In addition to those you've already had, Alma Mahler would be one from the "high romantic" era that you may enjoy?
There was a whole wave of female composers in the early Italian baroque, who are worth some time: Claudia Sessa, Francesca Caccini, Lucrezia Vizzana, Leonora Duarte, Barbara Strozzi... and several others. I would probably rate Strozzi as the most talented of them - she was certainly the most prolifically published, and appears to have lived from the financial proceeds of her works - making her the first known "commercially successful" female composer. Mostly they wrote in the
stile nuovo style (aka
seconda prattica in Monteverdi's terminology), and almost all of them were also the performers of their own work.
Barbara StrozziOn that theme, many other famous opera singers also composed - Colbran, Malibran, and Viardot all had published work (mostly in the art-song genre).
In my favourite period of the English Regency, there's also Marie Hester Park, an accomplished pianist who produced songs, incidental music for the theatre, chamber music (piano trios and other works) along with a body of now-lost works of unknown genre. (She wasn't related to either of the other "musical" Parks of the time, who were both oboists (and identical twin brothers)... her surname came by marriage to the author Thomas Park).
Oh, I suppose someone ought to mention Hildegard von Bingen - she mustn't be omitted. Nor should Dame Ethel Smythe for that matter.
