Google Doodles Birthday wave for Heinrich Rudolf Hertz’s


Today Google posted electromagnetic wave on home page to celebrate the 155th birthday of Heinrich Rudolf Hertz’s.Heinrich Rudolf Hertz (February 22, 1857 – January 1, 1894) was a German physicist who clarified and expanded the electromagnetic theory of light that had been put forth by Maxwell. He was the first to satisfactorily demonstrate the existence of electromagnetic waves by building an apparatus to produce and detect radio waves.

Hertz was born in Hamburg, then a sovereign state of the German Confederation, into a prosperous and cultured Hanseatic family. Hertz’s studied PhD in university of Berlin at the age of 22 and he become the professor at University of Karlsruhe in 1985; after becoming professor he discovered electromagnetic waves.

In 1892, an infection was diagnosed (after a bout of severe migraines) and Hertz underwent some operations to correct the illness. He died of Wegener’s granulomatosis at the age of 36 in Bonn, Germany in 1894, and was buried in Ohlsdorf, Hamburg at the Jewish cemetery.

The SI unit hertz (Hz) was established in his honor by the IEC in 1930 for frequency, a measurement of the number of times that a repeated event occurs per second. His name later became the term used for radio and electrical frequencies, as in hertz (Hz), kilohertz (kHz) and megahertz (MHz) etc.

The first Google Doodle was created by Larry Page and Sergey Brin Google in the year 1998 to mark the celebrations of the Burning Man Festival. Google currently has more than 1000 Doodles. Google recently announced the revamp of its Doodle site ( which houses all Google doodles since the very first back in 1998.
