  • "There can be no doubt, however, that Leeuwenhoek was a master when it came to the microscope. No one knows why he took an interest in the invention, but he may have begun by experimenting with the weak magnifying glasses that drapers commonly used to detect flaws in fabric. In a surprisingly short time Leeuwenhoek became an expert lens grinder and glass-blower. Although he built only single-lens microscopes, they were superior to all others of the period, including the compound ones that used several lenses to boost their viewing power. ... For clarity and power, it soon became evident that Leeuwenhoek's microscopes could not be equaled. One Leeuwenhoek lens, now held by the University of Utrecht Museum, was capable of portraying structures only 0.00075 millimeters thick--a feat not equaled until the 19th century.

    "Fearing that he would lose his tenuous place in the scientific world if he revealed his secrets, Leeuwenhoek refused to share his methods of magnification with anyone; to this day, we do not fully understand his techniques. His observations, however, were a different matter; he shared them with any number of friends and colleagues."
