Across the world, הרץ (Hertz , Herz , הרץ ) is a rare principally masculine, but scarcely feminine first name. The given name הרץ is habitual in Israel, where it is quite a rare boy's name, Austria, where it is a rare male name, and Philippines, where it is a very rare dominantly male, but infrequently female name. Not in comparison with a country's population, it is the most numerous in Indonesia, Israel, and Brazil. More prevalently, הרץ is the last name as well as the forename.
הרץ is also a name for the fictitious and mythical characters: Herz , the operatic character in the opera Eis und Stahl, Ice and steel; Hertz , the musical character in the musical Rock of Ages and Herz , the operatic character in the opera Der Schauspieldirektor by Wolfgang Amadeus Mozart; an actor.
