When Edison was 29, the sale of an electrical-engineering firm holding several of his patents provided the funding to open his first development laboratory, in Newark, New Jersey.

A few years later, he moved to another location in New Jersey, what would become the famous Menlo Park facility, and later to a larger site in West Orange. Edison did some of his most significant work in those labs, developing the incandescent light bulb and the phonograph—his favorite invention.
