About the half of the XVII century the Pisa’s Gallery went through a period of decadence: in 1672 cardinal Leopoldo of Medici commissioned to the Danish Niccolò Stenone the writing of a brand new inventory of the objects in the Gallery, also giving him the task to choose and take “a few curiosities for the Gallery starting in Florence”.
By the end of the ’70, after the Carthusian Monastery of Pisa had been abandoned by the monk, professor Ezio Tongiorgi worked towards trying to have the prestigious monumental complex entrusted in perpetual free use to the University, so that it could be used to host the Natural History Museum, of which Tongiorgi cured the set up and the transport and of which he was director from 1977 to 1985.
