They were much safer than earlier light sources, and they made more activities, for both work and play, possible after the Sun went down.<\/p>\n<p>More than a century after its invention, illustrators still use a lit bulb to symbolize <a href=\"https:\/\/stock.adobe.com\/search?k=light+bulb+idea+icon\">a great idea<\/a>. Credit typically goes to inventor and entrepreneur <a href=\"https:\/\/education.nationalgeographic.org\/resource\/how-eureka-moments-science-happen\/\">Thomas Edison<\/a>, who created the first commercial light and power system in the United States. <\/p>\n<p>But as <a href=\"https:\/\/history.utk.edu\/person\/freeberg-ernest\/\">a historian<\/a> and author of a book about <a href=\"https:\/\/www.penguinrandomhouse.com\/books\/307057\/the-age-of-edison-by-ernest-freeberg\/\">how electric lighting changed the U.S.<\/a>, I know that the actual story is more complicated and interesting. It shows that complex inventions are not created by a single genius, no matter how talented he or she may be, but by many creative minds and hands working on the same problem. <\/p>\n<figure> <iframe loading=\"lazy\" width=\"440\" height=\"260\" src=\"https:\/\/www.youtube.com\/embed\/-Q4rQDN6Z4s?wmode=transparent&amp;start=0\" frameborder=\"0\" allowfullscreen=\"\"><\/iframe><figcaption><span class=\"caption\">Thomas Edison didn\u2019t invent the basic design of the incandescent light bulb, but he made it reliable and commercially viable.<\/span><\/figcaption><\/figure>\n<h2>Making light \u2212 and delivering it<\/h2>\n<p>In the 1870s, Edison raced against other inventors to find a way of producing light from electric current. Americans were keen to give up their gas and kerosene lamps for something that promised to be cleaner and safer. Candles offered little light and posed a fire hazard. Some customers in cities had brighter gas lamps, but they were expensive, hard to operate and polluted the air. <\/p>\n<p>When Edison began working on the challenge, he learned from many other inventors\u2019 ideas and failed experiments. They all were trying to figure out how to send a current through a thin carbon thread encased in glass, making it hot enough to glow without burning out. <\/p>\n<p>In England, for example, <a href=\"https:\/\/www.britannica.com\/biography\/Joseph-Wilson-Swan\">chemist Joseph Swan<\/a> patented an incandescent bulb and lit his own house in 1878. Then in 1881, at a great <a href=\"https:\/\/www.theiet.org\/membership\/library-and-archives\/the-iet-archives\/archives-highlights\/paris-electrical-exhibition-1881\">exhibition on electricity in Paris<\/a>, Edison and several other inventors demonstrated their light bulbs. <\/p>\n<p>Edison\u2019s version proved to be the brightest and longest-lasting. In 1882 he connected it to a full working system that <a href=\"https:\/\/www.nyhistory.org\/blogs\/edison-lit-manhattan\">lit up dozens of homes and offices<\/a> in downtown Manhattan. <\/p>\n<p>But Edison\u2019s bulb was just one piece of a much more complicated system that included <a href=\"https:\/\/www.asme.org\/about-asme\/engineering-history\/landmarks\/48-edison-jumbo-engine-driver-dynamo\">an efficient dynamo<\/a> \u2013 the powerful machine that generated electricity \u2013 plus a network of underground wires and new types of lamps. Edison also created the meter, a device that measured how much electricity each household used, so that he could tell how much to charge his customers. <\/p>\n<p>Edison\u2019s invention wasn\u2019t just a science experiment \u2013 it was a commercial product that many people proved eager to buy.<\/p>\n<h2>Inventing an invention factory<\/h2>\n<p>As I <a href=\"https:\/\/www.penguinrandomhouse.com\/books\/307057\/the-age-of-edison-by-ernest-freeberg\/\">show in my book<\/a>, Edison did not solve these many technical challenges on his own. <\/p>\n<p>At his farmhouse laboratory in <a href=\"https:\/\/www.menloparkmuseum.org\/history\">Menlo Park, New Jersey<\/a>, Edison hired a team of skilled technicians and trained scientists, and he filled his lab with every possible tool and material. He liked to boast that he had only a fourth grade education, but he knew enough to recruit men who had the skills he lacked. Edison also convinced <a href=\"https:\/\/www.britannica.com\/money\/J-P-Morgan\">banker J.P. Morgan<\/a> and other investors to provide financial backing to pay for his experiments and bring them to market. <\/p>\n<p>Historians often say that Edison\u2019s greatest invention was this collaborative workshop, which he called an \u201cinvention factory.\u201d It was capable of launching amazing new machines on a regular basis. Edison set the agenda for its work \u2013 a role that earned him the nickname \u201cthe wizard of Menlo Park.\u201d <\/p>\n<p>Here was the beginning of what we now call \u201cresearch and development\u201d \u2013 the network of universities and laboratories that produce technological breakthroughs today, ranging from lifesaving vaccines to the internet, as well as many improvements in the electric lights we use now. <\/p>\n<\/p>\n<h2>Sparking an electric revolution<\/h2>\n<p>Many people found creative ways to use Edison\u2019s light bulb. Factory owners and office managers installed electric light to <a href=\"https:\/\/stewartlighting.com\/2024\/03\/29\/how-light-bulbs-changed-the-world\/\">extend the workday<\/a> past sunset. Others used it for <a href=\"https:\/\/americanhistory.si.edu\/lighting\/19thcent\/consq19.htm\">fun purposes<\/a>, such as movie marquees, amusement parks, store windows, Christmas trees and evening baseball games. <\/p>\n<p><a href=\"https:\/\/www.britannica.com\/art\/stagecraft\/Stage-lighting\">Theater directors<\/a> and <a href=\"https:\/\/gamma-sci.com\/2020\/11\/16\/a-history-of-lighting-in-photography\/\">photographers<\/a> adapted the light to their arts. Doctors used small bulbs to peer inside the body during surgery. Architects and city planners, sign-makers and deep-sea explorers adapted the new light for all kinds of specialized uses. Through their actions, humanity\u2019s relationship to day and night was reinvented \u2013 often in ways that Edison never could have anticipated.<\/p>\n<p>Today people take for granted that they can have all the light they need at the flick of a switch. But that luxury requires a network of <a href=\"https:\/\/www.youtube.com\/watch?v=CHeMbhk4Mmw&amp;t=72s\">power stations, transmission lines and utility poles<\/a>, managed by teams of trained engineers and electricians. To deliver it, electric power companies <a href=\"https:\/\/mitpress.mit.edu\/9780262529785\/the-power-brokers\/\">grew into an industry<\/a> monitored by insurance companies and public utility regulators. <\/p>\n<p>Edison\u2019s first fragile light bulbs were just one early step in the electric revolution that has helped create today\u2019s richly illuminated world.<\/p>\n<hr>\n<p><em>Hello, curious kids!
