Henri Giffard, captive balloon, 19th century
Drawing by Albert Tissandler shows the balloon constructed by Giffard for the Paris Exhibition of 1867 and brought to London, 1868-69. Henri Giffard (February 8, 1825 - April 14, 1882) was a French engineer. He invented the injector and the Giffard dirigible, an airship powered with a steam engine, and weighing over 400 pounds. It was the world's first passenger airship. Both practical and steerable, the hydrogen-filled airship was equipped with a 3 hp steam engine that drove a propeller. On September 24, 1852 he made the first powered and controlled flight traveling over 16 miles from Paris to Trappes. He was able to make turns and circles, proving that a powered airship could be steered and controlled, but it was too slow to be effective. He was granted a patent for the injector in 1858. In 1878, he built a captive spherical balloon with a capacity of 25 litres, and a gondola accommodating 40 passengers. It was used to take aloft visitors at the International Exhibition in Paris. In response to his declining eyesight, he committed suicide in 1882, at the age of 57, leaving his estate to the nation for humanitarian and scientific purposes. His is one of the 72 names of scientists inscribed on the Eiffel Tower.
