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 Maxwellians is a book by Bruce J. Hunt, published in 1991 by Cornell University Press; a paperback edition appeared in 1994, and the book was reissued in 2005.It chronicles the development of electromagnetic theory in the years after the publication of A Treatise on Electricity and Magnetism by James Clerk Maxwell.

Heinrich Hertz. In 1887, the German physicist Heinrich Hertz in a series of experiments proved the actual existence of electromagnetic waves, showing that transverse free space electromagnetic waves can travel over some distance as predicted by Maxwell and Faraday
German physicist Heinrich Hertz proves the existence of electromagnetic waves, including what would come to be called radio waves. 1888: Italian physicist and electrical engineer Galileo Ferraris publishes a paper on the induction motor, and Serbian-American engineer Nikola Tesla gets a US patent on the same device [4] [5] 1890
The relationships amongst electricity, magnetism, and the speed of light can be summarized by the modern equation: = . The left-hand side is the speed of light and the right-hand side is a quantity related to the constants that appear in the equations governing electricity and magnetism.
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 electric battery became standard equipment in every experimental laboratory and heralded an age of practical applications of electricity. [11] [page needed] The unit volt is named for his contributions. 1800 – William Herschel discovers infrared radiation from the Sun.
