Google Doodle – Happy Birthday Heinrich Hertz


The Google Doodle today is in honour of Heinrich Hertz, who would have been celebrating his 155th birthday  – if he hadn’t died from Wegener’s granulomatosis in 1894, or something else since then.

Hertz was the first to conclusively prove the existence of electromagnetic waves.


In 1930, the Hertz was made the SI unit of frequency which measures the number of cycles per second of a periodic phenomenon.

Google frequently replaces its familiar Goooogle logo with a special design to commemorate special days. It has used animated images such as the Hertz logo only rarely.

Happy birthday, Heinrich.
