Founded in 1978 by a small group of visionary scientists, Biogen helped pioneer the biotechnology industry. Today, we are one of the oldest independent biotechnology companies in the world.

For close to four decades, hundreds of thousands of people around the world living with serious illnesses have benefited from innovative and important medicines developed by the people of Biogen. We are proud of the role we have played in advancing the field of biotechnology and helping patients — and are building on this legacy of great science and discovery as we pursue increasingly complex challenges.
