  • Microscope is interesting.
  • Hello there, we're about to embark on a journey to study the evolution of microscopy into the cornerstone of cell theory.
  • Do you know that the invention of the microscope may be traced back to the Italian practice of polishing lenses for spectacles in the 14th century?
  • And in 1665, Robert Hooke created a practical British compound microscope.
  • And around 1670 Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa.
  • The origin of the microscope can be traced back to the Italian art of polishing lenses for spectacles in the 14th centuryIn 1590, Dutch lens grinders Hans and Zacharias Janssen used the technology to create the first microscope by combining two lenses in a tube.
  • The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.
  • His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
