Zacharias and Hans Janssen - On the early 13th century, spectacle makers were producing lenses for glasses. The early simple “microscopes” were known as “flea glasses” because they were used to study small insects. A father- son duo, created the first microscope in the 1590s., Galileo Galilei - In the year 1625, He perfects the principle of microscope., Robert Hooke - In 1665, an English physicist, looked at a sliver of cork through a microscope lens and notice some “pores” or “cells” in it, Anton van Leeuwenhoek - in 1674 a simple microscope with only one lens to examine blood, yeast, insects and many other tiny objects, Richard Zsigmondy - In year 1925 he developed the ultra-microscope that could study objects below the wavelength of light and won a Nobel Prize in Chemistry in 1925, Frits Zernike - The phase- contrast microscope he invented in 1932, allows the study of colorless and transparent biological materials. Little was done to improve the microscope until the middle of the 19th century when great strides were made and quality instruments like today’s microscope emerged.,
