Heinrich Rudolf Hertz (/ h ɜːr t s / HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism.
The publication of the equations marked the unification of a theory for previously separately described phenomena: magnetism, electricity, light, and associated radiation. Since the mid-20th century, it has been understood that Maxwell's equations do not give an exact description of electromagnetic phenomena, but are instead a classical limit ...
This may be the most remarkable contribution of Maxwell's work, enabling him to derive the electromagnetic wave equation in his 1865 paper A Dynamical Theory of the Electromagnetic Field, showing that light is an electromagnetic wave. This lent the equations their full significance with respect to understanding the nature of the phenomena he ...
Hertz published his work in a book titled: Electric waves: being researches on the propagation of electric action with finite velocity through space. [134] The discovery of electromagnetic waves in space led to the development of radio in the closing years of the 19th century.
[11] [page needed] The unit volt is named for his contributions. 1800 – William Herschel discovers infrared radiation from the Sun. 1800 – William Nicholson, Anthony Carlisle and Johann Ritter use electricity to decompose water into hydrogen and oxygen, thereby discovering the process of electrolysis, which led to the discovery of many ...
A theory of electromagnetism, known as classical electromagnetism, was developed by several physicists during the period between 1820 and 1873, when James Clerk Maxwell's treatise was published, which unified previous developments into a single theory, proposing that light was an electromagnetic wave propagating in the luminiferous ether.

Heinrich Rudolf Hertz (1856–1894) proved the existence of electromagnetic radiation. In an 1864 presentation, published in 1865, James Clerk Maxwell proposed theories of electromagnetism and mathematical proofs demonstrating that light, radio and x-rays were all types of electromagnetic waves propagating through free space.
The IEEE Heinrich Hertz Medal was a science award presented by the IEEE for outstanding achievements in the field of electromagnetic waves.The medal was named in honour of German physicist Heinrich Hertz, and was first proposed in 1986 by IEEE Region 8 as a centennial recognition of Hertz's work on electromagnetic radiation theory from 1886 to 1891.
