    One <span>November</span> 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.
  </p>
  <p>
    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.
