The greatest geek who ever lived had more than just science on the brain. While he was alive, Nikola Tesla’s advancements were frequently and famously attributed to others. But history has shown us the magnitude of his work, a sentiment best expressed by Fiorello LaGuardia’s eulogy: “Tesla is not really dead. Only his poor wasted body has been stilled. The real, the important part of Tesla lives in his achievement which is great, almost beyond calculation, an integral part of our civilization, of our daily lives.” Here are 13 electric quotes from the legendary scientist/engineer/inventor.

1. ON GENDER EQUALITY

“... The female mind has demonstrated a capacity for all the mental acquirements and achievements of men, and as generations ensue that capacity will be expanded; the average woman will be as well educated as the average man, and then better educated, for the dormant faculties of her brain will be stimulated to an activity that will be all the more intense and powerful because of centuries of repose. Woman will ignore precedent and startle civilization with their progress.”

—From a 1926 interview by John B. Kennedy, “When Woman Is Boss"

2. ON BEING AMERICAN

“... The papers, which 30 years ago conferred upon me the honor of American citizenship, are always kept in a safe, while my orders, diplomas, degrees, gold medals and other distinctions are packed away in old trunks.”

—From “My Inventions V – The Magnifying Transmitter," 1919

3. ON BEING SERBIAN

“There is something within me that might be illusion as it is often case with young delighted people, but if I would be fortunate to achieve some of my ideals, it would be on the behalf of the whole of humanity. If those hopes would become fulfilled, the most exciting thought would be that it is a deed of a Serb.”

—From an address at the Belgrade train station, 1892

4. ON UNIVERSAL PEACE

"We begin to think cosmically. Our sympathetic feelers reach out into the dim distance. The bacteria of the 'Weltschmerz' are upon us. So far, however, universal harmony has been attained only in a single sphere of international relationship. That is the postal service. Its mechanism is working satisfactorily, but—how remote are we still from that scrupulous respect of the sanctity of the mail bag!"

—From “The Transmission of Electrical Energy Without Wires as a Means for Furthering Peace,” 1905

5. ON HIS LEGACY

“What the result of these investigations will be the future will tell; but whatever they may be, and to whatever this principle may lead, I shall be sufficiently recompensed if later it will be admitted that I have contributed a share, however small, to the advancement of science.”

—From “The Tesla Alternate Current Motor,” 1888

6. ON PATIENCE AND PLANNING

“That is the trouble with many inventors; they lack patience. They lack the willingness to work a thing out slowly and clearly and sharply in their mind, so that they can actually 'feel it work.' They want to try their first idea right off; and the result is they use up lots of money and lots of good material, only to find eventually that they are working in the wrong direction. We all make mistakes, and it is better to make them before we begin.”

—From “Tesla, Man and Inventor,” 1895

7. ON ALIENS

“Most certainly, some planets are not inhabited, but others are, and among these there must exist life under all conditions and phases of development.”

—From “How to Signal to Mars,” 1910

8. ON INDIVIDUALISM AND MANKIND

"When we speak of man, we have a conception of humanity as a whole, and before applying scientific methods to the investigation of his movement, we must accept this as a physical fact. But can anyone doubt to-day that all the millions of individuals and all the innumerable types and characters constitute an entity, a unit? Though free to think and act, we are held together, like the stars in the firmament, with ties inseparable. These ties cannot be seen, but we can feel them. I cut myself in the finger, and it pains me: this finger is a part of me. I see a friend hurt, and it hurts me, too: my friend and I are one. And now I see stricken down an enemy, a lump of matter which, of all the lumps of matter in the universe, I care least for, and it still grieves me. Does this not prove that each of us is only part of a whole?"

—From “The Problem of Increasing Human Energy,” 1900

9. ON WASTEFULNESS

“We build but to tear down. Most of our work and resource is squandered. Our onward march is marked by devastation. Everywhere there is an appalling loss of time, effort and life. A cheerless view, but true.”

—From “What Science May Achieve this Year,” 1910

10. ON CLEANLINESS

“Everyone should consider his body as a priceless gift from one whom he loves above all, a marvelous work of art, of indescribable beauty, and mystery beyond human conception, and so delicate that a word, a breath, a look, nay, a thought may injure it. Uncleanliness, which breeds disease and death, is not only a self-destructive but highly immoral habit.”

—From “The Problem of Increasing Human Energy," 1900

11. ON THE TECHNOLOGY OF THE FUTURE

"It will soon be possible to transmit wireless messages around the world so simply that any individual can carry and operate his own apparatus."

From Popular Mechanics via the New York Times, October 1909

12. ON OTHERS TAKING CREDIT FOR HIS INVENTIONS

"Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I really worked, is mine."

—As quoted in Tesla: Man Out of Time, by Margaret Cheney, 2001

13. ON THE MYSTERIES OF LIFE

“Life is and will ever remain an equation incapable of solution, but it contains certain known factors.”

—From “A Machine to End War,” 1935 [PDF]
