Founding Story

Biogen began in 1978 as Biotechnology Geneva, set up in Switzerland by five academic molecular biologists: Walter Gilbert (Harvard), Phillip Sharp (MIT), Kenneth Murray (Edinburgh), Heinz Schaller (Heidelberg) and Charles Weissmann (Zurich). Weissmann's Zurich laboratory cloned human alpha interferon in 1980, and Murray and Schaller worked on producing hepatitis B antigens with recombinant DNA, work behind later hepatitis B vaccines. Gilbert, who won the 1980 Nobel Prize in Chemistry, left Harvard to run the company. Licensing those discoveries to larger drugmakers, rather than selling its own drugs, is what kept Biogen going through the 1980s.

Kenneth Murray

Co-founder 1978

Background

Sir Kenneth Murray (1930-2013) was a professor of molecular biology at the University of Edinburgh and one of the early developers of recombinant DNA methods in Britain.

Role at Biogen Inc.

Murray co-founded Biogen in 1978. In Edinburgh he and his colleagues used genetic engineering to produce hepatitis B virus antigens in bacteria, work that led to one of the first recombinant vaccines and to diagnostic tests. Royalties from the hepatitis B technology helped sustain Biogen through the 1980s, and Murray used his own share to set up the Darwin Trust of Edinburgh, which funds young scientists. He was knighted in 1993 and died in April 2013.

Education: University of Birmingham. (Exact birth year remains publicly undisclosed).

Phillip Sharp

Co-founder 1978

Background

Phillip A. Sharp is an MIT molecular biologist who shared the 1993 Nobel Prize in Physiology or Medicine for the discovery of split genes, the finding that led to the understanding of RNA splicing.

Role at Biogen Inc.

Sharp was one of Biogen's 1978 founders and served on the company's board for many years. His work on how genes are split and spliced underpins much of later RNA-based drug development, a field in which Biogen became a leader through its antisense alliance with Ionis. In 2002 Sharp also co-founded Alnylam Pharmaceuticals, a developer of RNA interference medicines.

Phillip Sharp was born in 1944 in Falmouth. Education: University of Illinois Urbana-Champaign; Union Commonwealth University.

Walter Gilbert

Co-founder 1978

Background

Walter Gilbert is a Harvard biochemist who shared the 1980 Nobel Prize in Chemistry for developing a method to determine the sequence of DNA.

Role at Biogen Inc.

Gilbert helped found Biogen in 1978 and left his Harvard post to serve as its chief executive from 1981 to 1984, an unusual move for a Nobel laureate at the time. As research spending and losses mounted, the board asked him to step aside and he returned to academic work. He later became an early advocate of the Human Genome Project and in 1992 co-founded Myriad Genetics.

Walter Gilbert was born in 1932 in Boston. Education: Trinity College; University of Cambridge.

Charles Weissmann

Co-founder 1978

Background

Charles Weissmann, born in Budapest in 1931, is a molecular biologist who spent most of his career at the University of Zurich.

Role at Biogen Inc.

Weissmann co-founded Biogen in 1978. In 1980 his Zurich laboratory reported cloning human leukocyte (alpha) interferon and producing it in bacteria, Biogen's first major scientific result. The technology was licensed to Schering-Plough and became Intron A, an early source of royalties. Weissmann later became a leading prion researcher, showing that mice lacking the prion protein gene are resistant to scrapie.

Weissmann was born on October 14, 1931 and died on December 11, 2025. A Hungarian-Swiss molecular biologist, he is known for the first cloning and expression of interferon and for work on the molecular genetics of prion diseases. (Exact birth year remains publicly undisclosed).

Heinz Schaller

Co-founder 1978

Background

Heinz Schaller (1932-2010) was a German molecular biologist and virologist who was a professor at the University of Heidelberg.

Role at Biogen Inc.

Schaller co-founded Biogen in 1978 with Gilbert, Sharp, Murray and Weissmann. At Heidelberg he turned to hepatitis B virus research in the late 1970s, sequenced the viral genome with Gilbert and Murray and contributed to the recombinant DNA work behind a widely used hepatitis B vaccine. He co-founded Heidelberg's Center for Molecular Biology (ZMBH) in 1982, received the Robert Koch Medal in 2004, and with his wife Chica Schaller set up a foundation that funds young biomedical researchers. (Exact birth year remains publicly undisclosed).

Christopher A. Viehbacher

President and Chief Executive Officer

2022 – Present

Christopher Viehbacher became Biogen's CEO on November 14, 2022, after the commercial failure of Aduhelm. He had been CEO of Sanofi from 2008 to 2014, where he bought Genzyme, and before that spent about two decades at GlaxoSmithKline; he later co-founded the investment firm Gurnet Point Capital. At Biogen he launched the Fit for Growth cost program in 2023, discontinued Aduhelm in 2024 and used acquisitions to diversify the company: Reata for $7.3 billion in 2023, HI-Bio for $1.15 billion upfront in 2024 and Apellis for about $5.6 billion in 2026. In Q2 2026 the growth portfolio he built out produced more revenue than the legacy MS drugs, and Biogen's market value was about $33 billion at the end of September 2026.

Michel Vounatsos

Chief Executive Officer

2017 – 2022

Michel Vounatsos, a former Merck executive, was CEO from January 2017 to November 2022. He oversaw the growth of Spinraza after its late-2016 approval and the 2019 Nightstar acquisition, and led the Aduhelm filing, its controversial June 2021 accelerated approval and the weak launch that followed once Medicare restricted coverage in 2022. Biogen announced in May 2022 that he would step down once a successor was found.

George Scangos

Chief Executive Officer

2010 – 2016

George Scangos, previously CEO of Exelixis, ran Biogen Idec from 2010 to 2016. His tenure covered the 2013 launch of Tecfidera, the 2013 purchase of full Tysabri rights from Elan for $3.25 billion, the 2015 return to the Biogen name and the plan to spin off the hemophilia business as Bioverativ. Revenue grew from $4.72 billion in 2010 to $11.45 billion in 2016.

James C. Mullen

Chief Executive Officer

2000 – 2010

James Mullen became Biogen's CEO in 2000 and led the 2003 merger with IDEC Pharmaceuticals that created Biogen Idec. He then ran the combined company through Tysabri's 2004 approval, its withdrawal in 2005 after cases of the brain infection PML and its return to market in 2006, before retiring in 2010.

James L. Vincent

Chief Executive Officer

1985 – 2000

James Vincent joined from Allied Corporation in 1985, when Biogen had accumulated about $100 million of losses, and restructured it around licensing royalties from interferon and hepatitis B technology. That income funded Avonex, approved for multiple sclerosis in 1996, which turned Biogen into a profitable product company. He handed the CEO role to James Mullen in 2000, remained chairman until 2002 and died in 2013.

Walter Gilbert

Chief Executive Officer

1981 – 1984

Nobel laureate Walter Gilbert left Harvard to run Biogen during its start-up years, building research operations in Geneva and Cambridge. The board asked him to step down as losses grew without a marketed product.
