She was born in Gravesend, Kent. Her family moved to Hampstead in the 1890s. She was at the Slade
School in 1902 and 1903, and later studied with Max Bohm. In 1910 she was in Paris, where she
attended the Académie de la Palette, where she worked with Metzinger, J-E Blanche, and J. D. Fergusson. She did illustrations for the magazine Rhythm in 1911, but then moved back to London where she met Wyndham Lewis and joined his Rebel Art Centre, later signing the Vorticist manifesto and exhibiting with the Vorticists. She also published poetry and prose in Blast. During World War I she served as a volunteer in France, and after the war her work became more and more abstract. She was elected a member of the London Group in 1925, and showed with the Allied Artists' Association in their abstract show in 1937.

Modernism, Magazines, and the British avant-garde: Reading Rhythm, 1910-1914 by Faith Binckes covers Dismorr's connections with Anne Estelle Rice, J.D. Fergusson, et al and Rhythm magazine.  In Footnote 32, we find quotes from hard-to-find Dismorr gallery exhibition catalogues:

Jessica Dismorr   (London: Mayor Gallery, 1925)
In the catalogue notes to the one solo exhibition Dismorr held during her lifetime, R. H.
Wilenski commented upon the artist's "courage, discrimination,  and... sense of her ability to play a part in the most typical artistic experiments of her generation" . 'Foreword' , Jessica Dismorr (London: Mayor Gallery, 1925) (unpag.)

Jessica Dismorr, 1885-1939: Paintings and Drawings  (London  Mayor Gallery, 1965).
In a retrospective, also held at the Mayor in 1965, William Lipke observed that:

 "The significance of this exhibition is not confined to the obvious aesthetic merit to be found in these works, but includes as well the unique opportunity for the spectator to trace the development of British Art from the fauvist work of Rice, Peploe, and Fergusson ... Jessica Dismorr's work presents a continuity of effort which illustrates in capsule form the stylistic development of 20th century British art."  [from Binckes, Footnote 32]
