Eliza Walker Dunbar

The first woman in the UK to qualify and work as a doctor, says Wikipedia. Among other things, she established The Read Dispensary for Women and Children in Hotwells, so I'll have to see if I can track down where that was. It might, of course, have been in the bit of Hotwells that was demolished to make way for the flyovers, though.

Oh! No, a quick check seems to show that it's the building on St George's Road that now houses Oryx Recruitment. I know the building well.
