40 Greatest Inventors In World History And What They Invented

By Joe Burgett - March 25, 2020

7. George Westinghouse

Most Famous For Inventing: Railway Air Brake, Alternating Current Distribution System

George Westinghouse was a brilliant man and one of the world’s greatest inventors during his time. Working as an engineer, he invented the railway air brake, something that helped all trains stop. In fact, this essential fail-safe system is still in place today in both trains and subways. This made him a wealthy man, allowing him to get into the electrical game with Nikola Tesla.

This allowed Westinghouse to develop the electrical distribution system for alternating current. It’s actually in use today every time you plug something in at home. His AC electrical concept was far better than the direct current because it could flow both ways while DC could only flow one way. George’s AC system is what we all use to power things today.

6. Robert Fulton

Most Famous For Inventing: First Commercially Successful Steamboat, The Submarine

When you talk about the world’s greatest inventors, the list could not be complete without Robert Fulton. While Fulton did not invent the steamboat, but he did invent the first commercially successful version that could travel long distances.

He was even commissioned by former French General & Emperor Napolean Bonaparte to build what would become the first-ever submarine. He called it the Nautilus and it actually worked very well. On top of this, Fulton invented the first successful naval torpedoes for the British Royal Navy. The man changed travel and how militaries operated forever.

5. Thomas Edison

Most Famous For Inventing: Phonograph, Movie Camera, Direct Current, The Light Bulb

Thomas Edison is not only one of the greatest inventors in history but possibly the greatest ever. It is not hard to see why. Edison held over 1,000 patents for his inventions during his life. This includes the Phonograph, which was the first sound recorder and player. He also invented the first motion picture camera and opened the first film studio.

Edison used his knowledge of sound to make the first automatic telegraph. He then improved on Alexander Graham Bell’s telephone design by inventing a better transmitter, the “Carbon Telephone Transmitter.” Edison also improved the automobile with his invention of the Alkaline Storage Battery. Thomas is also responsible for inventing direct electrical currents for commercial energy use. This helped in his invention of the light bulb, likely his most notable invention.

4. Leonardo Da Vinci

Most Famous For Inventing: Helicopter, Parachute, Diving Suit, Machine Gun, Tank

People know Leonardo Da Vinci most for his paintings usually. He painted masterpieces like the Mona Lisa & The Last Supper. Both of these are some of the best artworks in world history. However, Da Vinci was a genius who invented several different yet important things. This includes The Parachute, The Tank, The Machine Gun, Diving Suits, and multiple flying machines.

Da Vinci’s most notable flying machine, the Ariel Screw, is the basis for how helicopters work today. He also invented a robot but passed before building it. We know of this due to the discovery of his notebooks with multiple drawings of inventions he had planned. Leonardo also invented the Revolving Bridge, those bridges that open up to let boats go underneath them when the ship is too large.

3. Hero of Alexandria

Most Famous For Inventing: The Syringe, Force Pump, First Wind-Powered & Automatically Powered Machines

Hero of Alexandria lived during the Greco-Roman era in Alexandria, Egypt. He is notably a skilled machine maker and mathematician. Hero invented the force pump, the hose firemen use today. The first Syringe was his making, which holds and delivers liquid or air of various types. He is also responsible for the first vending machine!

Hero also invented the first wind-powered machine & the first truly automatic machine. The latter was a fountain that worked on hydro-static energy, now called Heron’s Fountain. He also invented a programmable cart that was powered by a falling weight, which consisted of strings wrapped around a drive axle. The man was even was able to uncover the principle for the shortest path of light. This later became the basis for Alhacen’s principle of reflection & refraction.

2. Nikola Tesla

Most Famous For Inventing: Alternating Current Tech, Hydro-Electric Energy, Tesla Coil, The Remote Control

Many consider Nikola Tesla to be one of the greatest inventors in history due to inventing multiple things we use in some form today. While working for Thomas Edison, Tesla came up with alternating current technology. Deciding to leave Edison behind, he met with George Westinghouse who financed Tesla’s AC ideas, allowing both men to eventually win the “Current War.”

Yet Tesla knew other ways energy could be utilized. This was when he came up with Hydro-Electric Energy, which he used to power the city of Buffalo, NY at one point. Many feel his Telsa Coil is his most notable invention, however. It laid the foundation for wireless technology, with the radio world still using a form of it today. Oh yeah, and he invented the remote control & discovered Violet Rays.

1. Archimedes of Syracuse

Most Famous For Inventing: Geometry Of Shapes, Pi, Compound Pullies, Archimedes Screw

Any list of the world’s greatest inventors is not complete without the inclusion of the infamous Archimedes of Syracuse. He invented geometric algorithms, laying the foundation for Calculus among other math forms to work. This includes being the first to use theorems like the area of a circle, surface area, volume, sphere, and the area under a parabola.

He used this to come up with “Pi” too. These theorems allowed him to discover and found statics and hydrostatics, including the entire concept of how levers operated. Later on, people credited him for the invention of compound pullies and the screw pump. The Principle of Buoyancy is credited to him, referred to as the Archimedes Principle. He is also known for, of course, the Archimedes Screw.
