I did know that Fanny was a composer, though I'd never played anything by her (hm, checking out your wiki link, probably because a lot of what she wrote was lieder or piano, and my piano repertoire is pretty limited), but I didn't know all that (or anything really) about her life. Wow. That's really interesting, and rather depressing in many ways, although according to the wiki article at least her husband seems to have supported her composing and publishing.
