Nikola Tesla - one of the greatest inventors in the history of mankind

The father of modern technology

Inventor, electrical engineer and physicist Nikola Tesla was born on 9/10 July 1856 in the village of Smiljan near Gospić. He comes from an Eastern Orthodox family, his father Milutin was an Orthodox priest, and his mother Georgina (Đuka) is from the priestly Orthodox family Mandić. He had three sisters, Milka, Angelina and Marica, and one brother, Dane.

His education began in his native Smiljan where he attended the local primary school and was taught German, arithmetic and religion, after which he attended the preparatory primary school and middle school in Gospić. After Gospić he moved to Rakovac in Karlovac where he finished secondary school (the Higher Real Gymnasium). He enrolled in the Austrian Polytechnic School in Graz with a scholarship from the Military Frontier, but after his scholarship was revoked due to the demilitarization of the Military Frontier, he was not able to finish his second year and he began to play cards and gamble to compensate for the financial loss, but in the end he gave up his studies before his third year. He worked for a short time in Maribor and after his father died in 1879, he worked in the secondary school (Real Gymnasium) in Gospić. In 1880 he tried to enrol at a university in Prague but failed, and a year later he found work in Budapest on the construction of the first telephone exchange.

Although I have to thank my mother for my inventiveness, the exercises that my father gave me were very helpful. They contained a multitude of tasks, e.g. guessing other people’s thoughts, detecting various errors or expressions, repeating long sentences or mental calculation. These daily exercises that had strengthened my memory and reason, and in particular helped me develop critical thinking, were undoubtedly very useful.

 

My mother came from one of the oldest families of this region, and we had invention running in our blood. Both her father and her grandfather invented many appliances for domestic, agriculture and other purposes. Indeed she was a great and extremely capable woman, brave and sure-footed, who rode the storms of her life and learned from those experiences. […] My mother was a first-class inventor who, I believe, would have achieved a lot if only she had not lived so far from modern life and the many opportunities it offered. She invented and developed many devices. She wove beautiful threads that she spun herself. She had even sown seeds, cultivated plants and separated the fibres from them. She worked tirelessly, from dawn until late at night, and much of the clothes we wore and the furniture we had in the house were handmade by her. Past the age of 60 her fingers were still so skilled that she could tie three knots with an eyelash.

Tesla worked for the Continental Edison Company in Paris, and in 1883 he constructed his first induction motor model in Strasbourg. After returning to Paris, Tesla received a recommendation from Charles Batchelor and moved to New York in 1884, where he was employed at Edison’s company. After a misunderstanding with Edison, Tesla left the company and founded his own in 1885, the Tesla Electric & Manufacturing Company. His company went bankrupt a year later and he had to do manual labour to survive. In 1887 Tesla founded the Tesla Electric Company and patented the following: the polyphase transmission of electricity, induction motor, generators and transformers. A year later, in 1888, Tesla entered into a partnership with George Westinghouse. He sold him patents for alternating current products for a million dollars, but only received USD 60,000 (as listed in some sources).

 

In 1889 he went back to Europe and visited his native Lika. This was his first trip to Europe since moving to the United States. In 1890 he began to research high frequency current and a year later he developed the Tesla coil (transformer). His second visit to Europe was in 1892 for his mother's funeral and at the time he also visited other European cities: London, Paris, Zagreb, Budapest and Belgrade. Tesla showcased the benefits of alternating current at the 1893 Chicago fair dedicated to achievements in electrical engineering. His laboratory was destroyed in 1895 so he was not able to publish his discovery of electrons and x-rays.

Tesla 1890
Napoleon Sarony

The door opens up and out steps a tall figure–over 6 feet tall-gaunt but erect. It approaches slowly, stately. You become conscious at once that you are face to face with a personality of a high order. A winning smile from piercing light blue grey eyes, set in extraordinary deep sockets, fascinates you and makes you feel at once at home. You are guided into an office immaculate in orderliness. Not a speck of dust is to be seen. No papers litter the desk, everything just so. Dressed in a dark frock coat, he is entirely devoid of all jewellery. No ring, stickpin, or even watch-chain can be seen. Tesla speaks a very high almost falsetto voice. He speaks quickly and very convincingly. After he speaks you find it difficult to take your eyes off his own. Only when he speaks to others do you have a chance to study his head, predominant of which is a very high forehead with a bulge between the eyes – the never failing sign of an exceptional intelligence. Then the long, well-shaped nose, proclaiming the scientist.

In 1896 the hydro-electric power plant on Niagara Falls which used Tesla’s AC patents was put in operation. Tesla was also the first to design wireless power transfer and in 1898 he demonstrated his remote control boat. He continued to research high frequency and high voltage currents and in 1899 he built a laboratory in Colorado Springs where he experimented with these currents. In 1900 he began to work on the World Wireless Broadcasting System on Long Island which he never finished because J. P. Morgan took away his funding. Tesla continued to work on his inventions and in 1907 he developed a bladeless turbine which he tested a year later. He pursued inventions related to mechanical engineering from 1910 to 1922.

 

In 1919 he published his autobiography, “My Inventions”. Tesla continued to patent various inventions such as vacuum patents, vertical take-off aircraft, etc. He also tried to improve the production process of sulphur, iron and copper.

 

In 1917 he was awarded the Edison Medal (the highest award of the American Institute of Electrical Engineers), and in 1926 he received an honorary doctorate from the University of Zagreb. In 1937 he received an honorary doctorate from the Austrian Polytechnic School in Graz. Tesla spent most of his life in hotels where he also died. He died aged 86 on 7 January 1943 in New York, in room 3327 on the 33rd floor of the New Yorker hotel.
