From Louisville to Light Bulbs: Thomas Edison’s KY Connection

Our lives would be so much dimmer if it weren't for Thomas Edison and the incandescent light bulb. Did you know that Kentucky played a significant part in sharing this invention with the world, and Edison actually lived in Louisville when he was a young man?

Thomas Edison Once Lived in Louisville, KY

In 1866, when Thomas Edison was 19 years old, he moved to Louisville and worked as a telegraph key operator. He was very skilled, and apparently, there was an operator shortage at the time, so he was quickly hired by Western Union.  Edison was fascinated with improving the telegraph and learning the ins and outs of electricity.

During this time, he rented the front room of an old house on Washington Ave in the Butchertown area. Working for the Associated Press wire, he took the night shift. This allowed him some privacy to pull double duty and conduct experiments at work.

While handling a vial of sulfuric acid one evening, he accidentally spilled it, and it leaked through the floorboards onto his boss's desk. As you can imagine, this did not go over well, and he was fired! Thomas Edison then moved to New Jersey to continue working on his inventions in his famous Menlo Park laboratory.

While Edison did not invent the light bulb, he made improvements to the type of filament used, which made the bulbs last longer and more cost-efficient. As well as developing a generator to run the electricity. Because of this, he ended up back in Louisville, Kentucky, sixteen years later, for the Southern Exposition.

The Southern Exposition was a series of World's Fair events over the span of five years. Located in the Old Louisville area, it showcased achievements in art, music, industry, horticulture, etc., but before Thomas Edison's Electric Light Company came to town, it could only be hosted during the day.

The Louisville Board of Trade contracted with them for the largest display of incandescent lights at the time. Five thousand bulbs lit up the Expo in the evening so more people could enjoy the events. In fact, in the first 88 days, 770,048 people were recorded to have attended!

The inside also houses a museum of artifacts and iconic inventions that he very well could have dreamt of while sleeping in his tiny bed right here in the heart of the Bluegrass State. Volunteers host tours upon request by visiting historichomes.org. Here is a small peek at what it looks like.
