Top 10 Greatest Inventors in History


How to determine who the greatest inventors in history were is often a passionate and, at times, even a heated debate. Many men can lay claim to having invented or, at very least, perfecting someone else’s obscure invention, making such a listing problematic at best. Fortunately, I don’t maintain any personal favorites, which will hopefully give me the ability to remain a little more objective than some people. I know that some readers whose favorites failed to make the list will consider their oversight a great travesty, but I really do try to do my best.

To pick the top names, I’ve tended towards those who have the greatest number of inventions to their credit—assuming fecundity to be a better gauge of genius—rather than selecting only those inventors who came up with the most significant devices (although there is a degree of overlap between them). That being said, there are a few inventors not on my list who hold over a thousand patents each; they fail to make the cut, however, because almost all of their patents relate to minor variations on a single device (such as a computer processor, for example) or are concentrated in one specific industry rather than over a range of disciplines. Additionally, I do factor in the major impact some inventions had on society but gauge them based upon the degree of technical challenges they represented and the level of technology available to the inventor at the time. And so, without further ado, here are my nominations for the ten greatest inventors of all time.

10. Leonardo Da Vinci

Leonardo Da Vinci

Many will doubtlessly be surprised that one of the greatest minds of the Renaissance has fallen all the way to number ten, but that’s not an indictment of him, but of the times he lived in. The problem was that his ideas were so far ahead of the technology of his age that almost none of his ideas could be realized; as such, technically he didn’t really “invent” anything at all. He was more of a futurist who imagined various innovations rather than a person who possessed the mechanical aptitude to build things with his own hands. Additionally, his interests were so varied that he didn’t get very far in developing any single idea beyond drawing a few sketches or describing his ideas in very general terms. Further, while he came up with futuristic things like gliders and tanks and submarines, he didn’t envision any truly remarkable inventions such as electricity, the telephone, photography, or even sliced bread. A great mind, no doubt, and had he the focus to concentrate on any single idea long enough to bring it into reality, he might well have proven to have been one of the greatest inventors in history. For now, however, I’m afraid the best he can do is finish out the top ten.

9. Edwin Land

Edwin Land

Connecticut physicist and inventor Edwin Land didn’t invent photography, of course, but he invented or perfected almost everything else having to do with it.  While a freshman at Harvard University in 1926, he developed a new kind of polarizer by aligning and embedding crystals in a plastic sheet, which he called Polaroid. Later, joined by other young scientists, he applied the polarizing principle to light filters, optical devices, and motion picture processes and founded the Polaroid Corporation in the process. Holder of no fewer than 535 U.S. Patents, Land is probably best known for developing the first self-developing camera, making it possible to embarrass your friends on the spot rather than having to wait for the film to come back from the drug store before humiliating them.

8. Benjamin Franklin

Benjamin Franklin

Seriously? Ben Franklin? Absolutely! Not many people know that among his many skills (Franklin was a noted polymath, an author and printer, a satirist, a political theorist,a  politician, postmaster, scientist, civic activist, statesman, and diplomat) he was a prodigious inventor. Among his many creations were the lightning rod—a device which saved countless homes and lives from lightning induced fires, the glass armonica (a glass instrument, not to be confused with the metal harmonica), the Franklin stove, bifocal glasses, a carriage odometer and even the flexible urinary catheter (ouch). Franklin never patented any of his inventions, however, believing that innovations should be shared freely with others, which is why he is often overlooked for his creative talents. Writing in his autobiography, he said, “… as we enjoy great advantages from the inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously.” In my book, that makes Ben a top ten candidate.

7. Hero of Alexandria

Hero of Alexandria

If only the man had realized what he had with his invention, the Aeolipile—a primordial steam engine capable of making a metal ball spin—the industrial revolution might have started in 50 CE instead of 1750 CE! Alas, he thought it merely a toy and besides, with slaves around to do all the menial labor, what did you need steam engines for? Of course, Hero—probably one of the finest minds in the Roman Empire—also developed other useful items, including a force pump , the first syringe, a fountain capable of operating off hydrostatic electricity, a windmill operated organ, and even the first coin operated vending machine—all during a pre-industrial age—making him something of an early Thomas Edison. Too bad he didn’t take his inventions a little more seriously or develop them further; if he had, we might live in a very different world today.

6. Jerome “Jerry” Hal Lemelson

Jerome Jerry Hal Lemelson

What, you’ve never heard of Jerome Lemelson? Well, you have now, for he was one of the most prolific inventors in history, with 605 patents to his credit. What did he invent? Things like automated warehouses, industrial robots, cordless telephones, fax machines, videocassette recorders, camcorders and the magnetic tape drive used in Sony’s Walkman tape players. Lemelson also filed patents in the fields of medical instrumentation, cancer detection and treatment, diamond coating technologies, and consumer electronics and television. He was probably best known, however, as a tireless advocate for the rights of independent inventors, which made him a controversial and even much loathed figure by patent attorneys and some of the larger companies whose noses he tweaked, but a champion of the independent inventor’s community.

5. George Westinghouse

George Westinghouse

Though it was Edison that got most of the credit, it’s hard to argue that in many ways Westinghouse’s contributions were almost as great as Edison’s. Certainly it was his electrical system, which used alternating current based (a result of the work of Nikola Tesla, by the way), that ultimately prevailed over Edison’s insistence on direct current and paved the way for the modern power grid. But Westinghouse wasn’t a one-hit wonder; before he bested Edison with his AC power system, he invented the railway air brake, which did much to improve the safety of the American railway system. Like Edison, he also had an experimental streak which induced him play around with a perpetual motion machine. It didn’t quite work, of course (largely due to the fact that such a machine would violate the laws of physics) but you couldn’t blame him for trying. In any case, a prolific inventor and engineer with 361 patents to his credit, Westinghouse easily rounds out the top five candidates.

4. Alexander Graham Bell

Alexander Graham Bell

You don’t often see the inventor of the telephone finish this high on such a list, but when one looks at the accomplishments the man was responsible for during his seventy five years on earth, it seems impossible not to include him in the top five. Though most famous for the telephone (which came about as a result of his early work with the deaf) not many people know he also invented devices that did everything from locate icebergs and  detect minor hearing problems (an audiometer) to finding hidden treasure (he invented the modern metal detector). He even tried his hand at eugenics, built hydrofoils and worked on early airplanes, demonstrating quite a range of interests. And that copy of National Geographic Magazine you’ve been meaning to get around to one of these days? Thank Mister Bell for that as well, for he was one of the founding members of the National Geographic Foundation way back in 1888. Quite a résumé by any standard, if you ask me.

3. Thomas Edison

Thomas Edison

What? The most prolific inventor in modern history, with over a thousand patents to his credit, not number one? The inventor of the light bulb, the phonograph, the motion picture camera and the man who electrified New York City—literally—not top dog? Impossible! Actually, while Edison was a gifted man, many of his better known inventions were developed by others working for him or in collaboration with an entire design team, making him responsible for their development rather than their chief inventor. He also had a nasty tendency to renege on contracts and claim credit for other people’s work, but then nobody is perfect. However, even if he wasn’t personally responsible for everything that came out of his shop at Menlo Park and was at time integrity challenged, he was the master of R & D and oversaw the creation and production of many of the great inventions of the nineteenth century, earning him, if not the number one spot, at least a top five showing.

2. Nikola Tesla

Nikola Tesla

Though largely unknown during his lifetime and a man who died in relative obscurity (and as something of a reclusive mad scientist at that), the brilliant Serb—who is enjoying a resurgence in popularity lately—was probably more responsible for the birth of commercial electricity than any man in history.  While Tesla’s patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor which helped usher in the Second Industrial Revolution, he is probably best known for his work in the field of electromagnetism. He also contributed in varying degrees to the science of robotics, laid the foundation for the development of remote control, radar, and computer science, and even helped in the expansion of ballistics, nuclear physics, and theoretical physics. Some people also believe he developed anti-gravity, teleportation, and even death rays, but that’s a bit more difficult to substantiate. In any case, with 111 patents to his credit, he was genuinely one of the finest and most innovative minds in history whose recognition has been long in coming.

1. Archimedes of Syracuse

Archimedes of Syracuse

How did this ancient Greek scholar come out at number one? Well, first, he did happen to be one of the greatest mathematicians of all time who came close to precisely calculating the value of pi, figured out how to determine the area under the arc of a parabola, and thought up lots of other stuff that brings nightmares to generations of high school math students on a daily basis. Oh, and he also invented a bunch of cool machines, including siege weapons and possibly even a device that may have been capable of setting Roman ships on fire by using mirrors to focus sunlight onto their sails. So how does that make him deserving of the top spot? Because he did all of this more than 2,000 years ago, and without the aid of computers or the benefit of the technologies available to many inventors today.  Additionally, though he may have studied at the libraries at Alexandria (though this is not confirmed) he acquired much of this knowledge the old fashioned way—by thinking it up himself. Considering the times and the obstacles he faced in doing this, he gets my vote for being the greatest inventor of all time.

  1. Impressive ignorance, the Japanese have calculated that 54% of the world’s most important inventions come from Great Britain but there aren’t any British or modern European representatives on your list. I think you might be a little biased or under educated.

  2. JULIE R. Miles on

    These great inventors are they from the United States always. Can we really keep the new inventors out of the United States from other countries. We need inventions this is a world project not just one country. Education in America is challenged with terror on the rise. What will the next President do to make inventors and innovative students be known in America and our country. Will he keep them out?

  3. Thanks for as good a top ten inventor list as I’ve seen anywhere. I actually found a list on some site that didn’t include Tesla. That’s inexcusable ignorance.

  4. …. there are a few missing. a few that invented things on which some of those listed above directly depend.

    Galileo Galilei – invented the telescope, thermometer and more…

    Bartolomeo Cristofori – invented the piano instrument

    Enrico Fermi – invented the first nuclear reactor

    Alessandro Volta – invented the first electric battery

    Jacopo Peri – invented lyric opera

    Guido d’Arezzo – invented musical notes and score sheets

    Eugenio Bersanti – invented combustion engines

    Giovanni Alfonso Borelli – first to develop the principles of bio mechanics

    Bernardo Buontalenti – invented ice-cream

    Ambrogio Calepino – invented/produced the first dictionary

    Salvino degli Armati – invented glasses

    Enrico Forlanini – invented hydrofoil and was pioneer in the invention of zeppelins

    Luigi Lilio – invented the Gregorian Calendar as we use it today

    Luca Pacioli – invented modern accounting

    Evangelista Torricelli – invented the barometer

    Ascanio Sobrero – invented nitroglycerin

    George Washington Carver – invented modern agriculture

    Wright Brothers – invented the first airplane

    Pietro Ferrero – invented Nutella… definitely deserves his spot in the top 10 😉

    (yes, I’m Italian)

  5. Arcanik, you are simply stunned by the greatest invention in more than 300,000 years of humankind on the planet. Or maybe you are scared by its immensity.

  6. With due respect to Nikola Tesla and the rest of the inventors, there is an invention concerning the health of everyone of us – Everything done so far is much too retarded compared to my research and findings regarding the human immune system – my Cancer Killer is by far more powerful than the immune system itself, keeps it intact all the time.
    And so – Everybody can already rest assured – I believe Life is never gonna be the same again – I mean the cure for any diseases on the planet has been invented. And much more than that – any diseases can be prevented 100% – Nature has provided us the unlimited power (like the unlimited free energy of Nikola Tesla) of staying as healthy as Gods, we just gotta activate it by doing my invention – the PCK – The Personal Cancer Killer – the complete prevention and cure (for those now sick) for kids and adults of any diseases – from the common cold to cancer – just an exercise for a minute a day for prevention and for 2 – 3 minutes a day for the cue – any infection is cured for max. 3 days and any cancer – for max. 30 days – no metastases or recurrences of any cancers are at all possible (Cancer Killer is their devastating destroyer). Even bio-terrorism is much too weak against everybody doing the Cancer Killer – any bio-terrorist bugs are killed the moment they touch us.
    The price of the Personal Cancer Killer for the whole world is 340 Billion Bucks, Euro, or GBP (just 48 Bucks for everybody on Earth – not much to possess the greatest invention in human history and to stay as healthy as God). I accept checks of 5 Million Bucks to disclose it personally. Everybody will stay absolutely healthy all the time, all life long – never getting sick of any diseases even for a second.

    • Arcanik Nathaniel Broddisworth on

      I’m sorry, but you aren’t impressing anyone. Actually, I’m not sorry, because anyone who thinks people believe this is not worth my pity.

  7. Where is the man who invented the greatest piece of all?????????…….the printing press!!Johannes Gutenberg!!!! This list is incomplete without him in #1….

  8. Edison wasn’t an inventor. He stole the inventions from other people. PS: Meucci invented the telephone.

  9. on

    I’m very happy with my brand new stethoscope, they sound really clear and loud . I’d recommend them to anyone who works somewhere noisy like in the back of an ambulance.

  10. For everyone complaining about the American inventors, get over it. Almost half on the list are not American. yes there are plenty of inventors through history outside of America. but, look America is the most progressive country in the world so it is only natural major developments in all Fields of industry and technology come from here.

    also, all most all invention are based on some form of idea from some other inventor from even further in the past. but credit should be given to those who made the initial creation of each therefor.

    its a great list and the writer should feel proud. loved that Tesla was higher than Edison. wished that DA Vinci was higher but the writers opinion did make sense to make.

  11. Inventor of the telephone was Antonio Meucci!

    When will correct? When you give the proper honor to the true inventor of the telephone?

  12. This list is kind of ok. Although i think a more fitting name would be, “most popular inventors”. Also, do you call a theory an invention??? I mean, did Einstein invent relativity or did he just find an explanation to a particular act of nature??? …….interesting…….

  13. Parth sakhiya on

    This list is missing the most importat ever invention.. The invention of “ZERO” is the most important..

    • That’s a discovery, not an invention. That’s like saying Europeans invented the New World.

  14. As always, the Americans over-estimate their influence in the world. Believe me, most of the great innovators was born raised and lived outside the US.

  15. I have currently a great invention but need funding for its execution. Heard of this site called but not sure if there are other ways. Thoughts are more than welcome. Thanks in advance. Tina

  16. Edison does not deserve to be called an inventor. Its like saying that executive chef of IBM is the inventor of everything IBM has invented.

  17. Why?
    -Jerome “Jerry” Hal Lemelson – LOL LOL LOL

    -Edwin Land LOL LOL LOL

    -Benjamin Franklin LOL LOL LOL

    -Alexander Graham Bell
    He didn’t inveted the phone. Guglielmo Marconi an italian invertor did it. Don’t know why in USA and Canada teach wrong history.

    -Thomas Edison or better know like “can I fraud your Job?”

    The bulb light in carbon was inveted one year before by Joseph Swan in England.
    Swan’s initial findings from tinkering with carbon filament electric lighting, and his preliminary designs, appeared in an article published by Scientific American. Without a doubt, Edison had access to, and eagerly read this article.

    Swan, felt quite differently, as he watched Edison line his pockets with money made from his invention, and took Edison to Court for patent infringement. The British Courts stood by their patent award for the light bulb to Swan, and Edison lost the suit. The British Courts forced Edison, as part of the settlement, to name Swan a partner in his British electric company. Eventually, Edison managed to acquire all of Swans’ interest in the newly renamed Edison and Swan United Electric Company.

    Did you study at disneyland with mickey mouse?

  18. Every web sit of this kind has its own spin on the greatest inventors.
    Remember “Curly” of the 3 stooges? his idea of the greatest were:
    Robert Fulton
    Alexander Graham Bell
    and Don Ameche.

    • Steve Jobs would be lucky to be in the top 1000 “visionary geniuses”, if individuals were included from all ages, from all corners of the globe, and from all fields of invention like the arts, mathematics, science, philosophy, etc.

    • He didn’t really invent anything, so he wouldn’t be called a inventor. He’s more of a scientist

        • Edison the Businessman on

          Stop twisting words. You know precisely what this list is about. Next thing we know a list of top ten engineers would be interpreted as top ten geniuses in the world.

    • Oh yeah! We should include his contribution to the greatest death machine to ever be invented or seen by men.
      Not a good idea.
      As for his “Theory of Relativity” unproven and actually useless if he is wrong (mainly due to the fact that it means we have been barking up the wrong tree for quite some time) and there is growing concern that he may have been.

      • First off, Jon, #1 on this list was a mathematician as well.

        Yea, he invented stuff, but take away his advances in mathematics and science, and he would have not been on this list.

        Secondly, VexxistheWise, Einstein had absolutely no intention of seeing his discoveries turn into a nuclear weapon. To say that the Theory of Relativity is useless is completely ignorant and naive. Were it not for his knowledge, we would not have made advances toward Nuclear Fusion and new forms of energy, bound to be discovered in the future.

        Also, had Einstein not made this discovery, the US would not have defeated Japan and the USSR would have created the Atomic Bomb before the States, probably changing the modern world drastically.

    • Does this amaze you? It perplexed me (an inventor). Do the research and look. Though I would like to pose that Jesus was one of the greatest with his invention of salvation.

  19. This list as a horrible American bias to it, as do many lists you will find on the internet. Not only that, nearly all the people on the list don’t deserve a mention. Quantity over quality seem’s to be the order of the day on here, if only to add more Americans on to the list.

    • Most authors that write for us are American and the owner (me) is also American so this site will have an American focus. If any writers would like to submit an International article that would be welcomed.

  20. This is funny indeed. Funny because they make no mention of the Black/Africian American inventors… once again pepetuating a fraud of historical facts….

    • The only fraud is that in America Blacks are given false credit for inventing the weakest of inventions. To add insult to injury these “inventions” of halfwits are equated with true genius by placing their names alongside the truly great inventors of history. People like George Washington Carver who “invented” peanut butter or was it the traffic light? Either way there is no way that peanut butter or the traffic light is at the same level of the equations of motion, electricity, radio, airplanes, rockets, lasers, computer chips, steam engines,… the list goes on and on of the truly great inventions made primarily by white men. Other peoples of the earth made significant contributions of course, but none of them were black. None.

      • To say that none of the inventions by Black/African-American inventors are significant contributions is completely ignorant. Without the minds of these so-called halfwits, we may never have gotten the following…

        Air Conditioning
        Cellular Phone
        Clothes Dryer
        Fire Escape Ladder
        Gas Mask
        Hair Brush
        Ironing Board
        Lawn Mower
        Mail Box
        Spark Plug
        Thermostat Control
        Traffic Light

        ^All of the above are very significant to everyday life, so to act as if those inventors don’t deserve any praise is crazy.

        • I disagree. I’m not all about “white power”, but African-American inventors can not be given credit for more significant inventions than, say, Tesla or Da Vinci. But that is not because they are incompetent–there is a historical reason.

          For instance, in one of the most prodigious and innovative countries in the world since 1776, the United States, African-Americans were slaves until 1865, and even after they were freed, blacks did not gain equality under the law until the Civil Rights movement in the 1960’s.

    • Thats because no black inventor has made somthing as great as these people. so fill the chuck out

  21. What about Hedy Lamarr? She co- invented wireless technology. We wouldn’t have Wi Fi if not for early wireless technology.

      • /agreed Tesla is the original inventor of so many things including All types of wireless transmissions.

      • She brought it leaps and bounds closer during the war. And we can than Ada Lovelace for computer programming.

    • Initially Marconi was granted patent for invention of radio but Supreme Court in 1943 thwarted most of these initially Marconi’s patents and awarded them to Tesla. Tesla sued Marconi for infringement in 1915 but unfortunately didn’t live to see his work win after waiting for it half his professional life.
      Biggest bummer is that most books and articles today still name Marconi as father of radio.
      But just google “tesla marconi supreme court” or similar and you’ll find out what’s up.
      For example:
      There was even an incident of someone breaking into Tesla’s office and stealing lots of papers related to his experiments with radio. This happened shortly before Marconi filed for his patents.
      There is so many “firsts” that came from Tesla that most people don’t realize today.
      Many scientists credit Tesla for obtaining firs x-ray pictures. Although Tesla gave a full credit to Roentgen, the latter actually wrote a letter to Tesla expressing gratitude for Tesla’s work in the field.
      Check this out for more info about that:
      And so much more that we need to be grateful to this man.
      But least of all he was looking for public gratification.
      All he wanted was to give light to people.

    • Very much agreed…..the things he could have gave the world if it wasn’t for Evil Edison and his Pinkerton ways.

  22. You missed it with leaving out Eli Whitney. Not only did he invent the Cotton Gin, which made modern Cloth possible, but he also invented the “American Manufacturing method.” This is the basis of all modern production. It includes interchangeable parts in products, standardized tools and methods. He was not only responsible for the invention that insured the continued survival of Slavery (which was on its way out before the gin), but he invented the manufacturing method that insured that the North would win the war to get rid of it.

  23. I have seen that there was an inventor with the named of Murray/Murphy whom had the secone most patents behind Edison. Does the name ring a bell? Can;t remember his first name.
    I woudl say Da Vinci is number 1 due to his idea although he was not able to use them. Just thinking of such ideas is hundreds of years ahead of time.

  24. There is controversy over whether the “true” inventor of the first electronic telephonic device was Alexander Graham Bell or Elisha Gray. Both Alexander Graham Bell and Elisha Gray developed electronic telephonic devices but Bell was awared the patent. Bell was accused of stealing many of Gray’s ideas. This is still somewhat controversial although Bell got the credit and the patent. This is just for those interested in these kinds of things.

  25. Franklin was born in Boston, so it’s no surprise the Massachusetts legislature voted him the state inventor, one of a long line of state symbols.

  26. Edison didn’t invent the lightbulb, it was originally invented by Humphrey Davy, Edision was just one of many people who improved on the design, but W.D Coolidge is the one more recently who improved on the design with using tungsten filament

      • Totally agree. Edison is highly overrated, mostly because he unlike Tesla pandered to the press. Not only did he do everything in his megalomaniacal power to thwart Westinghouse and Tesla .. he was also the INVENTOR of:
        – the non disclosure act
        – smear campaign
        – plagiarizer of the actual source of the light bulb patent by Joseph Swan including his art
        work on the patent.

        Lets be very clear here, had Edison have won the war of the currents electricity would have been the inefficient plaything of the rich, and delayed modern power distribution by at least
        one generation. Think of the lost advances ..

        Edison was NOT the greatest inventor of his time, Tesla was.

        • Thank You! Nikola Tesla deserves more credit, and Edison is truly overrated… Why don’t teachers talk about Tesla?

        • After Albert Einstein received hes nobel prize, a reporter asked hes how it felt to be the smartest man in the world.

          Einstein answered “i wouldnt know, you should ask Nikola Tesla”

          I think that says it all.

          The info isent really correct here, tesla was very well known when he was alive. But thanks to all the people that used him and stole hes inventions, they stol hes very well deserved place in historie.

  27. Would you believe Franklin is the state inventor of Massachusetts? Yep, he’s one of the Bay State’s many symbols. No surprise, Ben was born in Boston.
