    Inventor Karl Braun’s original 1897 cathode ray tube birthed the oscilloscope, using CRTs to visualize electronic signal waveforms. Early 20th century oscilloscopes relied on small 3-inch CRTs. However, by 1946 the 10-inch DuMont 208 set the standard form factor.

    In 1874, he discovered that a point-contact metal–semiconductor junction rectifies alternating current. [7] He became director of the Physical Institute and professor of physics at the University of Strassburg in 1895. In 1897, he built the first cathode-ray tube (CRT) and cathode ray tube oscilloscope. [8]

    The cathode ray tube (CRT), invented by German physicist Karl Ferdinand Braun in 1897, is an evacuated glass envelope containing an electron gun (a source of electrons) and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons. When electrons strike the fluorescent screen, light is emitted.
