John Thomas Quekett (1815 - 1861) was a pioneering histologist. His brother Edwin lived at 50 Wellclose Square. John moved in with his brother. In 1839 John founded the Royal Microscopical Society. He was conservator of the Hunterian Museum until his death. Dr Nathaniel Bagshaw Ward (1791 - 1868) invented the terrarium (a dry version of an aquarium). He invented it about 1829, because his ferns were being poisoned by the London air. It also went by the name Wardian case.
