One November night in the year 1782, so the story runs, two
brothers sat over their winter fire in the little French town of Annonay,
watching the grey smoke-wreaths from the hearth curl up the wide chimney.
Their names were Stephen and Joseph Montgolfier, they were papermakers by
trade, and were noted as possessing thoughtful minds and a deep interest in
all scientific knowledge and new discovery.
Before that night—a memorable night, as it was to prove—hundreds of millions
of people had watched the rising smoke-wreaths of their fires without
drawing any special inspiration from the fact.
