The earliest compound microscope is often credited to Dutch spectacle makers Hans and Zacharias Janssen around 1590. Their device used multiple lenses to magnify small objects, though with limited clarity. In the mid‑17th century, Antonie van Leeuwenhoek, using single‑lens microscopes of remarkable quality, observed bacteria, protozoa, and blood cells, earning him the title “father of microbiology.”\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection class=\"b_paragraph b_paragraph_selected\" data-md-index=\"3\" data-bm=\"61\" tabindex=\"0\"\u003e\n\u003cp\u003eRobert Hooke’s 1665 publication\u003cspan\u003e \u003c\/span\u003e\u003cem\u003eMicrographia\u003c\/em\u003e\u003cspan\u003e \u003c\/span\u003eintroduced detailed illustrations of microscopic structures, including the first recorded use of the term “cell.” Over the 18th and 19th centuries, improvements in lens grinding, illumination, and mechanical stability greatly enhanced image resolution.
