Johann Rudolph Geigy (1733-1793) founded J.R. Geigy AG in 1758, selling wares such as dyestuffs, pharmaceutical supplies, spices, and coffee. The company found success in the dyestuffs industry, leading Johann Rudolf Geigy (1830-1917), great-grandson of the company's founder, to establish the company's dyeworks in 1857 for synthetic dye manufacture and research. By 1934, the company expanded to the US, and in 1971, it merged with Ciba AG to form Ciba-Geigy AG. The company exists today as Novartis Pharmaceuticals Company.
