Reproduction of an early electron microscope constructed by Ernst Ruska in the 1930s. Many developments laid the groundwork of the electron optics used in microscopes. [2] One significant step was the work of Hertz in 1883 [3] who made a cathode-ray tube with electrostatic and magnetic deflection, demonstrating manipulation of the direction of an electron beam.
IEEE Founders Medal (1981) Scientific career. Institutions. RCA. James Hillier, OC (August 22, 1915 – January 15, 2007) was a Canadian - American scientist and inventor who designed and built, with Albert Prebus, the first successful high-resolution electron microscope in North America in 1938. [1]
1936: Erwin Wilhelm Müller invents the field emission microscope. 1938: James Hillier builds another TEM. 1951: Erwin Wilhelm Müller invents the field ion microscope and is the first to see atoms. 1953: Frits Zernike, professor of theoretical physics, receives the Nobel Prize in Physics for his invention of the phase-contrast microscope.
Electron microscope constructed by Ernst Ruska in 1933. Ernst August Friedrich Ruska (German pronunciation: [ɛʁnst ˈʁʊskaː] ⓘ; 25 December 1906 – 27 May 1988) [1] was a German physicist who won the Nobel Prize in Physics in 1986 for his work in electron optics, including the design of the first electron microscope.

Albert Victor Crewe (February 18, 1927 – November 18, 2009) was a British-born American physicist and inventor of the modern scanning transmission electron microscope [1] capable of taking still and motion pictures of atoms, a technology that provided new insights into atomic interaction and enabled significant advances in and had wide-reaching implications for the biomedical, semiconductor ...
Clocks; a watch-maker seated at his workbench. Chronometry[a] or horology[b] (lit. 'the study of time') is the science studying the measurement of time and timekeeping. [3] Chronometry enables the establishment of standard measurements of time, which have applications in a broad range of social and scientific areas.
