Opel traces its roots to a sewing machine manufacturer founded by Adam Opel in 1862 in Rüsselsheim am Main. The company began manufacturing bicycles in 1886 and produced its first automobile in 1899. After listing on the stock market in 1929, General Motors took a majority stake in Opel and then full control in 1931, establishing an American ownership of the German automaker for nearly 90 years.
