You probably don’t know much about her now, but spend 45 minutes in this small and well-designed biographical museum (on the grounds of the hospital with which she worked) and you’ll brim with newfound respect for this consequential person—as a founder of sensible nursing practices, as a leader who took no guff, and ultimately, as an all-around hard-core badass. It’s broken into three sections, attractively presented and with kid-friendly elements: her headstrong youth, her fame-making work whipping the troop hospitals of the Crimean War into shape, and her subsequent years of cranky reclusiveness and ceaseless writing.
