The subject is Katie Gliddon (1883 – c. 1960), a watercolorist who studied at the Slade School from 1900 – 1904 and later exhibited widely. Gliddon was a suffragist who in 1912 served a short sentence at Holloway Prison for suffragist activity. She and Sickert’s sister Helena Swanwick, also a prominent activist, were both members of the Women’s Social and Political Union.
Two portraits of Gliddon by Edna Clarke Hall are in the collection of the National Museum of Wales, Cardiff (information kindly provided by Dr Anne Schwan, Edinburgh Napier University, and Beth McIntyre, National Museum of Wales).
