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.
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.
Van Leeuwenhoek was the first to observe microscopic organisms, using simple single-lensed microscopes of his own design. [1] 1729–1799 Lazzaro Spallanzani: Italian Proved that bacteria did not arise due to spontaneous generation by developing a sealed, sterile broth medium. [2] [3] 1749–1823 Edward Jenner: English
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 ...
1661: Marcello Malpighi observed capillary structures in frog lungs. 1665: Robert Hooke publishes Micrographia, a collection of biological drawings. He coins the word cell for the structures he discovers in cork bark. 1674: Antonie van Leeuwenhoek improves on a simple microscope for viewing biological specimens (see Van Leeuwenhoek's microscopes).
In 1661, 1664 and 1665, the blood cells were discerned by Marcello Malpighi. In 1678, the red blood corpuscles was described by Jan Swammerdam of Amsterdam, a Dutch naturalist and physician. The first complete account of the red cells was made by Anthony van Leeuwenhoek of Delft in the last quarter of the 17th century.
The trophozoite form of Giardia was first observed in 1681 by Van Leeuwenhoek during observation of his own stool. [81] Volvox (1700)- Volvox is a genus of chlorophytes, a type of green algae. It forms spherical colonies of up to 50,000 cells. They live in a variety of freshwater habitats, and were first reported by Van Leeuwenhoek in 1700.
Leeuwenhoek named these "animalcules," which included protozoa and other unicellular organisms, like bacteria. Though he did not have much formal education, he was able to identify the first accurate description of red blood cells and discovered bacteria after gaining interest in the sense of taste that resulted in Leeuwenhoek to observe the ...
