Luiz Heinrich Mann, best known as simply Heinrich Mann, was a German writer renowned for his socio-political novels. From 1930 until 1933, he served as the president of the fine poetry division of the Prussian Academy of Arts. His fierce criticism of the rising Fascism and Nazism compelled him to flee Germany after the Nazis ascended to power in 1933. He was the elder brother of the famed writer Thomas Mann.

Born in Lübeck as the eldest child of Thomas Johann Heinrich Mann and Júlia da Silva Bruhns, Heinrich was part of a patrician grain merchant family. His father was a Senator of the Hanseatic city. Following his father's death, his mother relocated the family to Munich, where Heinrich embarked on his career as a freier Schriftsteller or free novelist.
