More Than Animal Health

It all started with a friendship between two men, and two kitchen stoves. Businessman Friedrich Bayer and dyer Johann Friedrich Weskott utilized both of these to conduct experiments, discovering how to make the dye fuchsine, a synthetic dyestuff. In 1863, they established a company that marketed and manufactured synthetic dyestuffs to the textile industry, which at the time was growing rapidly in the wake of industrialization. 

Eventually, Bayer developed into a larger company with international operations. Although dye remained the company’s largest division for quite some time, new areas of business, focused on pharmaceuticals, health, technology and agriculture, were added over time.

Today, Bayer is a leading life science company with core competencies in the areas of health care and agriculture. Bayer is contributing to finding solutions to some of the major challenges of our time, including in the animal-health space. Guided by the purpose “Bayer: Science for a better life,” Bayer products and services help prevent, alleviate and treat diseases impacting animals, people and plants.
