16761676 − − Antonie van LeeuwenhoekAntonie van Leeuwenhoek, Dutch microscopist first saw bacteria , Dutch microscopist first saw bacteria with a single-lens microscope he built. He published observations in letters with a single-lens microscope he built. He published observations in letters to the Royal Society of London. Bacteria were at the limit of his simple to the Royal Society of London. Bacteria were at the limit of his simple lenses, and were his most remarkable microscopic discovery. lenses, and were his most remarkable microscopic discovery.
