Painter; founder of the modern practice of art criticism and art historian who helped reassert the primacy of sixteenth- and seventeenth-century Dutch/Belgian masters. Fromentin's father, Toussaint Fromentin-Dupeux (d. 1867), was a doctor and amateur painter (trained under Jean-Victor Bertin), and his mother, Jenny Billotte Fromentin-Dupeux, the daughter of a Naval administrator and regional councillor in La Rochelle.

Curator of modern art at the Musées royaux des Beaux-Arts de Belgique (Royal museums of Fine Arts of Belgium). Legrand graduated in art history at the Brussels Institut supérieur d'Histoire de l'Art et d'Archéologie, located in the Royal museums of Fine Arts of Belgium. Between 1937 and 1939, under chief curator Léo Van Puyvelde, she served the museum as a guide and she delivered lectures, which activities were organized by the association of the Diffusion Artistique, founded in 1924.
