The History of the Light Bulb
In 1809 a British Chemist named Humphry Davy began to concoct an iridescent light bulb. Davy used high battery power and two charcoal strips. This was the beginning of an invention that we today take for granted. The next step in the evolution of the light bulb was in 1820. A man named Warren de la Rue made a light bulb with a platinum coil in a vacuum sealed tube. This made a real electrical current! There were many other men involved in the invention of the light bulb, but there was one individual whom we all know that made the most lasting impact on the light bulb: Thomas Edison. In 1879, Edison made a new lamp made of a carbon filament. This burned successfully for thirteen and a half hours, later elongated to an amazing forty hours! Only a year later, Edison located a certain type of bamboo that was able to act as a filament. This change in filament enabled the new light bulb to burn for one thousand two hundred hours.
The Light Bulb Today
If it wasn't for that British Chemist, Humphry Davy, we would not have the modern light bulb we have today, and frankly, that we take for granted. From battery power and charcoal strips to magnetic currents and gas, our light bulbs have undergone tremendous changes. From the oil lamp in 1780 to our energy efficient curly light bulbs now, we can credit the light bulb to its original founders: Humphry Davy and Thomas Edison.
