American Cyanamid

American Cyanamid Company was a leading American conglomerate which became one of the nation's top 100 manufacturing companies during the 1970s and 1980s, according to the Fortune 500 listings at the time. Founded by Frank Washburn in 1907, the company grew to over 100,000 employees worldwide, and had over 200,000 shareholders by the mid-1970s. Its stock was traded on the New York Stock Exchange under the symbol ACY. It was repeatedly reorganized after the mid-1990s, merged with other firms, and saw brands and divisions sold or spun off. The bulk of the former company is now part of Pfizer, with smaller portions belonging to BASF, Procter & Gamble and other firms.
