Barbara Strozzi, Italian composer and singer-songwriter (d. 1677)
Barbara Strozzi (also called Barbara Valle; baptised 6 August 1619 – 11 November 1677) was an Italian composer and singer of the Baroque Period. During her lifetime, Strozzi published eight volumes of her own music, and had more secular music in print than any other composer of the era. This was achieved without any support from the Church and with no consistent patronage from the nobility.

Strozzi's life and career have been overshadowed by the claims of her being a courtesan, which cannot be completely confirmed as at the time female music making was often assumed to be an intellectual asset of a courtesan.
