A Brief History of the Microscope

The microscope is perhaps the most interesting and well-known item that you can see in the science labs all over the world. No doubt that you have even used it at one point in your life, particularly during your school days. But have you ever stopped to think who the genius behind this device was and how he came up with the idea? If you have not, then there is no need to be ashamed. You're not the only one. However, your days of microscope cluelessness are coming to an end. It cannot be denied that man has a curiosity about things that are not visible to the naked eye. That curiosity brought about the first microscope prototype, a single convex lens magnifier. In the times of Pliny the Elder in the First Century AD, people used of crystal or simply glass in order to envisage objects that are not normally seen. These globes were shaped just so, in order for the person seeing to view the objects in a magnified state. This paved way to the discovery that light from the sun that shone into the lens and focused on one point caused the parchment to burn. This discovery eventually came to use later on. Although most people think that it was Anthony van Leeuwenhoek who made first the microscope, there were actually several more early prototypes made by the Romans, Digges of England and Hans and Zacharias Janssen of Holland. However, it cannot be argued that these previous models paled in comparison to Leeuwenhoek's model. What he did was expand from the norm and proceed to ground and polish up a small glass ball into a lens, thereby making a magnification of 270 times the normal view. This made it the first real and practical single lens microscope. It is obviously called thus because it has only one lens, convex glass lens attached to a metal holder. The first model used screws as knobs in order for you to focus. Leeuwenhoek was not content with this merely inventing microscope. He proceeded to study further, constructing around four hundred microscope prototypes in his lifetime. Along the way, he also discovered things like bacteria and spermatozoa. The invention of the microscope paved the way for many other amazing discoveries. The compound microscope, invented in the seventeenth century, enabled English scientist Robert Hooke to discover that all living cells are made up of cells. Frenchman Louis Pasteur discovered yeast fungus, Robert Koche discovered the tubercle and cholera bacilli, German bacteriologist Karl J. Ebert discovered Eberthella Thyphosa, to name a few. There have been more amazing discoveries that have been brought about by the microscope. It is singularly one of the most important inventions of all time. And we have the innate curiosity of man to thank for that.
