Heinrich Mann was a German novelist and essayist born on March 27, 1871, in Lübeck, Germany. He was part of the Mann family, a prominent literary family that included his brother, Thomas Mann, who won the Nobel Prize in Literature. Heinrich's works often explored themes of social criticism and individual freedom, reflecting his opposition to authoritarianism. Mann's most famous novel, The Loyal Subject, critiques the nature of power and loyalty in society. Throughout his life, he was an outspoken critic of German nationalism and the rise of Nazism, which led him to emigrate to the United States in 1933. He continued to write until his death on March 11, 1950.
