Lights on a Christmas tree may seem like a relatively recent phenomenon, but people who can’t wait to deck the halls each December may be surprised to learn that this beloved tradition dates all the way back to the late nineteenth century. Edward Johnson, a friend and colleague of Thomas Edison, introduced holiday light bulbs in 1882.
Prior to that, candles were lit on trees and families would briefly gaze at this awe-inspiring bit of holiday decor before the candles were quickly extinguished. Johnson is credited with being the first to suggest light bulbs, which were invented by his friend Edison, be used to light trees in place of candles. While many were impressed by Johnson’s eight-bulb holiday display, it remained a novelty until the 1920s, when preassembled lights became more accessible.
Since then, Christmas tree lights have taken hold as a must-have piece of holiday decor in households across the globe.
