He worked for Edison.
The first slave arrived in the colonies in 1619 and was brought to work. As the colonies grew more slaves were needed to do the work.
In 1619 the first slave arrived and it grew from there when indentured servants didn't work out. When the cotton gin was invented the need for slaves became ever greater because more cotton could be grown, so by 1860 there were about 4 million slaves in the southern states.
He migrated to the US in 1884 being a 28 years old. As a matter of face, Tesla moved to New York because he could not develop his ideas. He was a Serbian American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current(AC) electricity supply system. Tesla gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric power development was involved in a corporate alternating current/direct current "War of Currents" as well as various patent battles.
The slaves were first brought to the American colones so that they could work in the fields and industries.
They needed workers. The first slave arrived in 1619. Indentured servants didn’t work out very well because they often disappeared among the colonists, but an African American in the colonies stood out. All African Americans were slaves, so they could be stopped and questioned if they were off of the plantation. The plantations were huge acres of land so many people were needed. By 1860 there were 6 million slaves in the south in slavery.
Nicola Tesla.
He worked with Edison.
He worked with Edison.
Tesla had it first. A mysterious fire put that on hold but it was known because he did lectures on the radio. Marconi used 17 patents granted to Tesla to make his radio. Tesla let him go ahead and work his company but the patent was granted to nikola Tesla.

He worked at Budapest Telephone Exchange where he made his first invention.
He got this work from 1885 to 1890.
It is a group on Facebook that promotes Nikola Tesla's work. There are many Groups and Pages about Tesla and Free Energy; which was his dream.
As early as 1892, Nikola Tesla created a basic design for radio. He knew Marconi used some 17 patents to make his radio but Tesla radio was a longer range compared to Marconis. Most of us, think of Guglielmo Marconi as the father of radio, and Tesla is unknown for his work in radio. Marconi claimed all the first patents for radio, something originally developed by Tesla. Anyway the patent was turned in Tesla's favor in 1943 after authorities had proof from documents. Tesla made the radio first, the rest was patent use.

She arrived in 1929 to work with the Sisters of Loreto.
Tesla could imaging things in his mind and put them to work.
