However, when it got dark, many people used other sources of light, such as: candles, lanterns, oil lamps, and light from fireplaces!<\/strong> <\/figcaption><\/figure><\/div>\n\n\n\n<p>You may have heard the name \u201cThomas Edison\u201d many, many times. There\u2019s a reason why he is mentioned often. Edison was one of the greatest American inventors. He invented the phonograph (something that played music), and the first motion picture machine. However, many people argue that his greatest contribution was perfecting the light bulb. Edison\u2019s work allowed more people to work at nighttime, stay awake longer, and read more.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">WHY INVENT THE LIGHTBULB?<\/h2>\n\n\n\n<p>Remember when you closed your eyes and imagined a world\nwithout electricity? It felt strange, right? Perhaps, even scary? Before the light\nbulb many people were scared of the dark as well. After the light bulb was\nperfected in 1879, people felt safer at night. Before the light bulb, people\nused candles or lanterns for light at night. Candles are incredibly dangerous\nbecause they easily start fires.&nbsp;<\/p>\n\n\n\n<p>Scientists thought electricity could solve this problem.\nElectricity creates sparks. And, when certain conductors get hot, they also\ncreate light. Electricity does not involve a flame. It seemed like a natural\nfit. But, using electricity to create light was difficult! Who could solve this\nproblem?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PERFECTING THE LIGHTBULB<\/h2>\n\n\n\n<p>Thomas Edison was very active and learned a lot as a child.\nHe also questioned everything around him. He drove his school teachers nuts! As\nan adult, he became interested in electricity, and eventually started his own\ncompany in 1878. He called it the Edison Electric Light Company. Despite what\nsome people think, Thomas Edison did NOT actually invent the light bulb. In\nfact, 23 light bulbs were invented before Edison made his. BUT, he was the\nfirst to create a light bulb that would be sold to most Americans. To learn\nmore about this light bulb, check out chapter 6!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">JOSEPH SWAN WHO?<\/h2>\n\n\n\n<p>Ok&#8230;So, if Thomas Edison did not\ncreate the first light bulb, who did?<\/p>\n\n\n\n<p>A scientist named Joseph Swan invented the light bulb in\n1878. Swan patented his light bulb in England (a patent stops other people from\nstealing an inventor\u2019s idea). Swan used a carbon rod in his light bulb. The\ncarbon resisted electricity. When the carbon resisted electricity heat and\nlight was released.<\/p>\n\n\n\n<p>Swan started his own company of light bulbs. Swan\u2019s light\nbulb produced light, but did not last very long. Carbon was also dirty so it\nmade the inside of the light bulb dirty which trapped the light. Carbon rods were\nnot the solution, but it was a good start.<\/p>\n\n\n\n<p>Without Thomas Edison perfecting the light bulb, we may not be able to experience electricity the way we do today. Because Edison changed the light bulb so it would be commercially successful, reliable, and practical, he is given credit for perfecting the light bulb.&nbsp;<\/p>\n\n\n\n<p><a href=\"http:\/\/myedme.com\/loginEIE0E\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Click here to answer questions about this chapter.
