She exhibited at the Cercle artistique from 1894 to 1912.

Foni (Alphonse) Tissen (1909–1975) was a Luxembourg schoolteacher and artist who is remembered principally for his hyperrealistic, darkly humorous paintings, many of which were self-portraits.
Auguste Nicolas Trémont (31 December 1892 – 23 October 1980) was a Luxembourger painter, sculptor, and medallist. He specialised in sculptures of animals, with a particular emphasis on big cats.
Joseph Probst (1911–1997) was a Luxembourg painter who, in 1954, was one of the founder members of the Iconomaques group of abstract painters who opposed figurative art.

Will Kesseler (17 August 1899 - 24 September 1983) was a Luxembourgish painter, considered to be one of nation’s best Colourists.After having taught art, he left the country for the former Belgian Congo and Chad, where he was employed as a project manager for various railway construction companies. These periods abroad deeply influenced his very varied artistic production, which includes still life, flowers, Congo and Luxembourg landscapes, figures, nudes and abstract work.
After his rather academic beginnings, the artist, who twice received the Prix Grand-Duc Adolphe (1946 and 1950), turned in 1951 to abstract painting. His Africa inspired gouaches are characterised, as are his other paintings, by expanses of solid colours, pure, vigorous, intense and luminous with strong bold contrasts in which yellow, blue, red and above all contrasting greens dominate. Dynamic geometrical, curving and undulating shapes harmoniously intersect or are superimposed, giving familiar figurative glimpses of tropical vegetation.
Théo Kerg (2 June 1909 – 4 March 1993) was a Luxembourgian painter and sculptor who specialized in modern art.
