Luigi Ferraro (3 November 1914, Quarto dei Mille – 5 January 2006, Genoa) was an officer of the Royal Italian Navy and pioneer of Italian submarine warfare, most notable for his service with the commando frogman unit Decima Flottiglia MAS.^[1] In 1943 in Turkey he attacked four ships carrying chromium ore.^[2] He was decorated with the gold medal for military valor for having sunk three enemy ships alone.^[3]: 5

Ferraro designed a number of innovations in scuba diving equipment for Cressi-sub, and in 1962 with Carlos Reinberg, he founded Technisub, a manufacturer of various underwater diving equipment.^[4]

Cressi made and launched Luigi Ferraro's two most important innovations during the early 1950s. One was the "Pinocchio" diving mask, the first mask with a rubber nose pocket enabling the fingers to pinch the nostrils, facilitating ear equalization. The other was the Cressi Rondine, the first swimming fin featuring a closed-heel foot pocket, a toe opening and a blade set at an angle from the plane of the sole of the foot, which improved both wearing comfort and hydrodynamic efficiency.
