Lever began by collecting seashells in about 1760, and gradually accumulated one of the richest private collections of natural objects, including live animals. He opened it to the public in April 1766, in Manchester, moving the museum to his family home at Alkrington Hall, near Rochdale, Lancashire, in 1771. In the same year he founded Archers' Hall, Inner Circle, Regent's Park, London for the Archers' Company of the Honourable Artillery Company. In 1774, Lever moved to London, and next year his Holophusicon opened to the public in Leicester Square. Captain James Cook was impressed by Lever's collection, and donated objects from his own voyages to the museum.
