Antonie Philips van Leeuwenhoek [note 2] FRS (/ ˈ ɑː n t ə n i v ɑː n ˈ l eɪ v ən h uː k,-h ʊ k / AHN-tə-nee vahn LAY-vən-hook, -huuk; Dutch: [ˈɑntoːni vɑn ˈleːu.ə(n)ˌɦuk] ⓘ; 24 October 1632 – 26 August 1723) was a Dutch microbiologist and microscopist in the Golden Age of Dutch science and technology.
Birth - Death Microbiologist Nationality Contribution summary 1632–1723 Antonie van Leeuwenhoek: Dutch Considered to be the first acknowledged microscopist.Van Leeuwenhoek was the first to observe microscopic organisms, using simple single-lensed microscopes of his own design.
Once discovering these types of cells, Leeuwenhoek saw that the fertilization process requires the sperm cell to enter the egg cell. This put an end to the previous theory of spontaneous generation. After reading letters by Leeuwenhoek, Hooke was the first to confirm his observations that were thought to be unlikely by other contemporaries. [4]
Microorganisms are said to have been first directly observed in the 1670s by Anton van Leeuwenhoek, an early pioneer in microbiology, considered "the Father of Microbiology". Leeuwenhoek is said to be the first to see and describe bacteria in 1674, yeast cells, the teeming life in a drop of water (such as algae), and the circulation of blood ...
1675: Anton van Leeuwenhoek: observes microorganisms using a refined simple microscope. 1676: Ole Rømer: first measurement of the speed of light. 1687: Sir Isaac Newton: classical mathematical description of the fundamental force of universal gravitation and the three physical laws of motion.
1674: Antonie van Leeuwenhoek improves on a simple microscope for viewing biological specimens (see Van Leeuwenhoek's microscopes). 1825: Joseph Jackson Lister develops combined lenses that cancelled spherical and chromatic aberration. 1846: Carl Zeiss founded Carl Zeiss AG, to mass-produce microscopes and other optical instruments.
Antonie van Leeuwenhoek revealed by means of microscopy the previously unknown world of microorganisms, laying the groundwork for cell theory. The growing importance of natural theology, partly a response to the rise of mechanical philosophy, encouraged the growth of natural history (although it entrenched the argument from design).
Animalcule (Latin for 'little animal'; from animal and -culum) is an archaic term for microscopic organisms that included bacteria, protozoans, and very small animals.The word was invented by 17th-century Dutch scientist Antonie van Leeuwenhoek to refer to the microorganisms he observed in rainwater.
