Antonie van Leeuwenhoek
c. 1632–1723 · Delft · Often called the “Father of Microbiology.”
Contribution
Built high-quality single-lens microscopes and was the first to observe and describe single-celled organisms (“animalcules”) — bacteria and protozoa — in letters to the Royal Society (1670s).
Why It Still Matters
Microbiology begins with seeing. Direct observation made microbes real objects of science and opened the path to germ theory centuries later.
