Luisa Locatelli does not directly benefit the Ospedale Maggiore directly, but her granddaughter Caterina Locatelli (1897-1983), names two grandchildren in equal parts in her will, but also assigns a conspicuous legacy in favor of the hospital, including the portraits of her paternal grandparents, Carlo and Luisa, that she kept in her Milanese house in Via Caravaggio 14.
