Mann was widely lauded as the greatest 20th-century German novelist; Heinrich was his brother, Klaus his son. Hesse was a friend from 1904, and Toller from WWI days. Mann drew extensively upon his friend Adorno’s musical knowledge, and greatly respected Musil, who however distrusted Mann. Wedekind and he knew each other well in Munich; Grosz found him full of himself in New York. Neighbours in exile included Einstein and Broch in Princeton, and Schoenberg, Brecht and Döblin in L.A. (the first fell out with him, the other two had never hidden their dislike). Freud wrote as a friend on Mann’s 60th birthday.
