How much time did Thomas Alva Edison take to invent the first electric bulb?

It turned out that baking a piece of coiled cotton thread until it was all carbon was the winning filament. Inside a glass bulb that was almost a vacuum, it was able to stay lit for 13.5 hours. In the end, Edison’s “three or four month” project had taken him 14 months.
