The lives of the first women doctors in Britain have been well studied by historians, as have the many debates about the right of women to train and practice as doctors.

In doing so, it reveals an identity that may seem at odds with some of the clichés of Victorian femininity, namely that of the intelligent and ambitious lady doctor.
