Henriette Renie was a creative and bold woman in the French musical world at the turn of the twentieth century. She began her career as a child prodigy on the harp, and the success she achieved from this enabled her to further her scope of interests into the fields of teaching and composing. As a concert harpist she elevated the status of the harp from an instrument for dilettantes to an important solo concert instrument. Quickly frustrated with the antiquated and limited repertoire that existed, she turned to composition. Her original works for harp are comprised of virtuosic compositions for her own performances and simpler pieces for beginning harpists. Renie also expanded the harp's repertoire by transcribing works for solo harp and harp ensemble. This thesis explores Renie as a performer, teacher, and composer, and analyzes two of her important compositions, Legende and Concerto in C Minor.
