Nikola Tesla was an inventor and a mechanical and electrical engineer. He is best known for his revolutionary developments in the field of electricity and magnetism in the late 19th and early 20th centuries. An astonishing autobiography, this book touches on his life and career, his first inventions and discoveries. Born an ethnic Serb in the village of Smiljan, Vojna Krajina, in the territory of today's Croatia, he was a subject of the Austrian Empire by birth and later became an American citizen. After the invention of wireless communication (radio) in 1894, he was widely known as one of the greatest electrical engineers who worked in America. Tesla was later ostracized and regarded as a mad scientist. Never having put much focus on his finances, Tesla died impoverished at the age of 86.
