18th Century Inventors & Discoverers

George Stephenson was a British mechanical and civil engineer. Stephenson is credited with pioneering rail transport which is widely regarded as one of the most prominent inventions of the 19th century. Regarded as the Father of Railways, George Stephenson is also credited with developing the standard rail gauge which is used by several railways around the world.

Nicéphore Niépce revolutionized science by inventing heliography and made the first permanent photographic image. He had initially been part of Napoleon’s army but had to quit due to his failing health. The Niépce Prize is awarded to a photographer every year in France, in his honor.

Best remembered for his contribution to the chemistry of gases, Joseph Priestley was an English scientist, clergyman, political theorist and educator, who has been credited with discovering oxygen independently, publishing his findings before Carl Wilhelm could. A prolific writer, he has authored 150 works on various subjects including electricity. He also contributed immensely to the advancement of political and religious thoughts.

Best remembered for his invention of the Davy lamp, a safety lamp for miners, Humphry Davy initially aspired to be a doctor but later deviated to chemistry. The Copley Medal winner had co-founded the Zoological Society of London. He also excelled in writing poetry and loved fishing.

Initially a wig-maker, Richard Arkwright later grew an interest in the spinning mechanism, building the Arkwright’s water frame, which used water power to produce cotton yarn. He soon became a name to reckon with in the textile industry, with many mills to his name. He was knighted for his feats.

Richard Trevithick was a British mining engineer and inventor. A pioneer of rail transport and steam-powered vehicles, Trevithick is credited with developing the first working railway steam locomotive and the first high-pressure steam engine. He was a highly respected figure in the fields of engineering and mining during the peak of his career.

Benjamin Franklin is considered one of the founding fathers of the United States as he was a signer of both the Declaration of Independence and the Constitution. He was a writer, politician, scientist, inventor, civic activist, an accomplished diplomat and much more. He is a key figure in the history of physics for his discoveries and theories regarding electricity.

American astronomer, inventor, mathematician, clockmaker and surveyor David Rittenhouse, who served as first director of the United States Mint and remained a  member of the American Philosophical Society, made several significant breakthroughs for the US. His achievements include discovering the atmosphere of Venus and observing its transit, becoming the first American to sight Uranus, and completing an advanced orrery.

Known for his pathbreaking Gay-Lussac's Law, French chemist-physicist Joseph Louis Gay-Lussac was also the first, along with his colleague Alexander von Humboldt, to discover that water is composed of one part of oxygen and two parts of hydrogen. His name is one of the 72 that adorn the Eiffel Tower.

British engineer and inventor George Cayley was a pioneer of aeronautics and aviation. He designed the world’s first glider that could successfully carry a human being. He was also a prominent Whig and had contributed to the formation of what is now known as the University of Westminster.

The son of renowned astronomer William Herschel, John Herschel was educated at Eton and Cambridge and grew up to be a polymath. Apart from contributing to the field of photography, he was known for cataloguing and naming stars and satellites. He briefly also served as the Master of the Royal Mint.

Augustin-Jean Fresne, best remembered for his pioneering research on the wave theory of light, was a sickly child and was mostly homeschooled in his early days. The French physicist was a civil engineer, too. Unfortunately, most of his scientific work failed to receive public attention during his lifetime.

Best known for developing the Charles’s law, which explains the expansion of gases when heated, Jacques Charles was a prominent French physicist. He was the first to ascend in a hydrogen-filled gas balloon, thus pioneering hot-air balloon flight. The Académie des Sciences member later became a professor of physics.

David Brewster was a British scientist, inventor, and author. He conducted many experiments in physical optics, especially concerned with the study of the polarization of light. Fellow scientist William Whewell dubbed him the "father of modern experimental optics." He was also a pioneer in photography and invented an improved stereoscope. He wrote numerous works of popular science as well. 

Scottish engineer John Loudon McAdam introduced the world to the macadam road surface, which was more economical and effective than all previous road-construction methods. He suggested that roads should be constructed at an elevated level for better drainage. He also became Britain’s Surveyor-General of Metropolitan Roads.

Jacques de Vaucanson was a French artist and inventor. He is credited with creating impressive and innovative automata. De Vaucanson was also the first inventor to design an automatic loom. His ideas for the automation of the weaving process were later perfected by Joseph Marie Jacquard, who created the Jacquard machine.    

William Sturgeon was an English physicist and inventor. He invented the first practical English electric motor and made the first electromagnets. A self-taught genius, he became a lecturer at the East India Company's Military Seminary at Addiscombe, Surrey. Along with John Peter Gassiot and Charles Vincent Walker, he was instrumental in founding the London Electrical Society in 1837.
