Fisons was a British multinational pharmaceutical, scientific instruments and horticultural chemicals company, headquartered in Ipswich with pharmaceutical research and development in Loughborough.
The business was established by Edward Packard in 1843. In 1863 he was joined by his son, also named Edward, who was instrumental in developing the company and rationalising the UK’s fertiliser industry. The company was incorporated in 1895 under the name of Edward Packard & Co. Ltd.
In 1919 the company purchased the fertiliser business of James Fison of Thetford and in 1929 the company’s name was changed to Packard & Fison (Thetford) Limited to reflect the acquisition. In 1942 the company shortened its name to Fisons Ltd.
During the 1950s Fisons promoted the spraying of crops utilising helicopters. In the early 1980s the company decided to focus on pharmaceutical products and its fertiliser activities were sold to Norsk Hydro in 1982.
In late 1995 Fisons was acquired by the United States based Rhone-Poulenc Rorer Inc., which in turn was wholly owned by France’s chemical giant Rhone-Poulenc S. A.
