Antony van Leeuwenhoek first discovered microscope (single lens)
Commonly known as the father of microbiology and considered the first microbiologist.
Antony van Leeuwenhoek(1677) first observed microorganisms (bacteria, yeast, protozoa) seen in water, faeces, scrapings etc under his own microscope.
He was basically a cloth maker and tailor by trade, was also a surveyor and the official wine taster.
His interest in microscopes was probably related to the use of magnifying glasses to examine fabrics.
He transmitted his findings in a series of more than 200 letters to the royal Society of Landon.
He described such tiny creatures as “dierkens” or “animalcula viva” which were translated in english as “animalcules”.
He gave the first complete account and description of the red blood cell, demonstrated the capillary connections between arteries and veins.
