Sigma Aldrich



Sigma Aldrich:


Sigma-Aldrich Corporation is an American life science and high technology company with over 9,600 employees and operations in 40 countries .Its chemical and biochemical products and kits are used in scientific research, biotechnology, pharmaceutical development, the diagnosis of disease, and as key components in high technology manufacturing.

Sigma Chemical Company of St Louis and Aldrich Chemical Company of Milwaukee (founded by Alfred Bader) were two leading American specialty chemical companies (companies from which chemists could buy thousands of specific compounds by mail order) when they merged in 1975. By 2001, Sigma-Aldrich had a total corporate offering of more than 100,000 chemical products.


After the merger

Aldrich Chemical Co. merged with Sigma International, Ltd. to form Sigma-Aldrich Corporation in August 1975, when changing trends in chemical research confirmed the synergy to be realized from their complementary product offerings. Annual double-digit growth was the norm in the 80s and 90s, with significant expansion in facilities, major acquisitions and ventures into new market sectors. In December 2000 Sigma-Aldrich launched a strategic plan focusing the Company on “Leadership in Life Science and High Technology.” Other key initiatives on service and process improvements and a strong Internet presence have strengthened Sigma-Aldrich’s current position as a leading technology company. In October, 2000, Sigma-Aldrich announced the intention to enter into a manufacturing and exclusive distribution agreement with Proteome Systems. In Sep, 2001, Sigma-Aldrich donated $250,000—shared equally by the New York Firefighters 9-11 Disaster Relief Fund and the WTC Police Disaster Relief Fund—on behalf of its employees, customers and shareholders.
