Industrialist Joseph Heinrich Mayer met Seraphine Sebrechts when he hired her to be his invalid first wife’s musical companion. After the first Mrs. Mayer died, Seraphine became the second, and in 1903, the newlyweds had a daughter named Frédérique Mayer.
Riki (as she was nicknamed) seized every privilege of her upbringing, throwing herself into her studies with aplomb and enrolling at the Royal Conservatory in Brussels. (She had seen how her pianist / composer / painter / photographer mother’s talents had been suppressed, and she was determined not to let her own go to waste.) In 1923 Frédérique emigrated to the United States, where she began pursuing her penchant for conducting at New York University.
A decade later, in 1933, she and her journalist husband Peter Petrides decided to found a women’s chamber orchestra: the Orchestrette Classique. Peter was named the Orchestrette’s manager and publicist, while Frédérique became its music director.
