Who Invented the Light Bulb (Who Invented the Electric Light?)
Did Biden do it on purpose to woo black voters, or did he make his own mistakes because he didn’t understand the history of the invention of the electric light? Let us review the past and present life of the electric light together, and see how an electric light illuminates the history of more than one hundred years.
Biden made the above remarks while visiting Kenosha, Wisconsin. Source: AP: Did Edison really invent the light bulb? When it comes to the invention of the electric light, the first scientist we think of is Edison. More than 1,600 kinds of materials, such as copper wire and platinum wire, were used successively, and Japanese bamboo wire was finally determined as “durable filament”; 200 notebooks were used just to collect information; people spent years tirelessly inventing electric lights… We I am familiar with such stories. In fact, there are more “bright pioneers” behind the invention of the electric light.
Humphrey David Youyou Resource Network Source: Long before the incandescent lamp was born *** . In the early 19th century, the British Humphrey David used 2000 batteries and two carbon rods to make an arc lamp, which became the first arc lamp in the world. Although this carbon rod filament can emit bright light, the light is glare, consumes a lot of power, and has a short service life. However, David’s discovery laid the theoretical foundation for the invention of incandescent lamps and arc lamps.

He used a coil of metallic platinum as the filament and energized it with two lengths of copper wire (coated with an insulating coating). To avoid oxidation and cooling of the filament, he placed the filament in an inverted glass in water.

In 1878, the British vacuum technology continued to break through, and Joseph Swan finally invented a light bulb powered by carbon filaments in a vacuum environment, and obtained a British patent. Swan’s room also became one of the only private houses in Britain to be lit by electricity.
At the end of the 19th century, Edison showed his improved light bulb. Source: *** In 1874, two electrical engineers in Canada applied for a patent for an electric light: fill nitrogen into a glass bulb and use an electrified carbon rod to emit light. Due to lack of funding, the technology cannot be continuously improved. In 1875, they sold the patent to Edison. After obtaining the patent, Edison continued to try to improve the filament. After several years of repeated experiments, finally in 1879, Edison invented the high-resistance carbon filament true blank incandescent lamp and established a new normal-voltage power transmission system. In 1880, Edison and his team made aA carbonized bamboo filament lamp that lasts for 1200 hours. It lights one of the world’s most commercially valuable stable electric lights. Since then, Edison’s name has entered thousands of households along with electric lights.

In addition to being an inventor, another important identity of Edison was a businessman. In addition to his more than 2,000 inventions and more than 1,500 patents, Edison also founded the General Electric Company, which remains the world’s leading multinational corporation today. In 2020, General Electric, which has a history of more than 100 years, still ranks 77th on the 2020 Fortune Global 500 list. Who is Biden’s black inventor? In Kenosha, Wisconsin, on Sept. 3, Biden visited the family of Jacob Black, a black man who was shot seven times by police and was paralyzed, before meeting with community leaders to discuss institutionalized race issues such as doctrine. “Why don’t we teach history in history class? In fact, it was the black man who invented the light bulb, not the white man named Edison.” After the condolences, Deng Bai made this speech. One stone has stirred up thousands of waves, is there really such a person as Biden’s so-called black inventor Kong? Many media outlets claimed that the black inventor Biden was referring to was African-American Lewis Latimer.
Lewis Latimer (Lewis Latimer), a strange name, has been dusty in the history of electric light invention for a long time. Although he was not the inventor of the electric light, we cannot deny his efforts in improving it. Lewis Latimer was born in Chelsea, Massachusetts, on September 4, 1848. His parents were both fugitive slaves during the American Civil War. As the youngest child in the family, Latimer lived a nomadic life with his parents. Fearful of returning to the South and becoming a slave again, Latimer’s father hid in Islamabad and disappeared completely in 1857. and the invention of the light bulb. In 1864, 16-year-old Latimer lied about his age and joined the Navy in order to support his mother and family. After the Civil War, Latimer returned to Boston and accepted a humble position at the patent law firm of Crosby and Gould. Smart Latimer taught himself mechanical drafting by observing the company’s draftsmen at work. Recognizing Latimer’s talent and future, the company’s partner, Youyou.com, promoted him from handyman to draftsman. In addition to assisting with drafting, Latimer designed many of his own inventions, including improved bathrooms for railroad cars and early air-conditioning units.
Latimer was directly involved in one invention: *** . Worked with Latimer Bell to help draft the patent for Bell’s design. Latimer’s in-depth knowledge of patent filing and electrical engineering also led him to Edison perfecting the light bulband a close partner in patent filing. In 1890, Latimer also published a book called Incandescent Lighting: A Practical Description of the Edison System. It was not until 1922 that Latimer retired as a patent advisor at the age of 74. Lewis Howard Latimer died on December 11, 1928, in Flushing, Queens, New York, at the age of 80. At the beginning of the 20th century, carbonized filaments were replaced by tungsten filaments, and tungsten filament incandescent lamps are still in use today. Edison and his team invented the incandescent lamp, which was hailed as a revolution in the field of optics and stood in the field of lighting for a hundred years. Today, incandescent lamps with high energy consumption are gradually withdrawing from the stage of history and are constantly being replaced by environmentally friendly energy-saving lamps. Having said that, I believe everyone has a clear understanding of the question “who invented the electric light”. The electric light bulb was not invented at a certain point in time, but has gone through a long “history of invention”. Behind a small electric light is the painstaking efforts of countless inventors. There is nothing wrong with our textbooks. Edison is the brightest page in this “History of Invention”, and there are still many names behind him that we need to remember.
