Detailed explanation-1: -Anton van Leeuwenhoek (October 24, 1632–August 30, 1723) invented the first practical microscopes and used them to become the first person to see and describe bacteria, among other microscopic discoveries.

Detailed explanation-2: -The entire instrument was only 3-4 inches long, and had to be held up close to the eye; it required good lighting and great patience to use. Compound microscopes (that is, microscopes using more than one lens) had been invented around 1595, nearly forty years before Leeuwenhoek was born.

Detailed explanation-3: -How did Antonie van Leeuwenhoek become famous? Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa.

Detailed explanation-4: -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.
