Early in the beginning days of diving, Gustav created SCUBAPRO, the first company to seriously challenge Cousteau’s US Divers dominance in the industry. His company, through his ideas, elevated the dignity and popularity of diving everywhere, and his presence illuminated every affair that involved him.
He retired to create one of the world’s finest wineries, Dalla Valle Vineyards in Napa Valley, California. Gustav Dalla Valle was one of the most colourful and illustrious pioneers in the diving industry.
