Not all inventors are remembered, but there are those it’s impossible to overlook. We’re talking about men and women who haven’t just accepted things as they are, but applied brainpower, sweat and tears to finding new ways of doing things. Make no mistake, the inventors listed below, whether their names are instantly recognisable or unfamiliar, are all figures without whom our world would be very different.

Chronologically, their lives take us from sun-kissed Syracuse in Sardinia three centuries before Christ was born to the world’s largest physics laboratory at the dawn of the 21st century. Still, were they all to meet, you would guess they would have, at the very least, a keen sense of curiosity in common. And if this list seems noticeably male, well, imagine how different it might look if women had been given the same opportunities as men down the centuries.

14 famous inventors from across history

Archimedes

(c287-212BC)

Some inventions become so closely associated with their creators that they bear their names. The Archimedes screw is one such example. Traditionally attributed to the third-century BC mathematician, its spiral blade, fitted inside a tube, lifts water with each rotation. Long used for irrigation and drainage, it’s still employed today within wastewater treatment and even power generation.

Archimedes also carried out foundational work on the principle of the lever and is famously reputed to have declared: “Give me a place to stand, and I will move the Earth.” If that weren’t enough, he calculated upper and lower limits for the value of pi, made powerful war machines to protect his home city of Syracuse when it was besieged by the Romans, and formulated the law of buoyancy, also known as Archimedes’ principle.

Most famously, he is said to have cried “Eureka!” when he saw how the water level rose when he stepped in his bath, paradoxically a moment of displacement activity and, because he realised how this could help measure the volume of irregular objects, utter clarity.

Cai Lun

(c50/62–121AD)

Widely credited with making significant improvements to the paper-making process in Han China, Cai Lun, a eunuch court official, changed the world via the use of some unpromising materials – tree bark, hemp waste, old rags and discarded fishing nets. In combining these to make pulp, which he spread in thin layers and allowed to dry into sheets, he also helped make the widespread manufacture of paper a practical proposition.

He reported his method to the Chinese emperor in 105AD. Archaeological finds have revealed paper fragments dating from centuries earlier, but the innovations associated with Cai Lun helped change the way paper, which soon became crucial in both communications and record-keeping, was made and used.

Zhang Heng

(78-139AD)

Nowadays, the design of seismometers, used to detect earthquakes, leans towards the functional. However, the first known seismoscope, invented by Zhang Heng in 132 AD, was an altogether more elaborate device. According to historical accounts, his bronze vessel featured eight dragon heads and eight toads. When an earthquake occurred, an internal mechanism would release a ball from a dragon’s mouth into that of a toad, indicating the direction of the tremor. Its precise internal workings remain uncertain.

The inventor, working during the Eastern Han dynasty, also studied the stars and constellations, and explained how the Earth’s shadow caused lunar eclipses.

Ismail al-Jazari

We have Ismail al-Jazari to thank for a number of inventions and developments from the medieval Islamic world. Much of his work involved water, including pumps and water-raising machines used in agriculture, as well as automated devices for handwashing.

Al-Jazari also designed the elephant clock, an elaborate, water-powered clock that used a system of falling balls and moving figures to mark the passage of time. His work in mechanics included an early crank-and-connecting-rod mechanism, used to convert rotary motion into the back-and-forth movement needed to operate a pump.

Johannes Gutenberg

(c1393/1406–1468)

Movable type had already been used in East Asia, but it was Johannes Gutenberg who brought together metal type, suitable ink and a press in a commercially successful process. Using an alloy of lead, tin and antimony, he was able to create small metal letters that could be moved and reused to print different pages.

In conjunction with oil-based ink, the German craftsman’s system made the large-scale production of books much more practical. The Gutenberg Bible, completed around 1455, was the most famous product of his endeavours. The spread of printing helped drive an information revolution, circulating the ideas of the Renaissance and, later, the Reformation.

Leonardo da Vinci

Arguably the best-known name on this list, Leonardo da Vinci was a prolific designer of machines. The Italian produced pioneering designs for flight, including the ornithopter and the aerial screw. These remained unproven designs, but reveal his fascination with a challenge that would occupy inventors for centuries.

As well as painting the Mona Lisa, Leonardo designed various mechanical devices, including a self-propelled cart. His military designs included an armoured vehicle, a giant crossbow and a 33-barrelled organ gun, intended to allow one set of barrels to fire while others cooled or were reloaded.

James Watt

(1736–1819)

While Thomas Newcomen (1664–1729) developed an early practical steam engine, it was engineer, chemist and instrument maker James Watt whose work ensured steam engines powered the Industrial Revolution.

Between 1765 and 1784, Watt was behind a series of design innovations that built on Newcomen’s work. These included the introduction of a separate condenser to keep the engine cylinder hot while cutting fuel waste; the use of sun-and-planet gearing to allow an engine to turn a shaft; the double-acting engine, in which steam acted on both sides of the piston to generate power; and the development of a parallel motion linkage, which helped guide the piston rod along a straight line.

Alessandro Volta

(1745-1827)

Constructed from alternating copper and zinc discs separated by brine-soaked cardboard or cloth, Alessandro Volta’s voltaic pile was the first electric battery capable of providing a sustained current. Announced in 1800, the device generated a current through chemical reactions when a wire connected the top and bottom of the stack.

Volta also discovered methane gas in 1776, and took important steps towards understanding electrical potential and electromotive force. By demonstrating that an electric current could be generated without living tissue, his work challenged the idea of “animal electricity” put forward by Luigi Galvani (1737–98). The unit of electrical potential, the volt, was later named in Volta’s honour.

Ada Lovelace

(1815–52)

The only woman on this list, Ada Lovelace, the only legitimate daughter of Lord Byron (1788–1824), was a mathematician and writer often credited as the world’s first computer programmer. In 1833, she first met Charles Babbage (1791–1871), the designer of the difference engine, a revolutionary mechanical calculator. Over several months between 1842 and 1843, Lovelace translated an article about Babbage’s proposal for an analytical engine – a mechanical, general-purpose computer – that had been written by the engineer and future Italian prime minister Luigi Menabrea (1809–96). Her notes for the piece were extensive, and one included an algorithm for calculating Bernoulli numbers (important in calculus).

More than 100 years before the development of modern electronic computers, Lovelace recognised that Babbage’s machine might have possibilities beyond arithmetic, including manipulating symbols and composing music.

Thomas Edison

(1847–1931)

In total, Thomas Edison had 1,093 US patents to his name, covering major innovations in lighting, sound recording and electrical power. His most famous achievement was the development, with his research team, of a practical incandescent light bulb in 1879. He was not the first to invent an incandescent bulb, but his work helped make electric lighting commercially viable.

However, Edison is said to have regarded the phonograph – the first machine capable of recording and playing back sounds – as his favourite invention. He also developed an improved carbon telephone transmitter, while his laboratory produced the kinetoscope, a device allowing one person to watch a short film. Edison and his team’s work was thus pivotal to the evolution of cinema.

Edison also had an unexpected influence on body art. His electric pen, patented in 1876 to help duplicate documents, inspired an early electric tattooing machine.

Alexander Graham Bell

(1847–1922)

Alexander Graham Bell’s work was closely intertwined with that of his close contemporary, Edison. Bell secured his landmark telephone patent in 1876, while Edison subsequently developed a transmitter that improved the technology.

Bell also worked in sound recording. Research at his Volta Laboratory, with his cousin Chichester Bell (1848–1924) and the inventor Charles Sumner Tainter (1854–1940), led to the graphophone – a device that used wax recording surfaces rather than the tinfoil employed in Edison’s early phonograph.

Alongside his more prominent work, Bell developed devices to measure hearing and an early metal detector, which he used in an unsuccessful attempt to locate a bullet lodged in the dying US president James A. Garfield (1831–81).

Nikola Tesla

(1856–1943)

Today, the name Tesla is widely associated with the electric car company named in his honour. Nikola Tesla himself played a major role in developing alternating current (AC) power systems, including the induction motor and polyphase technologies he patented in 1888. His work helped make AC practical for distributing electricity and powering machinery, although alternating current itself predated his inventions.

Tesla also invented the Tesla coil, a high-voltage transformer circuit used in experiments with electricity and wireless transmission. He pioneered remote-control technology, demonstrating a radio-controlled boat in 1898, and experimented with electric lighting.

Tesla’s work also became central to the “war of the currents”, the late-19th-century contest over how to distribute electrical power. Working with engineer George Westinghouse (1846–1914), he helped advance AC systems in competition with the direct-current technology championed by Thomas Edison.

Orville & Wilbur Wright

The Wright brothers were self-taught mechanics and bicycle shop owners from Ohio who turned their attention to aviation and ended up changing the world. In 1903, they achieved the first sustained, controlled flight of a powered, heavier-than-air aircraft. Known as the Wright Flyer, their machine featured a wooden frame, carved propellers, fabric-covered wings and a lightweight petrol engine.

It was Orville who piloted that first flight, on 17 December near Kitty Hawk in North Carolina, lasting 12 seconds and covering 120 feet. The siblings overcame one of the problems that had challenged aviation inventors for generations by developing a three-axis control system. Combining wing warping with an elevator and a rudder allowed pilots to steer and balance the aircraft in flight.

Sir Tim Berners-Lee

(b1955)

The ability to read this list on a website can be traced back to the work of Sir Tim Berners-Lee, who invented the World Wide Web in 1989 while working at CERN. An earlier project, a database program called ENQUIRE, had explored hypertext concepts to connect pieces of information through electronic links.

His breakthrough came with the development of HTML, HTTP and URLs, alongside the software for the world’s first web server and browser, completed by the end of 1990. Berners-Lee wanted the web to be universally accessible. In 1993, CERN placed its web software in the public domain – a decision that helped transform how the world shares information.
