The documents date from 1945, when the Institute became an independent board after sep- arating it from the CNR (Consiglio Nazionale delle Ricerche) to 1965. It is a decisive period for the ING, which had been founded in 1936 by Guglielmo Marconi, president of the CNR at the time and by the physicist Antoni- no Lo Surdo, who became its first director until his death in 1949. These valuable papers document how the ING rose from the war destruction, expanded its seismic monitoring network and developed experimental and theo- retical research in all the main fields of the Earth physics. Key words historical archives – Istituto Nazionale These archives include all the documents di Geofisica – geophysical research – Guglielmo produced by the Institute during its operating Marconi – Antonino Lo Surdo years from 1945 to 1965. 1.

The observatories were to be for the purpose of detecting as many observable natural phenomena as possible via the installation of various types of apparatus, and for carrying out experimental studies and research which would mark them as study centres; each would have a resident geophysicist as station director along with a support staff of technicians and assistants (ING, 1954). The stations were to be of a small- er size, with the installation of specialized in- struments regarding, among others, seismic, meteorological, and electricity studies. The sta- tions, for the most part, were run by a director, often a professor and in any case an expert in the field at hand, along with a technician.
