Strictly speaking, however, Self-Contained Underwater Breathing Apparatus, or SCUBA, using pressurized (150 atmospheres/approx 5300(!!!)lbs) air with a downstream user-demand regulator valve can be very closely dated. In his (highly reccomended) 1953 book, "The Silent World", Capitaine Jacques-Yves Cousteau describes how, in June, 1943, he first tested (his own design of) the world's first (23kg) 'aqualung', accompanied by Phillipe Taillez as (surface) dive-boat 'tender' and Frederic "Didi" Dumas as 'safety' (skin) chase diver. Capitaine Cousteau's wife, Simone was to observe only, using mask and schnorkle.
