The National Museum of Science and Technology (once Technics) “Leonardo da Vinci” was created on 15th February 1953. Today it is a Private law Foundation, whose institutional associates are Ministries, Public Bodies and Milan’s Universities. Next to its Chairmanship and Administration, the Museum is operationally developed by the Directorate-General. The Museum’s employees and collaborators design, develop and directly deliver day-to-day activities and extensive projects. Alongside with these internal resources there are also institutions, firms, professionals, researchers and experts, volunteers that complete the network through which the Museum achieves its mission. During more than 50 years of history, the Museum has gathered and preserved a remarkable heritage, documenting important stages of the scientific and technological development, with particular reference to our Country. The original museum project is focused on the topics of work and industrial production and it exhibits the collections in sections, according to a historical principle. The Museum preserves, studies and interprets the historic heritage, to make it accessible for the public. This heritage comprises the collections (15 thousand technical-scientific objects), the archive (paper and photos) and the library (40 thousand volumes and magazines) which witness the history of science, technology and industry, starting from the 19th century to the present, with particular reference to Italy.
