At the behest of Grand Duke Peter Leopold, the scientific collections gradually accumulated in the Pitti Palace by the Medici were transferred to the Regio Museo di Fisica e Storia Naturale in 1775. Thanks to the dynamism of the Museum's director, Felice Fontana, and the competent work of many craftsmen, the Museo saw a steady increase in the number of scientific instruments, including machines for demonstrating the basic laws of physics, electrical machines, meteorological instruments, and measuring instruments. Even the natural-history collections in the Uffizi Gallery were transferred to the Regio Museo. They formed the first nucleus of holdings that were systematically expanded during the 19th C. Fontana and his colleagues also worked unstintingly to form a collection of waxes on human anatomy. In 1775, year of its foundation, fully six rooms of the Regio Museo were already entirely dedicated to anatomical waxes. The Museum also built three wooden anatomic statues, one of which, on Napoleon Bonaparte's orders, was shipped to Paris in 1806. In the 19th C., the collections of instruments, natural-history specimens, and anatomical waxes were thoroughly catalogued and substantially enlarged through new acquisitions. After Italian unification, the collections were broken up and distributed among the departments of the Istituto di Studi Superiori. In 1925, the scientific and natural-history collections went to the University of Florence. In 1927, the University created the Istituto e Museo di Storia della Scienza, which it endowed with the old Medicean and Lorraine holdings of physical and mathematical instruments.
