Witt emigrated to Australia and settled in Sydney in 1850 where he resumed his medical career. Within a short time however he was distracted to banking and speculation and at this occupation he made a fortune as a banker. Witt returned to the United Kingdom where he used his money to establish a new house near
Hyde Park. Witt now began to put together a collection of what would have been considered obscene objects. Witt was not concerned with the detailed provenance of these objects and he collected both ancient and modern items. Witt shared these objects with an international group of correspondents who appreciated these artefacts. In the 1860s there was a lot of interest in the theories concerning the worship of
Priapus and Witt organised for
Richard Payne Knight's
Discourse on the worship of Priapus and its connection with the mystic theology of the ancients to be republished with additional material and illustrations in 1865. Panizzi did not think twice as he considered the collection to be of the right quality for his museum. The collection appeared to be chosen primarily on the basis of its obscenity. The collection included modern photographs of women partially dressed as gladiators which were not thought to be academic artefacts but they were designed to be erotic. One of the artefacts was a toothed chastity belt which was thought to be medieval but was in fact a contemporary invention. In general however Witt's collection covered the major civilisations of Greece, Rome, Egyptian, Indian, Chinese, Tibetan, Japanese and Native American. Besides
votive objects, bronzes and pottery his collection also included watercolours and sketches. Of particular note were his library and the records of his correspondence which included the details of objects not in the collection including a catalogue of the
secret cabinet of Naples Museum. Following the acceptance of his collection by the British Museum in 1865, Witt published "Catalogue of a Collection Illustrative of Phallic Worship" in 1866 to commemorate the approval of his artefacts by Panizzi. ==Promotion of the Victorian Turkish bath==
