Which Woman Should Be on the Ten-Dollar Bill?

Although I have no say or justifiable concern about what another country chooses to do with their currency, I have seen some of the discussions and polls about this issue and I have to say that I don't know anything about most of the women I have seen suggested. It seems to me that there are very many deserving candidates, many of whom have not been suggested at all (and many whom even Americans would not recognise as having been influential). One woman who I feel should be honoured, however, is Rosa Parks, because she stood up for her own rights and for that of other black people by remaining seated in the bus where she had every right to be.
