Nikola Tesla

Nikola Tesla was a Serbian-born engineer, inventor, and futurist who immigrated to the United States to work for Thomas Edison. He soon left his mentor and secured his own funding to pursue his findings and inventions in electrical current and bring electricity to the masses.

Tesla even devised a method to provide unrestricted, cost-free power from the ground, but his dream was never realized since it was not commercially viable. He was unquestionably one of the most significant thinkers in the field of invention during the 20th century, and his electrical discoveries were far ahead of their time. Even now, the technology he discovered is still in use.
