The Institute and Museum of the History of Science (IMSS)

Florence, Piazza de' Giudici 1

Founded in 1927 at the initiative of the University of Florence, the IMSS played a determinant role in the realization of the First National Exposition of the History of Science held in Florence in 1929. The first exhibition halls in the IMSS were opened to the public in 1930, in Palazzo Castellani, a site it still occupies today, next to the Uffizi Gallery.

The collections of scientific instruments belonging to the Florence Institute and Museum of the History of Science are among the world's most important. These collections offer eloquent testimony of the scientific research sponsored first by members of the Medici dynasty, and then by the Grand Dukes of Lorraine. Starting with Cosimo I, the Medici Grand Dukes collected instruments of extraordinary beauty and innovative concept. The Medicean scientific collection was first kept in the Sala delle Carte in Palazzo Vecchio, and moved later to the Stanzino delle Matematiche and the adjacent Sala delle Matematiche in the Uffizi Gallery. Continuously enriched, these collections remained in the Gallery, alongside masterpieces of figurative art and of the most bizarre natural wonders, up to the mid-18th century, when the scientific collections were separated from the artistic ones.

Transferred to the Museum of Physics and Natural History, founded by Grand Duke Peter Leopold in 1775, the Medicean scientific collections were enriched by conspicuous acquisitions of new instruments and experimental apparatus. The Museum of Physics became, under its first director, Felice Fontana, an important structure for research and the spread of scientific culture. In 1841, on the occasion of the Third Congress of Italian Scientists, the Tribuna di Galileo was erected at the Museum of Physics and Natural History. In it were placed the most important instruments from the Medicean collection, next to those invented and used by Galileo and by the Accademia del Cimento.

In 1860, consequent to the Unification of Italy, the Museum of Physics and Natural History was suppressed. A great part of the collections was assigned to the Faculties of the Institute of Higher Studies. Only the ancient instruments and the zoological and anatomical collections remained in their original places. In 1925 the University of Florence was founded, and ownership of the scientific collections was transferred to it. To ensure their conservation and promotion, the Institute and Museum of the History of Science was founded in 1927. It took under consignment the collections of Medici-Lorraine scientific instruments, at its headquarters in Palazzo Castellani. Thanks to the dedicated commitment of the first directors, Andrea Corsini and Maria Luisa Righini Bonelli, the Florence Museum of the History of Science was progressively transformed into a center of conservation, promulgation and research of recognized international importance.

Over the last few years the museum's displays have been entirely redesigned. The library has  become the Italian center of reference for studies in the history of sciences and techniques and scientific museology. The Institute has held international seminaries and conferences, training courses and exhibitions destined to itineraries in the most prestigious sites. In addition, it has published a great number of volumes of research and promulgation. Its educational activity has been significantly developed, accompanied by the realization of innovative multimedia products distributed both on Internet and off-line.

At present, the exhibitions are displayed on two floors in Palazzo Castellani. The exhibition itinerary has been designed according to chronological and thematic principles. The first floor is  dedicated to the instruments from the Medicean collections, displayed in eleven rooms, in which can be seen, among other things, highly refined mathematical instruments, Galileo's original instruments (among them the only two telescopes surviving from among those personally constructed by the Pisan scientist), the instruments of the Accademia del Cimento and the extraordinary collection of terrestrial and celestial globes, dominated by the monumental armillary sphere of Antonio Santucci. In the ten rooms on the upper floor, evidences to the Lorraine age are displayed. They illustrate the notable contribution of Tuscany and Italy as a whole to the development of electricity, of electromagnetism and of chemistry, and display the complex clockworks of portable and tower-mounted clocks, an extraordinary series of obstetrical waxworks, the chemistry bench used by Grand Duke Pietro Leopoldo and, lastly, the beautiful and educationally effective machines for the demonstration of the fundamental principles of physics, constructed by the workshop of the Museum of Physics and Natural History.
