hans janssen is the brother of zacchariah janssen
Robert Hooke invented the first compound microscope.
Zacharias and Hans Janssen developed the compound microscope in the 16th century. It consisted of a tube with lenses at each end, allowing for greater magnification than a simple microscope. This invention revolutionized the field of microscopy and laid the foundation for modern optical instruments.
The first microscope to be developed was the optical microscope. An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Zacharias Janssen. Van Leeuwenhoek improved a microscope and first described cells seen in cork tissue. He called them cells as they looked like little rooms, similar to ones that monks lived in.
nothing it looks like a normal hair
Zacharias Janssen discovered the compound microscope
Zacharias Janssen's first microscope was called the "simple microscope" or "single lens microscope." It consisted of a single convex lens and was an early version of the compound microscope.
In 1590 Zacharias Janssen (Netherlands) invented the compound microscope.
The compound microscope was invented by Zacharias Janssen in the late 16th century, although others like Hans and Zacharias Janssen, Hans Lippershey, and Hans Martens claim to have contributed to its development. The electron microscope was later invented in the 20th century by Ernst Ruska and Max Knoll.
The invented the microscope and telescope. The invented the microscope and telescope.
He made his first simple lens microscope in 1595.
Zacharias Janssen is credited with inventing the first compound microscope, along with his father Hans in the late 16th century. This microscope used multiple lenses to magnify objects, leading to significant advancements in the field of microscopy.

Zacharias Janssen (Netherlands) invented the telescope and perhaps the compound micoscope in 1590.
FYI he did not invent the microscope the Romans did search it on the web
