A plaque to celebrate biologist Dame Honor Fell, whose work led to an increase in understanding about rheumatoid arthritis, was unveiled before students from Banbury at Wychwood School.
It was unveiled last week by the Society of Biology.
Dame Honor (1900 to 1986) studied at Wychwood School and went on to develop the organ culture method, which allows scientists to grow living cells in the laboratory.
The plaque is one of ten around the UK celebrating unsung heroes of biology.
She was also director of Strangeways Research Laboratory at the University of Cambridge between 1927 and 1970.
Professor Doug Easton, co-director of Strangeways Research Laboratory, said: “Her legacy, both her research achievements and her ability to inspire future generations of scientists, has been immense.”
The Lord Mayor of Oxford, Mohammed Abassi, was also there.
