Nikola Tesla was born in the Austrian Empire in 1856 in what is Croatia today. His father was an Orthodox priest who wanted his son to enter the same profession but Nikola was only interested in science. His mother invented labour saving devices in her spare time and Tesla credited her as being the source of his inventiveness. Around the age of 17 he fell ill and was in bed for 9 months. His father promised to send him to the best science education if he recovered from the illness. He excelled in his first year at the Austrian Polytechnic in Graz earning the highest grades possible. He was fascinated by the mysterious phenomena of electricity in his classes and wanted to know more of this wonderful force. He worked incredibly hard, barely sleeping. A trait that he was to keep throughout his life. His teachers even wrote to Tesla's family warning that he could die from overwork. In subsequent years though, he lost his scholarship and became addicted to gambling, losing his entire allowance. Poor financial management was another trait that would hound Tesla in his later years. When it came time for his exams Tesla was unprepared. He asked for more time but it was refused. So he dropped out of his studies and never graduated. Tesla got himself back on his feet after a few years and started work at the Budapest telephone exchange as Chief Electrician where he invented and perfected a telephone amplifier. He then went to work for the Continental Edison Company in Paris. There he was working on a new innovation. Electric lighting. His skills got him noticed and soon he found himself heading to New York to work for Edison. In New York he was assigned to improving and repairing generators. After fixing the generators of the SS Oregon all throughout the night he happened to run into Edison. Edison joked, “I see our Parisian has been out all night!”. Tesla explained that he'd been working on the repairs for SS Oregon at which point Edison conceded to his colleague: "Mm, this is a darn good man!" Tesla started working on an arc lighting system for Edison. But it was never implemented. Tesla left their employment shortly afterwards. There was talk of unpaid bonuses and disparaging remarks from Edison. Tesla marked his departure by scribbling across two pages of his diary "Goodbye to the Edison Machine Works. Tesla founded his own company, Tesla Electric Light & Manufacturing and established a number of patents. Even though it had the Tesla name, the reality was that the company was financed by two businessmen. When they decided to abandon manufacture and set up a new company it left Tesla destitute and penniless. During 1886 he had to work as a ditch digger just to survive. He wrote of the time: “My high education in various branches of science, mechanics and literature seemed to me like a mockery” However Tesla soon got himself back on his feet with the invention of a new motor that ran on alternating current or AC which was eventually bought by Westinghouse. Tesla was a champion of AC and was hired by Westinghouse for $2000 per month and given a hefty bonus. Westinghouse Electric Company was founded by George Westinghouse and based their technology on AC. In the late 1880s and early 1890s a fierce commercial battle was going on between Edison and Westinghouse. Known as “The Battle of the Currents” many unsavoury publicity stunts were made by Edison trying to prove that AC was unsafe. But we'll not confront that particular Elephant in the room for now... Tesla became very wealthy and now had enough money to fund his own research, hiring staff and opening workshops. This was the golden age of Tesla's inventiveness. In 1891 at the age of 35 he became a US citizen. That same year he patented the Tesla Coil. He experimented with a system of wireless lighting. Giving several public demonstrations but he never received commercial backing for the project. At one demonstration he told onlookers that a system like this could transmit “intelligible signals or power to any distance without the use of wires”. The thought that wireless power could encompass the globe was an idea that Tesla devoted much time and research to. He started research on wireless telegraphy and in his laboratory observed strange signals which he thought came from another planet. He wrote to the press in 1899 and 1890 and an article was published entitled “Talking With Planets” More recently speculators think he may have unintentionally picked up signals from Marconi's experiments that were happening around the same time. Tesla threw his money into the wireless telegraphy research and borrowed heavily from JP Morgan. However Marconi's radio based system which Tesla thought was in part copied from his designs was the first to transmit a message across the Atlantic. After that, investors preferred Marconi's system… Which left Tesla once again without funds. In 1906 it's speculated Tesla had a nervous breakdown. From 1900 Tesla had lived in the Waldorf Astoria hotel. In 1922 he moved to the St Regis Hotel. Leaving his Waldorf Astoria bill unpaid. After that he moved from hotel to hotel leaving his bills unpaid. He liked feeding the pigeons from the windows of his hotel room. Despite issues with money he spent over $2000 building a device to heal the bones of a sick pigeon. He said: "There was one, a beautiful bird, pure white with light grey tips on its wings.
