The role of women in biotechnology
Often hidden from view, women have played a major role in the development of biotechnology and medicine. Indeed, women have been at the cutting edge of biotechnology, including Rosalind Franklin who played a fundamental role in deciphering the structure of DNA; Esther Lederberg who discovered the lambda phage which is now a major tool for studying gene regulation and genetic recombination; Margaret Dayhoff who developed the field of bioinformatics; Janet Mertz who created the first piece of recombinant DNA; and Jennifer Doudna and Emmanuelle Charpentier who helped pioneer CRISPR, a revolutionary technique for genome editing.
Here we provide a number of profiles of women who have been key pioneers in biotechnology. These profiles have been compiled as part of an ongoing project to highlight the many contributions women have made to biotechnology. This is a work in progress and we welcome suggestions for other women to be included.
Some of the leading women in biotechnology
Don't hesitate to contact us if you think of other women who have played an important role in the development of biotechnology and who are not here.
June Almeida (1930 - 2007)
Born: Glasgow. Almeida has recently attracted a great deal of media attention in the midst of the COVID-19 crisis as the person responsible for the first visualisation of a human coronavirus. Yet, this barely scratches the surface of her achievements. Leaving school at the age of 16, Almeida managed to forge a major career based on her outstanding skills in electron microscopy. This she did in the midst of bearing a daughter and raising her as a single parent following divorce. Almeida's pioneering advances in immune electron microscopy put her at the forefront of many key breakthroughs in virology in the 1960s and 1970s.
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.

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.
Rosalind Franklin (1920 - 1958)
Born: London, United Kingdom. Rosalind Franklin was an x-ray crystallographer whose work helped uncover the double-helix structure of DNA. (Photo credit: Vittorio Luzzati).
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.

Esther Lederberg (1922 - 2006)
Born: Bronx, New York, United States. Esther Lederberg was a major pioneer of bacterial genetics. She discovered the lambda phage, a bacterial virus which is widely used as a tool to study gene regulation and genetic recombination. She also invented the replica plating technique, which is used to isolate and analyse bacterial mutants and track antibiotic resistance. (Photo credit: The Esther Lederberg Memorial Trust).
Rita Levi-Montalcini (1909 - 2012)
Born: Turin, Italy. An Italian scientist, Rita Levi-Montalcini helped discover the chemical tools the body uses to direct cell growth and build nerves. This knowledge underpins current investigation into how these processes go wrong in diseases like dementia and cancer. (Photo credit: Bernard Becker Medical Library).
Janet Mertz (1949)
Born: The Bronx, New York, USA. Mertz was pivotal to the discovery of the first enzyme for easily joining together DNA from different species and designing the protocol that underpinned the development of the first recombinant DNA cloned in bacteria. Her work not only helped lay the foundation for the development of genetic engineering, but also spurred on the establishment of the first safety guidelines for laboratories involved in genetic manipulation. She has also made key contributions to our understanding about how the human tumour viruses SV40, hepatitis B virus, and Epstein-Barr virus regulate expression of their genes and identified roles oestrogen-related receptors play in breast cancer and responses to therapies. (Photo credit: Janet Mertz).
Christiane Nusslein-Volhard (1942)
Born: Magdeburg, Germany. Christiane Nüsslein-Volhard won the Nobel Prize in 1995, the sixth woman to do so. She was awarded the Prize on the basis of her groundbreaking research that showed how genes regulate the early development of fruit fly embryos. Her discoveries helped create the new discipline of developmental genetics and laid the foundation for understanding genetic defects in human embryos.
Padmanee Sharma (1970)
Born: Georgetown, Guyana. Padmanee Sharma is a leading figure in oncology, specialising in renal, bladder and prostate cancer. 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.
Rosemary Versteegen (1948)
Born: Glasgow, Scotland. Rosemary J Versteegen worked for over twenty years with Life Technologies Inc, which in the 1990s was one of largest suppliers of culture cell products and other scientific reagents to the biotechnology industry. She was pivotal to the company’s success in winning FDA approval for the first diagnostic test using synthetic nucleic acid probes for detecting infection with the human papillomavirus, one of the most common causes of cervical cancer. In addition, Versteegen is one of the co-founders and the Chief Executive Officer of the International Serum Industry Association, an organisation that works to promote standards of excellence and ethics in the animal serum and animal derived products industry.
Francoise Barre-Sinoussi (1947)
Born: Paris, France. Barre-Sinoussi shared the 2008 Nobel Prize in Physiology or Medicine for helping to identify the human immunodeficiency virus (HIV) as the cause of AIDS in 1983. Over the years she has made substantial contributions to understanding the role of innate immune defences in the host in controlling HIV/AIDS and how HIV is transmitted between the mother and child. She has also studied the characteristics that allow some HIV-positive individuals gain resistance to HIV without antiretrioviral drugs. (Photo credit: Karolinska Institute, Press conference, 2008).
Elizabeth Blackburn (1948)
Born: Hobart, Tasmania, Australia. Blackburn is a molecular biologist who was awarded the Nobel Prize in Physiology or Medicine in 2009. She is best known for having discovered a particular repetative sequence of DNA on the telomere, a particular region found at the end of a chromosome that prevents the chromosome ends from fraying and sticking to each other. She also helped identify telomerase, an enzyme that helps replenish telomeres which get shorter every time a cell divides. Such shortening is associated with aging and cancer. (Photo credit: Chemical Heritage Foundation).
Gertrude Elion (1918 - 1999)
Born: New York City, United States. Elion shared the 1988 Nobel Prize in Physiology or Medicine for her contributions to the development of a multitude of new drugs. This included drugs for herpes, leukemia, malaria, gout, immune disorders, and AIDS, and immune suppressants to overcome rejection of donated organs in transplant surgery. Her work earned 45 patents. (Photo credit: Wellcome Images).
Carol Greider (1961)
Born: San Diego, California, United States. Greider shared the Nobel Prize for Physiology or Medicine in 2009 for helping to elucidate the structure of telomeres, a particular region found at the end of a chromosome that prevents the chromosome ends from fraying and sticking to each other, and to identify telomerase, an enzyme that helps replenish telomeres which get shorter every time a cell divides. Such shortening is associated with aging and cancer. She also collaborated in the development of the first telomerase knockout mouse which helped demonstrate how premature aging is linked to increasingly short telomeres. (Photo credit: Keith Weller).
Ingeborg Hochmair-Desoyer (1953)
Born: Vienna, Austria. Hochmair-Desoyer is an electrical engineer who helped create the world's first micro-electric multi-channel cochlear implant. Developed in 1977 the implant enables the user to not only hear sounds but also to understand speech. Since 2000 she has co-founded a number of medical device companies working to help with hearing loss. In 2013 she was awarded the Lasker-DeBakey Clinical Medical Research Award. (Photo credit: Ingeborg J Hochmair-Desoyer).
Dorothy Hodgkin (1910 - 1994)
Born: Cairo, Egypt. Dorothy Hodgkin, was a British biochemist who developed protein crystallography and X-ray crystallography which was used to confirm the structure of penicillin, for which she won the Nobel Prize in Chemistry in 1964. (Photo credit: Peter Lofts Photography, National Portrait Gallery, London Peter Lofts Photography, National Portrait Gallery, London ).
Mary-Claire King (1946)
Born: Illinois, United States. King is a human geneticist who studies the interplay between genetics and the environment on human disease. She is best known for having identified BRCA1, a single gene responsible for many breast and ovarian cancers. Her technique for identifying the BRCA1 gene is now used for studying many other diseases. She was also responsible for the development of a technique, using mitrochondial DNA and human leukocyte antigen, for genetically identifying the remains of missing people. (Photo credit: Mary-Claire King).
Born: United States. A key pioneer in the development of antibody engineering techniques, Morrison helped develop some of the first chimeric monoclonal antibodies. This work paved the way to the creation of safer and more effective monoclonal antibody drugs. (Photo credit: Sherie Morrison).
May-Britt Moser (1963)
Born: Fosnavag, Norway. Moser shared the 2014 Nobel Prize in Physiology or Medicine for helping to discover cells located in the centre of the brain that are important for determining spacial position. Her work has helped scientists gain new understanding into the cognitive processes and spacial deficits linked to neurological conditions like Alzheimer's disease. (Photo credit: NBC News).
Evelyn Witkin (1921)
Born: New York City, United States. Witkin is an American geneticist who is best known for her work on DNA mutagenesis and DNA repair. She helped elucidate the first co-ordinated stress response. This she did studying the response of bacteria to UV radiation. Witkins was one of the first few women to be elected to the US National Academy of Sciences, in 1977 and in 2002 was awarded the National Medal of Science. (Photo credit: YouTube).
Rosalyn Yalow (1921 - 2011)
Born: New York City, United States. The second American woman to ever be awarded the Nobel Prize for Physiology or Medicine, Yalow is best known for having co-developed a diagnostic technique, known as a radioimmunoassay, for measuring tiny quantities of various biological samples in blood and other bodily fluids. The test's primary detection mechanism is an antibody combined with a radioisotope. First devised for determining insulin levels in diabetes patients, the technique is now used for hundreds of other substances previously difficult to detect because they were too small. Among the substances it can quantify are hormones, vitamins, enzymes. It is also used to measure the effectiveness of dose levels of antibiotics and other drugs.
