For many years Leblanc was the lover of Belgian playwright and writer Maurice Maeterlinck, and he wrote several parts for her within his stage plays.

Georgette Leblanc was born into a cultured family that valued the arts of all forms and encouraged her to pursue music, acting, and writing.

She initially worked for a short time as an actress on the Paris stage before studying music under Jules Massenet in that city.

Leblanc had married a Spanish man a few years previously, and the Roman Catholic Church refused to give her a divorce from her unhappy marriage.

The couple's home became a center for the artistic community with individuals like Octave Mirbeau, Jean Lorrain, and Paul Fort frequently being entertained at their house.

[3] Beginning with Aglavaine and Sélysette in 1896, she began to appear in a number of Maeterlinck's plays, several of which included characters specifically written for or based on her.

She also sang in a number of recitals and concerts in Paris that included German lieder by Franz Schubert and Robert Schumann that had been translated into French by Maeterlinck.

She continued to be popular among the Parisian artistic social circles and was notably friends with Jean Cocteau and Marcel L'Herbier, in whose film L'Inhumaine (1924) she starred.
