Ask anyone about the invention of the light bulb, and most people will immediately think of Thomas Edison. It's a captivating story that embodies the American ideal of individualistic innovation. But the truth is, the invention of the light bulb was a collaborative effort involving numerous inventors over several decades. Let's take a closer look at some of the key players in this groundbreaking achievement.
Swan's Light Bulb
One of the inventors who contributed significantly to light bulb technology was Joseph Swan. In the mid-19th century, Swan, a chemist from England, set out to create a more affordable light bulb. He replaced the previously used platinum filaments with carbonized paper filaments. While Swan's carbonized paper filaments worked well in demonstrations, they weren't practical for everyday use as they burned out too quickly.
Despite this setback, Swan's work paved the way for further improvements in light bulb technology.

Edison's Light Bulb
Contrary to popular belief, light bulbs existed before Edison's time. However, one of his notable contributions was building upon Joseph Swan's incandescent light bulb. Edison made the filaments thinner, increasing their electrical resistance and requiring less current to produce light. In 1879, he publicly demonstrated his refinements, which Swan quickly adopted. Swan then established an electrical lighting company in the U.K.
Edison attempted to sue Swan, but Swan's patent in the U.K. was ironclad. Instead, the two inventors joined forces, forming Edison-Swan United, which eventually became one of the largest light bulb manufacturers worldwide. Although Edison is often credited as the sole inventor of the light bulb, he actually acquired the patent rights and improved upon the existing design to make electric light accessible to the general public.
Nevertheless, Edison faced the challenge of bringing electricity into American homes.

Tesla, the Light Bulb, and Electric Current
Nikola Tesla, born in Europe in 1856, migrated to the U.S., where he caught Edison's attention. Tesla contributed innovative ideas to Edison's inventions, but their collaboration was short-lived. The most significant point of disagreement between the two inventors centered around electric current.
Edison championed direct current (DC) as the ideal method for delivering electricity to homes. However, Tesla believed that alternating current (AC) was superior and advocated for its use. With his invention of the induction motor, Tesla demonstrated that AC could sustain and regulate higher voltages effectively.
Edison and Tesla engaged in a fierce feud to prove the superiority of their respective theories. In the end, Tesla's AC system prevailed, and it became the standard for electrifying America.
