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.
He is credited as one of the first scientists to investigate living things at microscopic scale in 1665, [6] using a compound microscope that he designed. [7] Hooke was an impoverished scientific inquirer in young adulthood who went on to become one of the most important scientists of his time. [8]
The company of Carl Zeiss exploited this discovery and becomes the dominant microscope manufacturer of its era. 1928: Edward Hutchinson Synge publishes theory underlying the near-field scanning optical microscope; 1931: Max Knoll and Ernst Ruska start to build the first electron microscope. It is a transmission electron microscope (TEM).
Zacharias Janssen; also Zacharias Jansen or Sacharias Jansen; 1585 – pre-1632 [1]) was a Dutch spectacle-maker who lived most of his life in Middelburg.He is associated with the invention of the first optical telescope and/or the first truly compound microscope, but these claims (made 20 years after his death) may be fabrications put forward by his son.
Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
Quantum optics is the study of the nature and effects of light as quantized photons. The first indication that light might be quantized came from Max Planck in 1899 when he correctly modelled blackbody radiation by assuming that the exchange of energy between light and matter only occurred in discrete amounts he called quanta. It was unknown ...
A.C. Gilbert is a legend in these parts, born and raised in Salem, where he developed a passion for competition and innovation and launched his first business enterprise.
Spencer’s first microscopes were available for purchase in 1838. [2] Previous to Spencer’s invention, European manufacturers held a monopoly on research-quality microscopic equipment. [ 3 ] At least one of Spencer’s microscopes survives and is currently held by the Smithsonian Institution.
