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.
[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.
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.
