On February 26, 2020, within the celebrations of the Hundred Years of Psychology in Padua and in Italy, we should have celebrated Silvia De Marchi, a pioneer of experimental psychology who died prematurely. A day in the city where she worked, at the University of Padua, with exceptional participants including her granddaughter, the mathematician Leila Schneps. Unfortunately, the event was canceled due to the covid-19 pandemic. It seems that bad luck is raging on this exceptional woman.
