學(xué)習(xí)資料

  For years he lived in poverty, saving his money for his project. Fortunately, he succeeded in getting financial help from two businessmen in exchange for a two-thirds interest in his invention. With this extra money, Matzeliger finally achieved what he was after: A lasting machine that could turn out a complete shoe. His machine indeed changed the shoe industry. It not only greatly increased production but cut the cost of shoes by half. By 1889 the demand for the new lasting machine became worldwide.

  What was Matzeliger's reward? Because of his long and hard work and the lack of proper food and warmth during his years of poverty, his health had suffered. In the summer of 1886 he caught a cold which developed into tuberculosis. For three years he was so sick that he had to remain in bed. Finally, on August 24, 1889, he died at the age of thirty-seven.
