Sigma-Aldrich Corporation (NASDAQ: SIAL) is a life science and high technology company with over 7,600 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 and Aldrich Chemical Company merged in 1975, producing a current total corporate offering of more than 100,000 chemical products.

The company’s roots spring from 1934 in St. Louis, MO, when two brothers, Aaron Fischer and Bernard Fischlowitz, launched a small consulting firm. The two chemical engineers named their partnership Midwest Consultants – parent company of Sigma Chemical Company – and began to help St. Louis businesses produce a variety of specialty products including cosmetics, shoe dressings, and adhesives and inks for cardboard packaging. The firm incorporated in 1935 and hired Dan Broida, another chemical engineer out of Washington University in St. Louis, to manage the company’s growing consulting and production businesses.
