Thomas Harris (died 25 May 1824) was a pioneering English balloonist who was killed in an accident. There is little information about his early career, but he invented the gas discharge valve, a device to release all the gas in a gas balloon to prevent the balloon from dragging after landing.[1]
Thomas Harris was an inventive London scientist and held the military rank of Lieutenant.[2][3] He exhibited a hydrogen balloon at the Royal Tennis Court in Great Windmill Street, Haymarket, in the spring of 1824. While not a professional aeronaut, he may have planned to become one.[1]
In 1823, Harris made successful experiments on the River Thames with a view to preventing ships from being struck by lightning.[4]
Harris invented the first mechanism for emptying a balloon canopy of gas or hot air, thus reducing the drag on landing.[5] He designed a double valve, located at the top of the balloon bag, with a small valve fitted inside a larger one. One was for releasing the gases slowly, the other quickly.[3] Harris commented that "The science of aerostation has lately fallen into much decay and been the subject of ridicule through the total want of invention".[6]
