The company, which created aspirin in 1897, makes health care products (diagnostic equipment and pharmaceuticals), agricultural products (crop protection and animal health), and specialty materials (plastics and synthetic rubber). It operates in the US through Bayer Corporation. Bayer has reorganized, spinning off its divisions and becoming a management holding company. It also has separated its former chemicals subgroup, which was spun off as a publicly traded company called Lanxess in early 2005. In November 2004 Bayer closed a deal for Roche’s consumer health unit for nearly $3 billion.

The company was founded in 1863. It was formerly known as Farbenfabriken Bayer AG and changed its name to Bayer AG in 1972.
