Joseph Swan

Joseph Swan was a British physicist and inventor who developed one of the first practical electric light bulbs in the 1860s-1870s. His design used a carbon filament in a vacuum to produce light when electric current passed through it. Although his early versions weren’t commercially successful, he continued refining the technology, and in 1878, he demonstrated a working bulb. Swan’s advancements contributed significantly to the development of electric lighting, paving the way for the widespread use of electric light in homes and industries. His work was later recognized globally, and he shared the first electric lighting patent with Thomas Edison in the UK.
