• Heinrich Hertz was an inventor.• James Clerk Maxwell, an English physicist, formulated the

electromagnetic theory.• Numerous people have tried the prove the theory, and Hertz

was the first to do it.• “Hertz proved that electricity travels in waves at the speed of

light and that these waves possessed many of the same properties of light waves themselves. Between 1885 and 1889, Hertz was the first person to broadcast radio waves and also prove that light was a form of electromagnetic radiation.” from http://www.funtrivia.com/en/subtopics/Oh-That-Hertz-154977.html

Impacts on the World• Heinrich Hertz made it possible for later inventors to make radios,

televisions, cell phones, and numerous other objects that require electricity.

• Scientific names such as the frequency unit and the SI unit; hertz (Hz), kilohertz (kHz), and megahertz (MHz) were named after Heinrich Hertz.

• A crater on the moon was named in his honor.• In Japan, he is honored by being a member in the Order of the Scared

Treasure.• His picture has appeared on many countries’ post stamps. Especially

in German during World War II.• On February 22, 2012 (Hertz’s birthday in 2012, Google made a

Google Doodle about his life’s work for him.
