First production of the Scaphandre Autonome (Aqua-Lung), patented in 1945, was delivered in 1946 under the name CG.45 (Cousteau Gagnan 45). Gagnan emigrated to Canada in 1947 where he worked for Canadian Liquid Air. After setting up a lab in Montreal, Québec, he continued to design and engineer scuba devices that would ultimately become the base models for most modern-day regulators.
