The history of microscopes begins with the history of glasses, in the 13th century Salvino D'Armate from Italy, made the first eye glass giving people an element of magnification to one eye. In the fourteenth century Italians started making spectacles to improve people’s eyesight. In 1590 two Dutch men, Zacharias Jansen and his father Hans made the first ever microscope by placing two lenses inside of a tube. They discovered that the object they were looking at was way bigger than any magnifying glass could achieve. This wasn’t entirely successful however because you could only magnify something nine times with this device. It was a treat for the wealthy more than anything. Anton Von Leeuwenhoek was the first man to invent and use a real microscope. He used a process to grind and polish the glass to create his tube with a magnification power of 270x. Leeuwenhoek was the first man to see and describe bacteria, yeast plants, the life in a single drop of water and explore our own blood. Later in the very same decade Robert Hooke takes Leeuwenhoek’s work as well as his own and publishes it in the book Micrographia. Over the next two hundred years microscopes didn’t change much apart from some small modifications making them easier to use, an important discovery being that using two different types of glass reduced the halo light glare. Joseph Jackson Lister found that using several weaker lenses gave good magnification without blurring the image. In 1903 Richard Zsigmondy develops the ultra-microscope and is able to study objects below the wavelength of light. In 1938 Ernst Ruska develops the electron microscope improving the
