Edith Thompson was a housewife and milliner. She was executed on 9 January 1923 because her lover, Frederick Bywaters, murdered her husband Percy. She has an entry in the Dictionary of National Biography.
Their trial took place between 6-11 December 1922. Both were found guilty, the Crown "proving" her complicity through her surviving love letters to Frederick Bywaters. Innocent of murder, Mrs. Thompson was hanged for adultery.
Edith and Percy Thompson are pictured in the image to the left, dated September 1922
Both were hanged at the same time on the morning of 9 January 1923, she at Holloway and he at Pentonville.
Originally buried in the burial ground at Holloway Prison, her remains were removed to Brookwood (along with three other women executed at Holloway between 1903 and 1954) in 1971. The removal was necessary due to the complete rebuilding of the prison.
Her permanent memorial in plot 117 was placed there in October 1993 by a number of interested parties.
