Geigy was a Swiss chemical company founded in 1758, known for its production of dyes, chemicals, and pharmaceuticals. It played a significant role in the development of synthetic dyes and later expanded into agrochemicals and pharmaceuticals, contributing to advancements in various industries. In 1970, Geigy merged with another company, Ciba, to form Ciba-Geigy, which became a major player in the global chemical and pharmaceutical markets. The company eventually focused on pharmaceuticals and agrochemicals, leading to its later merger with Novartis in 1996, which remains a leading global healthcare company today.
