B
Leo Baekeland never gave up his dream of creating a special kind of plastic that would keep its form after it cooled. His invention was Bakelite，an inexpensive，widely used plastic.
Leo was born in Belgium into a lower, middleclass family. He studied at the University of Ghent in 1882 and eventually graduated with a doctorate in natural science at the age of 21. He taught there for several years before he traveled on a scholarship to the United States. Once in New York, Leo met Richard Anthony. Anthony saw potential in young Leo and offered him a job of working in America as a chemist for his company. Leo worked for Anthony for the next two years before unsuccessfully attempting to start his own consulting business.
After failing to see success in his own business operations, Leo decided to return to what he knew and he started producing a kind of photographic paper that would allow good pictures to be taken in artificial light. He did so well in the beginning that he started a company called Nepera Chemical Company while creating a special kind of paper called Velox. Within two years, Kodak Company bought the right to Leo's discovery for $ 1,000,000. Leo accepted and used the money to set up his own laboratory in his backyard in New York and lived a comfortable life.
Leo's next project was to come up with a hard yet moldable(可模压的)plastic. After much experimentation, Leo finally came up with a plastic and called it Bakelite. Its special feature was that at a high temperature and pressure, Bakelite can hold its form，even under great heat. Leo made his achievement public in February, 1909. The invention of Bakelite, marked the beginning of the Age of Plastics.
Whether we are listening to the radio，driving down the road, or drinking from our plastic bottles，we can thank a man who had the foresight and courage to pursue what he thought was possible.
