问题     The following is a passage about inventors and their inventions.
    New inventions are appearing every day to make our lives easier, longer, warmer, speedier and so on. But only a few inventors design a new machine or product that becomes so well-known that the invention, named after its creator, becomes a household word. Here are four famous inventors and the inventions that are named after them:
    1. John Bowler, a London hatter who designed the hard round hat known as the bowler in about 1850. It has become the symbol of a respectable British man.
    2. Louis Braille(1809-1952), born in France. He was blinded as a child. In 1924 he developed his own alphabet patterns known as Braille by which the blind could read by touch.
    3. Rudolf Diesel(1858-1913), a German engineer who invented the diesel engine in 1897 and so began a transport revolution in cars, lorries and trains.
    4. Charles Rolls, a car salesman who with the engineer Henry Royce created the world-famous Rolls-Royce car.
