Eva Callimachi-Catargi (May 10, 1855 – May 29, 1913) was a Parisian heiress known for being the subject of two paintings by Henri Fantin-Latour.

[1] Eva immersed herself into the art scene of Paris during the Belle Époque period, and modeled various works of art most famously two paintings by Henri Fantin-Latour Drawing lessons in the workshop (1879) and Portrait of Eva Calimachi-Catargiu (1881).

Eva was a personal friend of Henri and many talented artists of the time including composer Ernest Chausson, and sculptor Auguste Rodin.

When Nicolas died in 1963, his widow Lascelle Jean Meserve donated his family's papers including personal notes to Stanford University.

The Hoover Institution founded The Nicolas de Basily Room for its permanent exhibit on Russian culture.
