The story

Founded by Adolf von Brüning, Eugen Lucius and Wilhelm Meister on Jan 2, 1863, in Höchst.1

History

The company was founded in 1863 as "Teerfarbenfabrik Meister, Lucius & Co." in Höchst, near Frankfurt and changed its name some years later to "Teerfarbenfabrik Meister Lucius & Brüning". In 1880, it became a stock company "Farbwerke vorm. Meister Lucius & Brüning AG". For the international market the name was simplified to "Farbwerke Hoechst AG". Until 1925, the Hoechst AG was independent. In 1916, the Hoechst AG was one of the co-founders of IG Farben, an advocacy group of Germany's chemicals industry to gain industrial power during and after World War I. In 1925, IG Farben turned from an advocacy group into the well-known conglomerate.

Postwar timeline

Hoechst AG was re-founded on December 7,1951 in Frankfurt when IG Farben was split into its founder companies. The original capitalization of the company was 100,000 Deutsche Mark. By 1953, Hoechst had acquired parts of Knapsack-Griesheim, Kalle AG, Behring Werke, Wacker Chemie and Ruhr Chemie, among others.

In 1957, the company signed a technical cooperation contract with Handok Pharmaceuticals In South Korea

In 1964, the company established a joint venture partnership with Handok Pharmaceuticals in South Korea.

In 1969, Hoechst acquired Cassella. A year later, Hoechst AG took over Berger, Jenson and Nicholson Ltd.

In 1974, Hoechst acquired Foster Grant. Later, in 1986, Hoechst sold Foster Grant to Andlinger & Co.

In 1987, Hoechst acquired the American chemical company Celanese and formed a new Hoechst subsidiary in the US, Hoechst Celanese. A year later, Hoechst AG sold Berger, Jenson and Nicholson Ltd to Williams Holdings.

In 1995, Hoechst merged with Marion Merrell Dow of Kansas City, Missouri forming U.S. subsidiary Hoechst Marion Roussel (HMR).

In 1997, Hoechst underwent a realignment wherein its various businesses were transferred to independent companies, including Nutrinova and Clariant.

Aventis was formed in 1999 after Hoechst AG merged with Rhône-Poulenc S.A. The merged company was headquartered in Strasbourg, Eastern France. As part of the merger, the company demerged many of its industrial businesses into Celanese, which became an independent company again (e.g. the engineering polymers business Ticona).In the same year, Hoechst and Rhône-Poulenc settled Federal Trade Commission charges stating that the merger would violate U.S. antitrust laws.

In 2005, the company became a wholly owned subsidiary of Sanofi-Aventis (now called Sanofi).
