Early years

• Tesla went to school in Gospić and Karlovac, Croatia, and studied at the Polytechnic Institute in Graz, Austria and the University of Prague.

• He began his career as an electrical engineer with a telephone company in Budapest in 1881 and next year he joined Continental Edison Company in Paris, where he designed dynamos.

Invention of the induction motor One afternoon, which is ever present in my recollection, I was enjoying a walk with my friend in the city park and reciting poetry. At that age I knew entire books by heart, word for word. One of these was Goethe's Faust. The sun was just setting and reminded me of a glorious passage: The glow retreats, done is the day of toil; It yonder hastes, new fields of life exploring; Ah, that no wing can lift me from the soil Upon its track to follow, follow soaring! As I uttered these inspiring words the idea came like a flash of lightning and in an instant the truth was revealed. I drew with a stick on the sand the diagram shown six years later in my address before the American Institute of Electrical Engineers. My inventions, Nikola Tesla

Alternating motor patent.

Coming to America • Nikola Tesla came to the United States in 1884 with an introduction letter from Charles Batchelor to Thomas Edison: “I know two great men,” wrote Batchelor, “one is you and the other is this young man.” • Tesla worked for Edison on improvement of DC dynamos but soon he founded his own company focusing on AC polyphase system.

Poem, "Fragments of Olympian Gossip"

Nikola Tesla was a prolific inventive genius, poet, and a humanitarian visionary.

While listening on my cosmic phone I caught words from the Olympus blown. A newcomer was shown around; That much I could guess, aided by sound. "There's Archimedes with his lever Still busy on problems as ever. Says: matter and force are transmutable And wrong the laws you thought immutable." "Below, on Earth, they work at full blast And news are coming in thick and fast. The latest tells of a cosmic gun. To be pelted is very poor fun. We are wary with so much at stake, Those beggars are a pest—no mistake." "Too bad, Sir Isaac, they dimmed your renown And turned your great science upside down. Now a long haired crank, Einstein by name, Puts on your high teaching all the blame. Says: matter and force are transmutable And wrong the laws you thought immutable." "I am much too ignorant, my son, For grasping schemes so finely spun. My followers are of stronger mind And I am content to stay behind, Perhaps I failed, but I did my best, These masters of mine may do the rest. Come, Kelvin, I have finished my cup. When is your friend Tesla coming up." "Oh, quoth Kelvin, he is always late, It would be useless to remonstrate." Then silence—shuffle of soft slippered feet— I knock and—the bedlam of the street. Nikola Tesla, Novice
