[1] Delasalle first attended a convent school in Paris, the "Institution des Dames Augustines anglaises de Neuilly."

[2][4]In 1899 a state travel scholarship allowed her to paint in Italy, the Netherlands and England, where "she absorbed the influences of Rembrandt and Turner."

In the 1890s Delasalle expanded her subject matter from portraits to female nudes and she started showing her etchings in about 1904.

[3] She also became known for her rendering of landscapes such as Views from Greenwich Park and images of animals, in addition to scenes from the work world and portraits of other artists of her time such as Pierre Prins (1907).

[1][2][3] Her work was also featured in a 2003 exhibition in Bordeaux that traced the "emergence of prehistory as a scientific discipline and source of artistic inspiration," Musée d'Aquitaine.
