Domina Jalbert

Jalbert was married to Emma Rose Bourcier (1903–1994) on October 28, 1943, in Providence, Rhode Island.

He filed a patent in 1944 for a combination of a balloon with a stiffened flexible wing, forming what is now known as a "kytoon".

[5] In January 1963 he formally confirmed his discovery and invention of the ram-air double-surfaced fully flexible airfoil that would profoundly change kiting, parachuting, skydiving, hang gliding, paragliding, sport flying, power kiting, and more.

In 1964, he filed a patent titled "Multi-cell Wing Type Aerial Device" This would become key to paragliding, sky diving, powered paragliding, landboarding, kite surfing and cargo-ship kite tugging.

To slow the opening of the parafoil, Theodore ran the cords through rings he designed that were slid to the top while packing the parachute.

Every contemporary ram-air airfoil sport and utility wing began with Jalbert's invention.

[8] Jalbert invented his filed-for January 10, 1963 US Patent 3131894 the Parafoil which had sectioned cells in an aerofoil shape; an open leading edge and a closed trailing edge, inflated by passage through the air – the ram-air design.
