Make Your Own Van Leeuwenhoek Microscope
Introduction
Antonie van Leeuwenhoek was a wealthy cloth merchant who lived in the city of Delft, in the Netherlands, from 1632 to 1723. He is best known for his pioneering work on microscopy: from 1673 onwards he created as many as 500 microscopes and from these made numerous significant discoveries. This included determining the existence of single-celled organisms, a discovery that ironically brought his scientific credibility into question for some time.
The success of these microscopes can be attributed to many things, but a number of technical matters stand out. First, his microscopes relied on a single lens. Compound microscopes (those with more than one lens in the light path) theoretically provide better resolution, but they are also much more technically challenging to fabricate. As well, Leeuwenhoek devised a relatively simple means to produce his single lens. In particular, his methodology appears to have reduced the need for precise grinding techniques, and grinding was a laborious and technically difficult process.
The few examples of Leeuwenhoek’s microscopes that remain today are elegant creations of brass or silver with many working parts. Although much less complex than modern microscopes, replicas of meta

Imagine trying to cope with a pandemic like COVID-19 in a world where microscopic life was unknown. Prior to the 17th century, people were limited by what they could see with their own two eyes. But then a Dutch cloth merchant changed everything.
His name was Antonie van Leeuwenhoek, and he lived from 1632 to 1723. Although untrained in science, van Leeuwenhoek became the greatest lens-maker of his day, discovered microscopic life forms and is known today as the “father of microbiology.”
Visualizing ‘animalcules’ with a ‘small see-er’
Van Leeuwenhoek didn’t set out to identify microbes. Instead, he was trying to assess the quality of thread. He developed a method for making lenses by heating thin filaments of glass to make tiny spheres. His lenses were of such high quality he saw things no one else could.
This enabled him to train his microscope – literally, “small see-er” – on a new and largely unexpected realm: objects, including organisms, far too small to be seen by the naked eye. He was the first to visualize red blood cells, blood flow in capillaries and sperm.
Van Leeuwenhoek was also the first human being to see a bacterium – and the importance of this discovery for microbiology and medicine can hardly be overstated. Yet he was reluctant to publish his fi
