जसले संसालई उज्ज्यालो बनाए - महान बैज्ञानिक थोमस अल्वा एडिसन || Life of Thomas Alva Edison

In 1878, Edison focused on inventing a safe, inexpensive electric light to replace the gaslight–a challenge that scientists had been grappling with for the last 50 years. With the help of prominent financial backers like J.P. Morgan and the Vanderbilt family, Edison set up the Edison Electric Light Company and began research and development. He made a breakthrough in October 1879 with a bulb that used a platinum filament, and in the summer of 1880 hit on carbonized bamboo as a viable alternative for the filament, which proved to be the key to a long-lasting and affordable light bulb. In 1881, he set up an electric light company in Newark, and the following year moved his family (which by now included three children) to New York. Though Edison’s early incandescent lighting systems had their problems, they were used in such acclaimed events as the Paris Lighting Exhibition in 1881 and the Crystal Palace in London in 1882. Competitors soon emerged, notably George Westinghouse, a proponent of alternating or AC current (as opposed to Edison’s direct or DC current). By 1889, AC current would come to dominate the field, and the Edison General Electric Co. merged with another company in 1892 to become General Electric Co.
