I remember her well as a contemporary music 'fixture' from that era - the extraordinary time when William Glock was in charge of music at the BBC. How many pianists these days have a repertoire encompassing (at least) 184 composers? (my quick count of your incomplete list). What's striking in that list is not only her appetite for taking on anything and everything new, but also her exploration of unfashionable earlier byways - Reger, for instance. She must also have had Ogdonesque sight-reading powers.
