Detailed explanation-1: -Leeuwenhoek’s skill at grinding lenses, together with his naturally acute eyesight and great care in adjusting the lighting where he worked, enabled him to build microscopes that magnified over 200 times, with clearer and brighter images than any of his colleagues could achieve.

Detailed explanation-2: -Leeuwenhoek is universally acknowledged as the father of microbiology. He discovered both protists and bacteria [1]. More than being the first to see this unimagined world of ‘animalcules’, he was the first even to think of looking-certainly, the first with the power to see.

Detailed explanation-3: -Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.

Detailed explanation-4: -Although the craftsmanship and the design of the Hooke microscope were excellent, it failed to provide good optical performance than the Leeuwenhoek microscope.
