Henri Giffard (born February 8, 1825 – died April 14, 1882) was a clever French engineer. He is famous for inventing two important things in 1852. These were the steam injector and the very first powered Giffard dirigible airship.

Henri Giffard's Amazing Inventions
Henri Giffard was born in Paris, France, in 1825. He grew up to become an inventor. His two most famous inventions changed how we travel and use steam power.
The First Powered Airship
In 1852, Giffard created the world's first airship that could carry a person and be steered. It was called the Giffard dirigible. This amazing machine was filled with hydrogen gas, which made it float.
It had a special steam engine that weighed over 180 kilograms (about 400 pounds). This engine had 3 horsepower and powered a propeller, just like on a boat. To make sure it was safe, Giffard added a funnel pointing downwards. This helped stop sparks from the engine from reaching the hydrogen gas bag. He also put in a vertical rudder to help steer the airship.
The First Flight
On September 24, 1852, Giffard made history. He took his airship on its first controlled flight. He traveled about 27 kilometers (17 miles) from Paris to Élancourt.
The wind was very strong that day, so he couldn't fly back to where he started. But he could make turns and fly in circles! This proved that a powered airship could be steered and controlled in the air. It was a huge step forward for aviation.
The Steam Injector
Henri Giffard also invented something called the steam injector. He received a patent for this invention on May 8, 1858.
What's interesting is that Giffard figured out how the injector would work in his mind first. He had the whole idea explained in 1850, even before he built a working model. The injector is a device that uses steam to push water into a boiler. It's a very clever way to use steam power.
Honors and Legacy
In 1863, Henri Giffard was given a special award. He was made a Chevalier of the Légion d'honneur, which is a very high honor in France.
Henri Giffard passed away in 1882. He left all his money and property to France. He wanted his wealth to be used for good causes, like helping people and supporting science. His inventions helped pave the way for modern aviation and steam technology.
