Frances Elizabeth Hoggan was a Welsh doctor and in 1870 became the first woman from the UK to receive a doctorate in medicine from any university in Europe. She was a pioneering medical practitioner, researcher and social reformer – and the first female doctor to be registered in Wales. She and her husband opened the first husband-and-wife medical practice in Britain. She was honoured with Wales' 11th Purple Plaque in her birth-town of Brecon in March 2023.

The Purple Plaques scheme in Wales, UK aims to install plaques on buildings to increase recognition of the lives of women who have had a significant and long-lasting impact associated with Wales.
