Dottore E. Frassi was an Italian doctor sympathetic to the partisan cause during World War II. Aldo often stole medicine from the Germans for him. He ended up being shot by German soldiers Hermann and Ehrlich along with Scarpi who raided his office looking for Turner.
- Frassi's name is not given in either the film or Michael Avallone's novelization. The credits of the former simply call him "Italian Doctor," while Avallone's book just calls him "doctor." However, his surname and first initial are visible on the sign outside his house.
