The Edison Electric Illuminating Company
The Edison Electric Illuminating Company was a company owned by Thomas Edison. As Graham O'Brien noticed, Edison put his name all over his shop.
Nikola Tesla once worked for Edison. According to Edison, he was given a job on a factory floor. Tesla was able to fix Edison's generator, but he haven't received 50000 dollars that he was promised, so he left the job.
In 1903, Thomas Edison was giving a speech about alternating current in front of his company, when he was approached by Team TARDIS. Interested in a Silurian blaster he was shown, he invited them inside his company. While Edison and the Thirteenth Doctor were discussing recent attack on Nikola Tesla, his company was attacked by the Skithra. All his employees in the laboratory were killed, including Harold Green.
