Inventions & Inventors Quiz — 7 Free Questions

Question 1

Who patented in 1903 a lever inside a vehicle that let the driver sweep a rubber blade across the outside of the glass to clear rain and snow, after watching a tram driver in New York struggle along with his front window flapping open in a storm?

Question 2

Which DuPont chemist led the team that in 1935 created the first fully synthetic fibre, a strong silky polymer drawn into fine threads, shown to the public in women's stockings in 1939 and then turned over to parachutes and rope for the war?

Question 3

Who ran the first steam locomotive to haul a load along rails, in 1804, pulling ten tons of iron and seventy men nearly ten miles along a Welsh tramway to settle a wager, using high-pressure steam that his cautious contemporaries thought reckless?

Question 4

Who brought the first commercially practical incandescent lamp to market in 1879, after his laboratory had tried thousands of filament materials and settled on carbonised bamboo that could glow for well over a thousand hours, even though a chemist in the north of England had shown a very similar lamp a year earlier?

Question 5

Who invented hook-and-loop tape in the 1940s after studying under a lens the burrs that clung to his dog and his trousers on an Alpine walk, and seeing that they gripped with thousands of tiny hooks catching loops of fur and thread?

Question 6

Which English chemist invented the friction match in 1826 after a blob of dried chemicals on a stirring stick burst into flame when he scraped it on the stone floor to clean it, yet never patented it and sold the splints loose from a tin?

Question 7

Which Scottish instrument-maker patented a 'separate condenser' in 1769 that roughly doubled the fuel efficiency of the mine-pumping engine then in common use, a gain that helped drive the Industrial Revolution and later gave his name to a unit of power?

About Inventions & Inventors

An invention is the moment a want becomes a working thing. Somebody is annoyed that letters take weeks, that light means a candle, that surgery means being held down, and after a long stretch of tinkering, borrowing and failing, an object exists that did not exist before, and daily life quietly reorganises itself around it. The popular picture of a lone genius and a flash of insight is mostly a myth. Real inventions tend to arrive from several directions at once, lean on a stack of earlier work, and only look inevitable in hindsight.

This quiz runs across the whole span of that effort: communication, from the telegraph and telephone to the transistor and the integrated circuit; power and transport, from the steam engine and the electric battery to the bicycle and the pneumatic tyre; medicine, from anaesthesia to antiseptics; and materials, from vulcanised rubber to the first fully synthetic plastic. It also steps outside the usual Western list to take in paper and the decimal system with its number zero, two inventions without which almost none of the rest could have been written down or calculated.

Two traps come with the territory, and the answers try to handle both honestly. The first is disputed priority. The telephone, the light bulb, the integrated circuit, the sewing machine and the air-filled tyre each had two or more people arriving at nearly the same place at nearly the same time, and the name history keeps is often the one who patented, published or promoted first, not the one who was strictly earliest. Where a claim is genuinely contested, the explanation says so and names the rival. The second trap is the lone-inventor myth: many of these breakthroughs were the work of teams, backers and assistants whose names were left off the patent, and the answers put some of them back.

Each question describes an invention and the story around it without naming the person, country or thing responsible, and gives you four choices. The explanation then fills in the date, how the thing actually worked, who came a close second, what made it finally practical, and what it changed. Where a freely licensed photograph exists that shows the object or the setting but not the inventor's face, it is shown with the question; where the object itself would give the game away, the question is left as text.

The reason an inventions quiz sticks in the memory is that every answer is something you can hold in your hand or picture on a bench: a stack of metal discs, a bamboo thread glowing in a glass bulb, a ball rolling in the tip of a pen. Learn who built the first of each, and who nearly beat them to it, and you are also learning the shape of how a whole field moved from impossible to ordinary. The wording is kept plain, and every claim has been checked against reliable sources.
