Haarlem
Teylers Museum and its electrostatic machine.
Route by public transport ↗From the telescope to Bluetooth.
A small country with lots of water and little space has to be clever. The Dutch were the first to look at the stars through a telescope, saw bacteria under a microscope, built a submarine, invented the stock market, the cassette and the CD, and helped create Bluetooth and Wi-Fi.
Some inventions came from workshops in Middelburg and Delft, others from the laboratories of Leiden, the Philips factories in Eindhoven or an office in Amsterdam. Below is a playful list of Dutch inventions and discoveries, each with the museum where you can see it. Pick a colour to filter. Then test yourself: how much of what the Dutch like to tell is true? Are carrots really orange to honour the House of Orange? And what does Leiden have to do with the word battery?
Inventions and discoveries with a Dutch stamp. Pick a colour.
Spectacle makers in Middelburg, often named as Zacharias Janssen, are linked to the first compound microscope.

One day, four moments. How to get the most out of your visit.
Six places to complete your museum day.
The museum of Dutch science: Van Leeuwenhoek's microscopes, Huygens' clocks, the Leyden jar and Kamerlingh Onnes' cold lab.
The oldest museum in the Netherlands, with the huge electrostatic machine of 1784, fossils and instruments in beautiful wooden cases.
From light bulb to cassette and CD: the story of the company that made Eindhoven, in the old factory where it began.
Working windmills, including a sawmill. See how wind powered the Golden Age.
The Huygens family's country house in Voorburg, now a museum about Constantijn and Christiaan Huygens.
Walk inside the Eastern Scheldt barrier and see how the Netherlands holds back the sea.
The Dutch love a good story. Guess first, then see the answer.
Carrots are orange to honour the House of Orange.
Dutch growers did make the orange carrot popular in the 17th century, but there is no evidence it was for Orange. A lovely story, nothing more.
The word battery comes from Leiden.
Almost! Benjamin Franklin called a row of linked Leyden jars a battery, like a battery of cannon. That is how the word came to electricity.
A Dutchman designed one of the first combustion engines.
Around 1673 Christiaan Huygens designed an engine driven by small gunpowder explosions in a cylinder. It was never really put to use, but it is a distant ancestor of the car engine.
The Dutch invented the sextant.
The sextant comes from England and America, around 1730. But Amsterdam mapmakers such as Blaeu made the best sea charts of their age.
Bluetooth is partly Dutch.
Jaap Haartsen, a Dutch engineer at Ericsson, laid the foundations in 1994. He is in the US National Inventors Hall of Fame.
The bicycle is a Dutch invention.
The bicycle's ancestor comes from Germany, in 1817. But the Netherlands has more bicycles than people.
The telescope is Dutch.
The oldest known patent application for a telescope is by Hans Lipperhey of Middelburg, in 1608. Galileo heard about it and built his own.
The world's first shares were Dutch.
From 1602 the VOC sold shares that could be freely traded. That was the start of the modern stock exchange, in Amsterdam.
He had no university education and spoke no Latin. Yet he was the first person to see a world nobody knew existed.
Antoni van Leeuwenhoek sold cloth in Delft. Drapers ground small lenses to check the quality of thread, and Van Leeuwenhoek made his so well that they magnified hundreds of times. He looked at everything: rainwater, pepper, the plaque on his own teeth. In 1676 he wrote to the Royal Society in London that he had seen tiny moving creatures. The scholars did not believe him at first, until they saw it themselves. He became one of the fathers of microbiology. A few of his tiny microscopes have survived.
