In 1783, the Montgolfier brothers, pioneers in aviation, showcased the first public demonstration of hot-air balloons in Annonay, France. Concurrently, Jacques Charles, along with the Robert brothers, launched the first hydrogen balloon in Paris. The balloon race continued with innovative flights, including the first living creatures sent airborne by the Montgolfier brothers. Jean-François Pilâtre de Rozier and François Laurent d’Arlandes achieved the first free flight on a hot-air balloon, followed by Charles and Nicolas Robert's successful free flight on a hydrogen balloon. Charles' groundbreaking work not only enabled manned flight but also provided crucial meteorological data. The process of filling the balloon with hydrogen gas was a remarkable feat, involving a chemical reaction with concentrated sulphuric acid and iron nails. Despite the flammability of hydrogen gas, the flights concluded safely, contributing to the popularization of balloonomania. This era of balloon fascination, coined balloonomania, had a profound social impact, igniting public interest in science and technology. Balloons became a symbol of progress, leading to cultural trends and societal change. Jacques Charles' contribution not only revolutionized aviation but also advanced gas physics with the formulation of Charles's Law, immortalizing him in the history of science and technology.
