Antonie van Leeuwenhoek is the father of microbiology. He made his own microscopes and used his designs. He viewed organisms with microscope in 1676.
He was first to see organisms tiny enough, which could not be seen with naked eye. He made approximately 500 lenses and around 20-25 microscopes with one lens. He was supposed to have microscopes which could magnify the object five hundred times.
