Filippo Negroli (ca. 1510–1579) was an armourer from Milan. He was renowned as being extremely skilled, and may be considered the most famous armourer of all time. Working together with his younger brothers Giovan Battista (ca. 1511-1591) and Francesco (ca. 1522-1600) in the Negroli family workshop headed by their father Gian Giacomo Negroli (ca. 1463-1543), Filippo was specialized in repoussé of armour, whereas his brother Francesco was renowned for his damascening skills.
