Hans Janssen and his son Zacharias Janssen, Dutch spectacle-makers, are frequently cited as having invented the first compound microscope in 1590, but there is a good deal of dispute. They may not have. Zacharias Janssen was the one who actually made the claim, and in the middle of the 1600's. A number of historians, however, agree that it is imporbable that 1590 is correct. There is a good deal of evidence that Zacharias Janssen was born somewhere around 1590. A link is provided to the Wikipedia article on the optical microscope where a brief history of the device can be reviewed.

∙ 14y agoAnton Von Leeuwenhook first used a microscope in about 1675, and discovered many things. However, it seems that the microscope had already been invented, about 85 years earlier, by spectacle lens makers Hans and Zacharias Janssen, in 1590.
Even Robert Hooke used a microscope in 1660s. So Leeuwenhook, despite the tremendous advances he made to science with his developments of the microscope, does not appear to be the person who actually invented it.

Why did Zacharias Janssen invent the microscope?
The simplest answer is that they were created to see things, or details, that are too small for the human eye to see. Early tradesmen used simple lenses to see the intricate lines of engravings, or the clasps and fittings on jewelry. When eyeglass makers began combining pairs of carefully-ground lenses, they discovered the principle of optical magnification that is the basis for the microscope (and the telescope). In the case of the microscope, there were immediate practical applications in biology, anatomy, and miniature mechanical gearing.
