Heinrich Hertz Facts
Heinrich Rudolf Hertz (22 February 1857 to 1 January 1894) was a German physicist who proved the existence of electromagnetic waves. The scientific unit of frequency was named the Hertz in his honor.
Interesting Heinrich Hertz Facts:
Heinrich Rudolf Hertz was born in Hamburg, Germany and was the son of a prosperous barrister.
He attended the Gelhrtenschule des Johanneums grammer school where he showed a gift for languages, learning Latin, Sanskrit, and Arabic.
In 1880 he received a PhD cum laude from the University of Berlin, and in 1883 he took a position as lecturer in theoretical physics at the University of Kiel.
From 1885 to 1889 while he was professor of physics at the Karlsruhe Polytechnic, he produced electromagnetic waves and measured their length and velocity.
His experiments proved the behavior of the electromagnetic waves predicted by James Maxwell, and he built an apparatus to measure the velocity of the electromagnetic waves.
He proved Maxwell's theory that light and heat are electromagnetic radiations.
From 1886 to 1894 he held the post of Professor of Physics and Director of the Physics Institute in Bonn, where he continued his research on electricity in rarefied gases.
Between 1886 and 1889 Hertz published two papers on contact mechanics that would prove extremely important to the field of electrodynamics.
In 1887 he published his paper, "On Electromagnetic Effects Produced by Electrical Disturbances in Insulators."
Hertz discovered the photoelectric effect which states that a charged object loses its charge faster when exposed to ultraviolet light.
He did not realize the importance and practical implications of his experiments and did not foresee their eventual use in wireless communications.
In 1930 the hertz (Hz) was established as the name for frequency replacing the previous "cycles per second."
He died of Wegener's granulomatosis at the age of 36.
