Heinrich Rudolf Hertz (22 February 1857 – 1 January 1894) was a German physicist who clarified and expanded James Clerk Maxwell's electromagnetic theory of light, which was first demonstrated by David Edward Hughes using non-rigorous trial and error procedures. Hertz is distinguished from Maxwell and Hughes because he was the first to conclusively prove the existence of electromagnetic waves by engineering instruments to transmit and receive radio pulses using experimental procedures that ruled out all other known wireless phenomena. The scientific unit of frequency — cycles per second — was named the "hertz" in his honor.
海因里希·魯道夫·赫茲（Heinrich Rudolf Hertz，1857年2月22日－1894年1月1日），德國物理學家，於1887年首先用實驗證實了電磁波的存在，並於1888年發表了論文。他對電磁學有很大的貢獻，故頻率的國際單位制單位赫茲以他的名字命名。
