The main idea here is understanding who first created a microscope that uses two lenses to magnify objects, rather than a single lens. This invention, the first compound microscope, is credited to Zacharias Janssen (often noted with his father Hans Janssen) in the Netherlands toward the end of the 16th century. Their two-lens arrangement in a tube combined an objective and an eyepiece to produce greater magnification than any simple microscope could offer, marking the birth of compound optical instruments. Later on, Anton van Leeuwenhoek popularized powerful single-lens microscopes and made foundational discoveries in microbiology, but he did not invent the first compound microscope. The other two individuals were key figures in medicine—Jenner in vaccination and Blundell in obstetrics—yet they are not associated with inventing the first compound microscope.
