Author Claire Tomalin has unveiled a blue plaque in honour of the early feminist writer Mary Wollstonecraft.
She left in 1791 just before the publication of her most famous work The Vindication of the Rights of Women. Before pulling the curtains aside, Tomalin reminded the audience that Mary's daughter Mary married Percy Bysshe Shelley and wrote Frankenstein.
Number 45 is now a 20th-century building but Thompson House next door would have been known to Mary Wollstonecraft.
• Claire Tomalin is Mary Wollstonecraft's biographer. The Life and Death of Mary Wollstonecraft (Penguin £9.99) won the Whitbread First book Prize. Last year she won the Whitbread Book Award for her biography of Samuel Pepys.
• Mary Wollstonecraft's son-in-law, poet Percy Bysshe Shelley, lived in nearby Nelson Square where there is a plaque marking the site.
