Mario Cassoli from Carpi, a passionate collector of Marconian relics, in 1994 chose to donate to the Marconi Foundation the result of many years of patient and tenacious research. The scope of donating this “corpus”, up until then enshrined, was to consent a broader and more diffused understanding of Marconi's work.

As the Soresini collection, the Cassoli collection includes a heterogeneous set of materials (photographs, manuscripts, newspaper clippings etc). The cataloguing and filing of these sources has enriched the historical-biographical heritage relative to the figure of the Bolognese inventor.
