Kemball Bishop

Kemball Bishop was a prominent British chemical manufacturing company founded in 1870, specializing in the production of citric and tartaric acids via fermentation. The company gained significant historical importance in the mid-20th century for its expertise in large-scale fermentation, which led to a pivotal partnership with Pfizer. In the 1940s, it became a key site for the early industrial production of penicillin in the United Kingdom, helping to pioneer the mass manufacture of antibiotics. Pfizer eventually acquired the company in 1958, using its London facilities as the foundation for its first major manufacturing presence outside the United States. The company is recognized as a cornerstone in the transition from industrial chemistry to modern pharmaceutical biotechnology.
