Inventions

10 questions · Technology

Few inventions come out of nowhere and some owe everything to chance. When Alexander Fleming returned from a holiday in 1928, a mould had killed the bacteria in a Petri dish he had left out by mistake: penicillin, the first antibiotic, went on to save countless lives. Other breakthroughs were sheer hard work. Thomas Edison built not the first but the first practical light bulb, together with a whole electricity grid, and held over 1000 patents: genius, he said, was one percent inspiration and 99 percent perspiration. Around 1450 Johannes Gutenberg made books fast and cheap to reproduce with movable metal type, hugely accelerating education, the Reformation and science. The improved steam engine of James Watt, after whom the unit of power is named, became the engine of the Industrial Revolution. In 1876 Alexander Graham Bell received the patent for the telephone, and in 1886 Carl Benz built his Motorwagen, although it was his wife Bertha who made it famous with a secret long-distance drive of over 100 kilometres. The sky was conquered in 1903 by two bicycle makers from Ohio: the Wright brothers achieved the first controlled powered flight, lasting just twelve seconds at first. The Swedish chemist Alfred Nobel tamed nitroglycerin as dynamite and used his fortune to endow the Nobel Prizes. Albert Einstein changed our picture of space and time with the theory of relativity, and around 1989 Tim Berners-Lee created the World Wide Web at CERN and deliberately gave it away, unpatented.

All questions with answers

Who invented the World Wide Web?

Show answer

Tim Berners-Lee

The British computer scientist invented the World Wide Web around 1989 at the CERN research centre, to link documents over the internet. He created HTTP, HTML and the first website.

💡 Did you know? He deliberately made his invention free and unpatented.

Who introduced movable-type printing in Europe?

Show answer

Johannes Gutenberg

Around 1450 Gutenberg's printing with movable metal type made books fast and cheap to reproduce for the first time. This hugely accelerated education, the Reformation and science.

💡 Did you know? His most famous work is the 'Gutenberg Bible'.

Who is regarded as the inventor of the practical light bulb?

Show answer

Thomas Edison

Edison developed not the first, but the first practical, long-lasting light bulb: plus a whole electricity grid. He held over 1000 patents.

💡 Did you know? His motto: 'Genius is one percent inspiration and 99 percent perspiration.'

Who patented the telephone?

Show answer

Alexander Graham Bell

Bell received the patent for the telephone in 1876, introducing long-distance communication. He also worked all his life on helping the deaf.

💡 Did you know? The first words on the telephone are said to have been: 'Mr. Watson, come here, I want to see you.'

Who built the first automobile with an internal-combustion engine in 1886?

Show answer

Carl Benz

In 1886 Benz built the 'Motorwagen', the first practical automobile with a petrol engine. His company later became Mercedes-Benz.

💡 Did you know? The first long drive was made secretly by his wife Bertha Benz: over 100 km, to make the car known.

Whose improved steam engine powered the Industrial Revolution?

Show answer

James Watt

Watt decisively improved the steam engine, making it efficient enough for factories and mines. It thus became the engine of the Industrial Revolution.

💡 Did you know? The unit of power, the 'watt', is named after him.

Who discovered penicillin in 1928?

Show answer

Alexander Fleming

Fleming discovered the first antibiotic, which has saved countless lives. Bacteria in a Petri dish had been killed by a mould.

💡 Did you know? The discovery was an accident: he had left the dish out by mistake before a holiday.

Who developed the theory of relativity?

Show answer

Albert Einstein

Einstein revolutionised the understanding of space, time and gravity. His formula E=mc² shows the equivalence of mass and energy.

💡 Did you know? He received the Nobel Prize not for relativity but for the photoelectric effect.

Which Ohio siblings made the first controlled powered flight in 1903?

Show answer

Wright brothers

The US brothers Orville and Wilbur Wright achieved the first controlled powered flight in 1903. Their 'Flyer' stayed aloft for just twelve seconds at first.

💡 Did you know? They had run a bicycle workshop: which helped them build light, sturdy structures.

Who invented dynamite and endowed the prizes awarded in Stockholm and Oslo?

Show answer

Alfred Nobel

The Swedish chemist made the dangerous explosive nitroglycerin manageable with dynamite. With his fortune he endowed the Nobel Prizes.

💡 Did you know? A newspaper error once called him a 'merchant of death' in his lifetime: said to have prompted the endowment.
