Jean-François Pilâtre de Rozier (baptised 30 March 1754 in Metz, died 15 June 1785 in Wimereux /Pas-de-Calais) was a French chemistry and physics teacher, and one of the first pioneers of aviation.The son of an innkeeper, he botanized in the company of the duc de la Rochefoucauld, in the democratic companionship that early science fostered. His interests in the chemistry of drugs had been awakened in the military hospital of Metz, an important garrison town on the border of France. He made his way to Paris, then taught physics and chemistry at reims, which brought him to the attention of the king's brother, Monsieur, the comte d'Artois, who put him in charge of his cabinet of natural history and made him a valet de chambre to Madame, which brought him his ennobled name, Pilâtre de Rozier. Soon however he opened his own museum in the Marais quarter of Paris, researched the new field of gases and invented a respirator.
In June 1783 he was present at the unoccupied balloon ascension of the Montgolfier brothers. That September he sent aloft from the front courtyard of Versailles, in an untethered balloon, a sheep, a cockerel and a duck.

The form of the word may tempt one to think that "suburb" of Paris, attaining an altitudeAltitude is the elevation of an object from a known level or datum, called zero level''. Most often this level is defined as the absolute sea level, but it can vary. In aviation, the term altitude is used to describe elevation above mean sea level, the te of 3000 feet.
De Rozier died during an attempted crossing of the English ChannelThe English Channel is the part of the Atlantic Ocean that separates the island of Great Britain from northern France, and joins the North Sea to the Atlantic.

Thus, he and his companion, Pierre Romain, became the first known victims of an air crash .
The modern hybrid gas and hot air balloon is named the Rozier balloon after his pioneering design.
