Before their marriage, Marie's mother called off her engagement with Hector Berlioz, inspiring Berlioz to elaborately plan to kill Marie, her mother, and Camille using two stolen double-barreled pistols, though he did not carry through with his plan.
Chopin's Nocturnes Op.
9 (1833) are dedicated to "Madame Camille Pleyel".
Camille and Marie separated after four years of marriage on account of her "multiple infidelities", and she went on to become a professor of piano at the conservatory in Brussels in 1848.
