On this day in 1857 Heinrich Hertz was born in Hamburg, Germany. In the 1880s he performed experiments that confirmed James Clerk Maxwell's theory of electromagnetism. Hertz generated what are now called radio waves and showed that they behave just like heat and visible light—they are all varieties of electromagnetic radiation. The hertz (Hz) is now a unit of measurement denoting the frequency, or number of cycles per second, of light and sound waves, computer processors, and more.
