Phase Morphology Investigation Microscopic Tools, Tips, and Selected Scanning Electron Photomicrographs 

Credit for the first microscope is usually given to Zacharias Janssen aroimd the year 1595. Because Zacharias was very young at that time, it is possible that his father, Hans, made the first one, but young Zach took over the introduction of these seemingly magic observation tools. 

The first compound microscope introduced by the Janssens was simply a tube with lenses at each end. The magnification of these early scopes ranged from 3x to 9x, depending on the size of the diaphragm openings. 

Hooke balanced his inventions with more pure research. He improved early compound microscopes around 1660. In Micrographia (1665), he coined the word cell to describe the features of plant tissue (cork from the bark of an oak tree) he was able to discover under the microscope. He applied his extensive mathematical knowledge in formulating the theory of planetary movement, which provided a basis for Sir Isaac Newton s theories of gravitation. In 1667 he discovered the role of oxygenation in the respiratory system. 

But also Antoni van Leeuwenhoek was a man with many talents his most important attributes were creativity, power of observation, and ingenuity. Leeuwenhoek was a common man without any fortune or formal education, so he had to work for a living. Leeuwenhoek made simple (one-lens) microscopes. He was not the first person to build a microscope, but the microscopes that he could build were the best ones of that time period. Leeuwenhoek was the first person to describe bacteria (from teeth scrapings) and protozoan (from pond water) and also helped to prove the theory of blood circulation. He gained much of his inspiration from reading Hooke s Micrographia.
