One possibility is that the microscope was invented in the Netherlands. The precise date of the invention of the microscope is unknown, but it is suggested that the first microscope was developed in the Netherlands by three men, Zaccharias Janssen, Hans Janssen, and Antony Van Leeuwenhoek.

How did the Invention of the Microscope Happen?

Zaccharias Janssen, and his father, Hans, began experimenting with the use of different lenses to magnify objects in the 1590s. Zaccharias and Hans were spectacle makers who worked with lenses every day. Together, they discovered that placing a lens in a tube was a fantastic way to increase the magnification of the object they were observing.

Later, in the late 17th century, Antony Van Leeuwenhoek took the invention of the microscope one step further, building upon the discoveries of the Janssen family to create and use a real microscope in the same way microscopes are used today.

Controversy over Who Invented the Microscope?

Like many inventions, the development of the first microscope is contested, though most people agree on attributing credit for this invention to the Janssens and Antony Van Leeuwenhoek.

Timeline of the Invention of the Microscope

Glass was invented in the first century, and the Romans were known to have investigated the use of glass for viewing objects, and the properties of glass which made objects appear larger.

The first eyeglasses were invented

in the 13th century, most likely by someone in Northern Italy. These provided the wearer with a small level of magnification. Early on the use of glass for magnifying objects was limited to 6x to 10x levels of magnification. Primarily these magnifying glasses were used to inspect small insects like fleas … this resulted in the name “flea glasses” for early magnifying glasses.

This early work with glass resulted in the invention of the first compound microscope by the Janssen father and son duo. While the Janssen’s microscope was little more than a tube with lenses at the near and far end (it may not resemble what you think of when you picture a compound microscope), their design was passed along through a letter to a Dutch diplomat (William Boreel) who shared details of the invention with the physician of the French King in the 1650s.

Anton van Leeuwenhoek: Microscopes for Science

A Dutch scientist by the name of Anton van Leeuwenhoek improved the design of the Janssen family in the late 17th century. By developing new ways to grind and polish lenses, Leeuwnehoek was able to produce a lens tube with magnifying power of 270x! This was vastly superior to any other microscope currently in use at the time (the best alternatives could only produce 50x magnification).

Armed with a superior microscope Leeuwenhoek made his mark on science as the first man to see and describe bacteria, yeast plants and the life which existed within a single drop of water.

His work was verified and built upon by English scientist Robert Hooke, who went on to publish the first work of microscopic studies in the year 1665, Micrographia.
