The History of Microscopes and the Cell Theory

Jan 1, Hans Jansen and his son, Zacharias, become the first to have any sort of documentation that supports that they created the idea of the microscope. Hans and Zacharias Jansen invent their own design of the microscope compound microscope that could only be used for opaque objects and has a magnification of 20x. Sep 1, With the help of his own microscope, Robert Hooke, the Secretary of Royal Society, publishes a folio of thirty-eight copper-plate illustrations of objects drawn titled, "Microgphia".
The development of the microscope and the creation of the cell theory is an example to support this idea. Each scientist that I researched added.

The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. While the invention of the telescope made the Cosmos accessible to human observation, the microsope opened up smaller worlds, showing what living forms were composed of. The cell was first discovered and named by Robert Hooke in He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells cork as it appeared under the microscope. The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek , who in described the algae Spirogyra.
Microscopes let us view an invisible world — the objects around us that are too small to be seen with the naked eye. This timeline provides a look at some of the key advances in microscopy. The Nimrud lens — a piece of rock crystal — may have been used as a magnifying glass or as a burning-glass to start fires by concentrating sunlight. The first vision aid, called a reading stone, is invented. It is a glass sphere placed on top of text, which it magnifies to aid readability. Muslim scholar Ibn al-Haytham writes his Book of Optics. It eventually transforms how light and vision are understood.

Toggle navigation. Cells were too small to be seen. But with the invention of the microscope, an entirely new world was discovered, where very large objects like humans are in fact made up of billions of tiny individual pieces called cells. Cell first observed Robert Hooke, an English scientist, discovered a honeycomb-like structure in a cork slice using a primitive compound microscope. He only saw cell walls as this was dead tissue. He coined the term "cell" for these individual compartments he saw. First living cells seen Anton van Leeuwenhoek, a Dutch biologist, looks at pond water with a microscope he made lenses for.
