It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index. Celltech was instrumental in changing the UK's system of technology transfer from research to business, and in creating the biotechnology industry.<ref name=":0">{{Cite journal |last=Dodgson |first=Mark |author-link=Mark Dodgson |date=June 1990 |title=The Shock of the New: The Formation of Celltech and the British Technology Transfer System |url=http://journals.sagepub.com/doi/10.1177/095042229000400205 |journal=Industry and Higher Education |language=en |volume=4 |issue=2 |pages=97–104 |doi=10.1177/095042229000400205 |issn=0950-4222|url-access=subscription }}</ref>

==History==

Celltech was formed in 1980 in response to the concern that Britain was failing to commercialise its science and was missing out on the potential of the new biotechnology. There was especial concern that whereas US firms had been creating rapidly growing firms such as Genentech around scientific discoveries in biotechnology, the UK had missed opportunities such as that believed to be provided by the Nobel Prize-winning discovery of the production technique for Monoclonal antibody by Cesar Milstein and Georges Kohler at Cambridge University.<ref name=":0" />

The creation of Celltech was complicated, involving the National Enterprise Board, the National Research Development Corporation, and the Medical Research Council. The decision was made to give Celltech exclusive rights to all biotechnology discoveries in UK research institutions and universities. Although the company was conceived under a Labour Government it was born under a Conservative government, with the Minister responsible, Sir Keith Joseph, being particularly averse to government intervention in industry. As a result, he ensured the company was majority owned by the private sector. The company thus began life with very high expectations: first, that a small start up could successfully commercialise the UK's scientific output in biotechnology, and second, that it could meet the profit expectations of private sector investors.<ref>Dodgson, M. (1990) Celltech: The First Ten Years of A Biotechnology Company, Discussion Paper Series, Science Policy Research Unit, University of Sussex, February 1990.</ref>

Celltech's founding CEO was Gerard Fairtlough, who worked in the National Enterprise Board and saw the opportunities presented by biotechnology. He created the plan for Celltech and when the Board was created, it believed he was the best person to lead it. Fairtlough was an inspirational leader with innovative ideas on organisation.<ref>{{Cite book |last=Fairtlough |first=Gerard |author-link=Gerard Fairtlough |title=The Handbook of Industrial Innovation |publisher=Edward Elgar Publishing |year=1994 |isbn=1852786558 |veditors=Dodgson M, Rothwell R |publication-date=1994 |pages=325–6 |chapter=26. Innovation and Organization}}</ref> In the decade that Fairtlough led Celltech, he not only helped found a significant scientific endeavour whose example led to improved ambition and ability to commercialise UK research, but introduced a new way of organising high technology firms.<ref>{{Cite book |last=Dodgson |first=Mark |author-link=Mark Dodgson |title=The Management of Technological Learning |publisher=De Gruyter |year=1991 |series=de Gruyter Studies in Organization |volume=29 |location=Berlin, Boston|pages=25–37|doi=10.1515/9783110867749|isbn=978-3-11-086774-9 }}</ref>
