Early Life
Nikola Tesla was born on July 10, 1856, in the village of Smiljan, then part of the Austrian Empire. His father, Milutin Tesla, was a priest in the Serbian Orthodox Church, while his mother, Đuka Mandić, was highly gifted and known to create household tools and mechanical devices. Tesla often credited his mother’s creativity as a major influence on his own genius.
As a child, Tesla displayed extraordinary memory and an unusual imagination. He could visualize inventions before building them, a skill that stayed with him throughout his life. He was deeply curious about nature, electricity, and the mechanics of the world.
Age
Nikola Tesla lived from 1856 to 1943. He died at the age of 86.
Education
Tesla attended the Higher Real Gymnasium in Karlovac, where he excelled in mathematics and physics. He later studied at the Austrian Polytechnic in Graz, showing exceptional ability in engineering. Tesla also attended Charles-Ferdinand University in Prague for a short period. Although he did not complete his degree, his brilliance was undeniable and recognized by professors and colleagues.
Tesla’s education extended far beyond formal schooling. He read widely, studied languages, and mastered multiple scientific fields independently.
Early Career
Tesla began his professional journey working for a telegraph company in Budapest, where he first conceptualized the rotating magnetic field — the foundation of alternating current (AC). He later moved to France, working for the Continental Edison Company, where he repaired and improved electrical equipment.
His skill caught attention, and he was soon invited to work for Thomas Edison in the United States. Tesla arrived in New York in 1884, ready to share his revolutionary ideas.
Career & Major Contributions
Alternating Current (AC) System
Tesla’s most influential contribution is the development of the AC electric power system. His multi-phase AC induction motor and transformer allowed electricity to travel long distances efficiently — something direct current (DC) systems could not achieve.
His partnership with George Westinghouse played a key role in adopting AC electricity across America, eventually leading to the modern power grid we use today.
The Tesla Coil
One of Tesla’s most iconic inventions, the Tesla coil, demonstrated wireless transmission of energy. The coil was used in early radio technology and continues to be used today for scientific experiments and educational demonstrations.
Radio Technology
Although others received credit at first, Tesla’s inventions laid the foundation for radio communication. His experiments with electromagnetic waves, transmitters, and receivers predated the work of many credited pioneers.
Wireless Energy & Wardenclyffe Tower
Tesla dreamed of transmitting electricity wirelessly across the world. He began constructing the Wardenclyffe Tower, intended to demonstrate global wireless communication and power transmission. Unfortunately, funding issues forced him to abandon the project.
X-rays, Remote Control, Robotics
Tesla performed early experiments with X-rays before their medical applications were fully understood. He also invented the first remote-controlled boat and theorized about automated machines long before the development of modern robotics.
Earthquake Machine & Other Theories
Tesla experimented with mechanical oscillators and resonant frequencies that reportedly caused vibrations strong enough to shake nearby buildings. Although controversial, these experiments demonstrated the potential of resonant energy.
He also speculated on concepts resembling modern radar and guided energy weapons, showcasing his futuristic imagination.
Net Worth
Despite his extraordinary contributions, Nikola Tesla died with almost no money. Due to poor business decisions, failed investments, and uncompleted projects, Tesla struggled financially later in life.
At the time of his death, he was living alone in a New York hotel room with minimal finances. Today, however, his inventions are valued in the billions due to their influence on global technology.
Family
Tesla never married and did not have children. He believed that personal relationships and marriage would interfere with his work and creativity. His family included:
- Father: Milutin Tesla
- Mother: Đuka Mandić
- Several siblings, including an older brother whom Tesla admired deeply
Tesla maintained close ties with some relatives but spent most of his later years in solitude.
Death
Nikola Tesla died on January 7, 1943, in New York City. He passed away quietly in his hotel room at the age of 86. His death marked the end of an era but began a legacy that continues to grow.
Conclusion
Nikola Tesla was a visionary whose ideas powered the future. His contributions to electricity, engineering, wireless communication, and technological advancement are unmatched. Though unrecognized financially during his lifetime, his legacy continues to shape modern innovation and scientific progress.
