On April 25, 1945 at 4:30 p.m. Grassi was seriously injured in a fight with German troops at the checkpoint of Via Lanzo in Turin and died the following day. He was initially employed at Bergougnan, subsequently at Superga and then at Pirelli.
His colleagues unveiled a memorial plaque in his honour, which is now preserved in the school that bears his name since 1978.
The state-run Industrial Technical Institute "Carlo Grassi" is located next to Piazza Stampalia in Turin, at the site where a large plaque with the names of 57 victims of Madonna di Campagna is placed on the building of the former Customs Duty Office.
