Heinrich Hertz (1857–1894) was a German physicist who made significant contributions to the field of electromagnetism. He is best known for his experiments that confirmed James Clerk Maxwell's theories about electromagnetic waves. Hertz was the first to produce and detect these waves in the laboratory, demonstrating that they could travel through space and confirming that they behave similarly to light waves. The unit of frequency, the "hertz" (Hz), is named in his honor.
