[5] Smythe had her first exhibition in 1896 at the Royal Academy[6] while she was living at the family home of Chateau d'Honvault, near Wimereux in Pas-de-Calais, France.
In 1904, it was noted by the Fine Art Society in London that her production was sparing, and her subjects were mainly of figures and landscapes from the Pas-de-Calais region.
[3] In 1905, her work A Cottage Girl was included in the book Women Painters of the World.
[10] After the death of their father in 1918, Smythe moved with her brother from France to London.
[1][11] The collection of the Royal Watercolour Society includes a work by Smythe entitled Gorse.
