Brigitte Askonas, Austrian-English immunologist and academic (b. 1923)

Brigitte Alice Askonas (1 April 1923 – 9 January 2013) was a highly influential British immunologist whose pioneering research significantly advanced our understanding of the immune system's intricate response to viral infections. Her distinguished career spanned decades, marked by ground-breaking discoveries that laid foundational knowledge for modern immunology and continue to inform vaccine development strategies.

Brigitte Alice Askonas: A Pioneer in Cellular Immunity

Born on April 1, 1923, Brigitte Alice Askonas dedicated her life to the intricate study of immunology. Although born in Vienna, Austria, she became a British citizen and conducted the vast majority of her impactful research in the United Kingdom. Her work was instrumental in deciphering how the body's adaptive immune system, particularly T cells, combats pathogens like viruses, paving the way for clearer insights into immune protection and memory.

Foundational Contributions to Viral Immunology

Askonas is widely recognized for her seminal contributions to cellular immunology. For much of her illustrious career, from 1952, she was based at the National Institute for Medical Research (NIMR) at Mill Hill, London, eventually leading its prestigious Division of Immunology. Her research focused on critical areas, fundamentally altering our comprehension of how the immune system functions:

• Deciphering T Cell Responses: She was a pioneer in investigating the precise role of T lymphocytes, specifically cytotoxic T lymphocytes (CTLs), in recognizing and efficiently eliminating virus-infected cells. Her innovative methodologies for studying T cell function in vitro (in laboratory settings) and in vivo (within living organisms) were revolutionary, setting new standards for immunology research.
• Unraveling Viral Immunity Mechanisms: Askonas's extensive work, often involving crucial models like influenza virus and lymphocytic choriomeningitis virus (LCMV), provided unparalleled insights into how the immune system develops robust and long-lasting memory responses to viral pathogens. These findings are vital for understanding natural immunity and for designing effective vaccination strategies. Her research meticulously illuminated the specificity and long-term memory of cellular immune responses.
• Laying the Groundwork for Adaptive Immunity: Her cumulative discoveries contributed profoundly to the broader understanding of adaptive immunity – the sophisticated part of the immune system that 'learns' from past infections and 'remembers' specific pathogens to provide faster and stronger protection upon re-exposure. This knowledge forms the bedrock for contemporary vaccine science and the burgeoning field of immunotherapy.

Her profound impact on the scientific community was formally recognized when she was elected a Fellow of the Royal Society (FRS) in 1973, a testament to her exceptional scientific excellence and her leadership in the field.

Academic Engagement at Imperial College London

Following her formal retirement from the NIMR, Brigitte Alice Askonas maintained an active and influential presence in academia. She continued to contribute to scientific discourse and mentorship as a distinguished visiting professor at Imperial College London from 1995 until her passing on January 9, 2013. In this role, she generously shared her vast expertise, invaluable experience, and pioneering insights with new generations of researchers and students, further cementing her enduring legacy in the global scientific community.
