The balloon was invented by the Luso Brazilian priest (at 45 years of age) Bartolomeu de Gusmão (brother of the Luso Brazilian statesman Alexandre de Gusmão), and the first public exhibition was to the Portuguese Court on August 8, 1709, in the hall of the Casa da Índia in Lisbon.
The rubber balloon was invented by Michael Faraday in 1824; it was inflated with hydrogen and used in his experiments with that element. Rubber balloons were soon after sold for a penny a piece in parks and circuses in America. The more familiar latex balloons of today were first manufactured in London, 1847, by J.G. Ingram, but mass production did not occur until the 1930s
