The first historical record of the use of a lens, the Nineveh crystal, is believed to have been used to magnify objects up to three times their size. In modern times, three fathers of microscopy stand out for their contributions: (a) Zacharias Jansen, who made a true breakthrough in microscopy by introducing the first combination of two lenses; (b) Anton van Leeuwenhoek, one of the most renowned microscopists of antiquity, to whom the construction of hundreds of microscopes, as well as the description and illustration of beings such as microorganisms, is attributed; and finally (c) Robert Hooke, who continues to fascinate everyone who delves into one of his greatest legacies: the book Micrographia, considered the first treatise on illustrated microscopy. Giovanni Faber, on his part, never made a microscope but was the first to use the term “microscope,” from the Greek words: mikros (small) and skopein (to look), meaning to observe the small.
