In 1453, a shadowy, disagreeable man brought his new invention to a recently established commercial fair in Frankfurt. He had toiled tirelessly on his breakthrough idea in total secrecy for more than twenty years and gone deeply into debt to produce the prototype, forced repeatedly to ward off his creditors with assurances that he, and they, were on the verge of amassing a great fortune.
