The  twelfth of fifteen children, Joseph was a dreamer and the first to  consider constructing flying machines. His youngest brother \u00c9tienne  provided the technical knowledge and skill to make Joseph&#8217;s dreams a  reality.<\/p>\n<p>In November 1782, while living in Avignon, Joseph  started experimenting with small models made of wood and taffeta under  which he lit a small fire. When the model rose, Joseph concluded that  the smoke from the fire contained &#8216;Montgolfier Gas&#8217; that had a special  property he called &#8216;levity&#8217;. This phenomenon had been known since 1709  when a Brazilian priest, Bartolomeu de Gusm\u00e3o, made a ball rise to the  ceiling of the hall of the Casa da India, Lisbon, in the presence of  King John V of Portugal. Despite being made a professor at the  University of Coimbra, de Gusm\u00e3o never developed a large scale  lighter-than-air-ship.<\/p>\n<p>Encouraged by his initial results, Joseph  Montgolfier sent for \u00c9tienne, who had trained in Paris as an architect  and thus had the ability to take Joseph&#8217;s experiments forward. Indeed,  within a month of the initial experiment, the brothers had constructed a  device with twenty-seven times the volume of the original model which  flew with such force that they could not maintain control of it. They  eventually found their experiment around two kilometres away.<\/p>\n<p>On  4th June 1783, the brothers were ready for their first public  demonstration. They readied their balloon in the marketplace at Annanoy.  The balloon was made from sackcloth, lined on the inside with layers of  paper and had a volume of 28,000 cubic feet. The enormous device drew a  sizeable crowd, including local dignitaries, who watched the ten minute  flight. The brothers became famous overnight.<\/p>\n<p>\u00c9tienne went to  Paris to conduct further demonstrations in collaboration with  Jean-Baptiste R\u00e9veillon, the famous wallpaper manufacturer. The result  was the <i>Aerostat R\u00e9veillon<\/i>, which flew in September 1783 carrying  a sheep, a rooster and a duck aloft watched by King Louis XVI, his  Queen, Marie Antoinette, and a very large crowd gathered at Versailles.  Two months later, following successful test flights with human  passengers in tethered balloons, Pilatre de Rozier and Marquis  d&#8217;Arlandes became the first humans to make an untethered balloon flight  from Ch\u00e2teau de la Muette, Paris.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Before the pioneering balloon flights of Joseph-Michel and Jacques-\u00c9tienne, the Montgolfier family of Vidalon, near Annanoy in south-eastern France, were best known as owners of a successful paper making business.
