Man or woman? Does it matter? At the time it did. In 1843 Fanny Mendelssohn (1805–1847), Felix Mendelssohn’s sister, wrote an outstanding piano work, the Piano Sonata in G minor (H-U 395). But her family had made clear that her compositions should not be published and that she should not perform in public. She was meant to be a distinguished lady, a good housekeeper and a caring mother. This didn’t keep Fanny Mendelssohn from composing, nor from publishing her works for that matter and she could count on the support of another man, her husband. As much as Fanny loved Felix, she had a brain of her own and knew how to use it.
