A collection of information and resources about some of the people whose work has helped build biotechnology into one of the most important tools in our lives today.
James Allison (1948)
Born: Alice, Texas, USA. James Allison is best known for helping to elucidate the mechanism behind T cells activation and for pioneering the first immune checkpoint inhibitor drug for treating cancer. His work has radically transformed the landscape for cancer treatment, shifting it away from targeting a tumour to instead using the immune system to destroy cancer cells.
Werner Arber (1929)
Born: Granichen, Switzerland. Werner Arber is a Swiss microbiologist and geneticist who together with Daisy Dussoix helped discover and understand the mechanism of restriction enzymes, laying the foundation for their adoption as molecular scissors. These enzymes today are a fundamental tool for many different types of biotechnology, including DNA sequencing and gene cloning. (Photo credit: Antonio G Colombo).
Brigitte Askonas (1923 - 2013)
Born: Vienna, Austria. Askonas co-developed one of the first systems for the cloning of antibody-forming B cells in vivo, some of the earliest monoclonal antibodies. She was also one of the first scientists to isolate and clone virus specific T lymphocytes, laying the foundation for defining different influenza sub-sets and improving vaccines.

Paul Berg (1926)
Born: Brooklyn, New York, United States. Berg was the first to demonstrate the possibility of making recombinant DNA and helped pioneer guidelines to limit the potential harm posed by genetic engineering. (Photo credit: Albert and Mary Lasker Foundation).
Herbert Boyer (1936)
Born: Derry, Pennsylvania, United States. Together with Stanley Cohen, Boyer demonstrated the possibility of producing recombinant DNA in bacteria in 1973. This they did by combining a gene for frog ribosomal RNA with a bacterial plasmid which was then put into a strain of E-coli for expression. Based on this technique Boyer helped found Genentech, the first biotechnology company dedicated to commercialising recombinant DNA. This he did in 1976 in collaboration with Robert Swanson.

Stanley Cohen (1935)
Born: Perth Amboy, New Jersey, United States. Together with Herbert Boyer, Stanley Norman Cohen demonstrated the possibility of producing recombinant DNA in bacteria in 1973. This they did by combining a gene for frog ribosomal RNA with a bacterial plasmid which was then put into a strain of E-coli for expression. The work laid the foundation for the birth of Genentech, the first company dedicated to the commercialisation of recombinant DNA.

Francis Crick (1916 - 2004)
Born: Weston Favell, United Kingdom. Together with James Watson, Crick co-discovered the double-helix structure of DNA. This was accomplished with the help of earlier research by Rosalind Franklin and Maurice Wilkins. (Photo credit: MRC, Laboratory of Molecular Biology).
Sally Davies (1949)
Born: Birmingham, United Kingdom. Sally Davies was named the sixth most powerful woman in the UK by Woman’s Hour, a BBC radio programme, in 2013. She is the first woman to hold the post of Chief Medical Officer for England. In 2006 she set up the National Institute for Health Research, a body that has revolutionised the approach to clinical and applied research in the UK. She is also at the forefront of spearheading efforts to combat antimicrobial resistance around the world. All this she has achieved in the midst of dealing with a likely variant of dyslexia, being widowed young and becoming a mother in her forties. Much of her career has been shaped by serendipity and her strong desire to make the world a better place.
Margaret Dayhoff (1925 - 1983)
Born: Philadelphia, Pennsylvania, United States. Dayhoff is known as the founder of bioinformatics. This she did by pioneering the application of mathematics and computational techniques to the sequencing of proteins and nucleic acids and establishing the first publicly available database for research in the area. (Photo credit: Ruth E Dayhoff, National Library of Medicine).
Jennifer Doudna (1964)
Born: Washington DC, United States. Doudna first made her name uncovering the basic structure and function of the first ribozyme, a type of catalytic ribonucleic acid (RNA) that helps catalyse chemical reactions. This work helped lay the foundation for her later helping to pioneer CRISPR-Cas 9, a tool that has provided the means to edit genes on an unprecedented scale and at minimal cost. In addition to her scientific contributions to CRISPR, Doudna is known for spearheading the public debate to consider the ethical implications of using CRISPR-Cas9 to edit human embryos.

Carolyn Green (1965 - 2017)
Born: Pittsburgh, PA, USA. Carolyn E Green was a serial entrepreneur in the life sciences community and a leading voice for women in the sector. In her short life she managed to found and head up numerous companies and held many leadership and sales positions in the biopharmaceutical industry. Her crowning achievement was to be hired by Pfizer to head up its new strategic research and development investments initiative. This entailed working with the corporation’s venture fund to establish partnerships with early-stage companies. Green’s enduring patience and strong mentoring skills, together with her passion to develop products to help patients, set her apart from many others in the biotechnology world.
Beverly Griffin (1930 - 2016)
Born: Delhi, Louisiana. Griffin earned two doctorates in chemistry in an era when it was rare for women to pursue a scientific career. She is best known for her pioneering work on the molecular biology of two viruses that cause cancer - the polyomavirus and Epstein Barr Virus (EBV). From the 1980s she was devoted to understanding how in one setting EBV could cause glandular fever, a largely harmless disease, and yet in another Burkitt's Lymphoma, a major killer of children in Central Africa. She also spearheaded efforts to improve the diagnosis and treatment of the cancer and was a tireless campaigner for raising awareness of the plight of children with the disease in Africa.

Her prime focus is to understand the mechanisms and pathways within the immune system responsible for tumour rejection. Since 2005 she has been a principal investigator for several clinical trials launched to improve the efficacy of cancer immunotherapies. Driven by the desperation of her cancer patients, much of Sharma’s high-flying career is down to the strong determination she developed to overcome the poverty and hardships she faced as the child of Indo-Guyanese immigrants who settled in New York when she was 10 years old.
Joseph Sinkovics (1924)
Born: Budapest, Hungary. Sinkovics was one of the first scientists to recognise the possibility of immortalising a specific antibody-producing cell by fusion with a lymphoma cell, the principle that underlines the generation of monoclonal antibodies today. He has also been a major pioneer in cancer research, being one of the first to discover large granular lymphocytes could kill cancer cells without pre-immunisation of the host and that attenuated (weakened) viruses could destroy tumour cells in vitro which led to his development of some of the first viral therapies against cancer.
