Ciba-Geigy AG

Ciba-Geigy AG was a Swiss chemical and pharmaceutical group headquartered in Basel, formed in 1970 through the merger of CIBA (Gesellschaft für Chemische Industrie in Basel) and J. R. Geigy. The company operated globally across pharmaceuticals, crop protection, and specialty chemicals, including dyestuffs, pigments, and polymer additives.

In 1996, Ciba-Geigy merged with Sandoz to create Novartis, with most pharmaceutical activities transferred to the new entity. Its specialty chemicals businesses were spun off in 1997 as Ciba Specialty Chemicals (acquired by BASF in 2009), and its crop protection operations later became part of Syngenta in 2000 through the combination of Novartis and AstraZeneca agribusinesses. The Ciba-Geigy name is associated with foundational developments in modern specialty chemicals and life sciences in Switzerland.
