The Frenchman was Jean-François Pilâtre de Rozier, who is often credited with being one of the first to fly in a hot air balloon. His fascination with ballooning contributed to the expression "to take the air," which refers to the act of flying or ascending into the sky. This phrase reflects the excitement and novelty associated with early balloon flights in the late 18th century. Pilâtre's pioneering efforts helped to popularize ballooning as a mode of flight.
