![]() So, was Edison the sole inventor of the light bulb like he is given credit for? Absolutely not. Coolidge changed the carbon filaments to tungsten, resulting in a longer-lasting and brighter bulb. ![]() It became widely used and wasn’t changed again until 1911 when William D. Edison’s light bulb design took off, and eventually he adapted it to make it practical for daily use. Ī few years later, Edison bought Swan out of their company, known as Ediswan. Together, they became the Edison and Swan United Electric Light Company, Ltd. Edison lost the fight, leading to the 1883 merge of the Edison Electric Company and the Swan Electric Company. Swan’s light bulbs developed adequately as well, and the following year, in 1881, The Swan Electric Light Company was established.Įdison sued Swan after they mutually accused each other of patent infringement. patents for his now commercially viable light bulbs and established the Edison Electric Company. Both Edison’s invention and Swan’s invention were functional, but neither was ready for commercial use.īoth men continued to improve their inventions. The calendar clicked to 1880, and Swan presented a working lamp. On New Year’s Eve of 1879, Edison presented his team’s latest light bulb invention. He independently received a patent in the U.K. However, Edison and his team had competition.įrom England, Sir Joseph Wilson Swan was also working on creating an incandescent light bulb. He put together a team of 14 men called “the muckers” to help him out, and they got to work. Now, Edison was inspired to replace gas lights by creating an inexpensive, reliable, and safe incandescent light bulb in a six-week timeframe. Five years later, the Evans-Woodward duo gave up and sold their patent to Edison. Their light bulbs worked well but just weren’t selling. These men filed a patent in the United States and Canada for incandescent light bulbs with carbon filaments. Pressing forward to 1874, we introduce two men, Mathew Evans and Henry Woodward. His mercury vacuum pump system was such a success that it carries his name to this day. He removed the air from inside the electric bulbs, preserving the filament and eliminating the blackening problem. Twenty-four years later, in 1865, Hermann Sprengel, a German chemist, made a discovery. ![]() The air inside resulted in blackened burn marks on the glass bulb and rapid burnout. The bulb’s poor design only included a partial vacuum causing it to heat up too quickly. Unfortunately, the lamp wasn’t quite right. Frederick de Moleyns: 1841įast-forward through a slew of adaptations and other inventors to 1841 when Frederick de Moleyns received the first patent given for an incandescent lamp with a glass bulb in England. Here we’ll cover a few more of the notable names and events that led up to Edison’s fame. Although Davy’s light was not yet practical for commercial use, it started something life-changing. The original electric light was then created in 1802 by Sir Humphrey Davy of England. The first artificial light sources date back to the 1700s. A Brief History Lesson on the Invention of Light Bulbs Did Thomas Edison Invent the Light Bulb?Īlthough we’re taught in history that Thomas Edison invented the light bulb in 1879, the truth is that this invention was a complicated process involving many inventors across the globe for around 150 years. You may even learn some helpful tidbits you wish you knew before today. From their storied history to the best types of light bulbs to use in different situations, we’ll answer all of your bulb-related questions and more. If you’re looking for information about light bulbs, this detailed guide is for you. What’s considered to be the most valuable invention since human-made fire? The electric light bulb, of course! This significant development impacted the Industrial Revolution, allowing for longer working hours, safer evening travel conditions, and social order after dark.
