One of the first microscopes was built by a lensmaker in the Netherlands in 1590. It was a simple device with one lens. In 1625, Italian scientist Galileo Galilei made the first compound microscope. ---- The magnified view appears as a so-called ‘virtual image’ behind the target. Many microscopes today also have a light source behind the target to illuminate it.
