News to me until a friend re-tweeted this photo but there was a suffragette who trained in jiu-jitsu. Wikipedia tells me that “Edith Margaret Garrud (1872–1971) was among the first female professional martial arts instructors in the Western world. She is remembered for having trained the Bodyguard unit of the Women’s Social and Political Union (WSPU) in jujutsu self-defence techniques.“
What’s the plaque all about? Read the Guardian story Edith Garrud: a public vote for the suffragette who taught martial arts to find out about the woman who introduced jujutsu to the suffragette cause and how she came to be honoured with a plaque on her London house.
