Hans and Zacharias Janssen are most famous for inventing the first compound microscope in the late 16th century. Their creation revolutionized the field of optics and paved the way for advancements in microscopy and scientific research.
There is a lot of confusion and controversy surrounding the invention of the microscope. If Zacharias Janssen invented the compound microscope on the claimed dates between 1590 and 1618 (most commonly given dates of 1590 and 1595), Janssen could have been a child, or not even born yet, as his birth date has been given as 1580, 1585, and 1588. Janssen was a one time neighbor to Hans Lippershey, another inventor laying claim to the microscope. Testimonies offered from various family and friends have also been inconsistent, so the actual inventor, date, and other details surrounding the microscope are impossible to know for fact. Janssen was a known counterfeiter and fraud on other matters, so it is possible he did not invent the microscope at all.
The first microscope was made around 1595 in Middelburg, Holland. Three different eyeglass makers have been given credit for the invention: Hans Lippershey (who also developed the first real telescope); Hans Janssen; and his son, Zacharias. The coining of the name "microscope" has been credited to Giovanni Faber, who gave that name to Galileo Galilei's compound microscope in 1625. (Galileo had called it the "occhiolino" or "little eye".) The most common type of microscope-and the first to be invented-is the optical microscope. This is an optical instrument containing one or more lenses that produce an enlarged image of an object placed in the focal plane of the lens(es). There are, however, many other microscope designs. "Microscopes" can largely be separated into three classes: optical theory microscopes (Light microscope), electron microscopes (e.g.,TEM), and scanning probe microscopes (SPM). Optical theory microscopes are microscopes which function through the optical theory of lenses in order to magnify the image generated by the passage of a wave through the sample. The waves used are either electromagnetic (in optical microscopes) or electron beams (in electron microscopes). The types are the Compound Light, Stereo, and the electron microscope.

Microscopes were invented to let people look at very small things, most notably water, and see what is in them. The first was invented in 1590, by two eyeglass makers (Hans Lippershey and Hans Janssen).

Galileo is credited with the first compound microscope. Zacharias Janssen invented the microscope that we use today.

There is limited historical information about Zacharias Janssen's personal life, including details about his children. Most records focus on his contributions to optics and the invention of the compound microscope rather than his family. Consequently, the names and ages of any children he may have had are not well-documented.
