Kleber is a name of German origin, derived from the word 'clever'. It was popularized by French writer Jean-François Champollion, who named his younger brother Kleber after Kleber, one of Napoleon's generals. The name gained further recognition through Jean-Baptiste Kléber, a French general during the French Revolutionary Wars and the Napoleonic Wars. In Portuguese-speaking countries like Brazil, Kleber is often used as a given name, with 'Klebinho' being a familiar or diminutive form.
