It was Giescke who first referred to the museum as the "National Museum of Ireland" in 1832 in his catalogue of the entomology and ornithology specimens. After Giescke's death in 1833, John Scouler was appointed curator in 1834. During this time the collections were open to public two days a week from noon to 3pm, and to students at all times. By this time the need for a new museum was deemed to be critical. This led to the construction of the building which now houses the Natural History Museum on Merrion Street. With the planned expansion and development of the museum, Scouler requested that a curator or Director been employed by the RDS. This led to the appointment of Alexander Carte in 1851. Carte overhauled and reorganised the collections, overseeing acquisitions from Sir Francis McClintock, Sir William Wilde, and Sir Richard Griffith.
