 2001 to pay the victims, it contributed 500,000 DM (£160,000 or €255,646) towards a foundation for former captive labourers under the Nazi regime. The remaining property, worth DM 21 million (£6.7 million or €10.7 million), went to a buyer.[70] Each year, the company's annual meeting in Frankfurt was the site of demonstrations by hundreds of protesters.[68] Its stock (denominated in Reichsmarks) traded on German markets until early 2012. As of 2012 it still existed as a corporation in liquidation.[71]

IG Farben in media[edit]




  • In Foyle's War series eight, episode 1 ("High Castle"), Foyle tours Monowitz as part of his investigation of the murder of a London University professor, who as a translator for the Nuremberg Trials becomes involved with an American industrialist who owns a petroleum company, and a German war criminal named Linz, who also turns up dead, in his cell. Linz's firm, IG Farben, had hired from the SS forced laborers incarcerated at Moskowitz.
