Microorganisms are discovered today by two people using primitive microscopes: Robert Hooke Robert Hooke In 1673, Hooke built the The first Gregorian telescope, and then he observed the rotations of the planets Mars and Jupiter. Hooke’s 1665 book « Micrographs » inspired the study of microscopy. By looking at microscopic fossils, Hooke endorsed the theory of biological evolution. https://en.wikipedia.org › Wiki › Robert_Hooke
