Henri Giffard,French engineer
Henri Giffard (1825-1882),French engineer,historical artwork. Giffard was the inventor of the first navigable,passenger-carrying airship in 1852. The steam-powered,lighter than air craft was 43 metres long and was called a dirigible. The dirigible was filled with hydrogen and flew at about 8 kilometres per hour (5 mph). It was not,however,until the invention of the gasoline-powered engine in 1896 that practical airships of a similar design could be built. Giffard also invented the injector,which fed water into a steam-engine boiler to prevent it running out of steam when not in motion
