Early meetings were held at the London coffee house on
Ludgate Hill. The institution chose its name after a property convenient for its needs was found: the
Rotunda Building on the south side of the
Thames, at the time part of the county of
Surrey. The architect employed was
Joseph T. Parkinson, son of
James Parkinson who owned the Rotunda, opened in 1787. The building had been the final home of the
Leverian Museum, housing the collection of Sir
Ashton Lever, but had fallen into disrepair. The Institution renovated it to include a large lecture hall capable of accommodating 500 people, and a galleried library of 60 feet in length; it opened on 1 May 1808. Other facilities in the building included committee rooms; a library with lending facilities; a reading room, chemical laboratory and contemporary philosophical apparatus. ==Staff==
