- In 1876, Edison moved his expanding operations to Menlo Park, New Jersey, and built an independent industrial research facility incorporating machine shops and laboratories.
- In December of 1877, Edison developed a method for recording sound: the phonograph.
- While Edison was not the inventor of the first light bulb, he came up with the technology that helped bring it to the masses.
- Edison was driven to perfect a commercially practical, efficient incandescent light bulb following English inventor Humphry Davy’s invention of the first early electric arc lamp in the early 1800s.
- After buying Woodward and Evans’ patent and making improvements in his design, Edison was granted a patent for his own improved light bulb in 1879.
- In January 1880, Edison set out to develop a company that would deliver the electricity to power and light the cities of the world.
