Hermann Broch (German: [bʀɔχ]; November 1, 1886 – May 30, 1951) was a 20th-century Austrian writer, considered one of the major Modernists.
Broch was born in Vienna to a prosperous Jewish family and worked for some time in his family's factory, though he maintained his literary interests privately. He was predestined to work in his father’s textile factory in Teesdorf, therefore, he attended a technical college for textile manufacture and a spinning and weaving college.
In 1909 he converted to Roman Catholicism and married Franziska von Rothermann, the daughter of a knighted manufacturer. The following year, their son Hermann Friedrich Maria was born. Later, Broch began to see other women and the marriage ended in divorce in 1923.
He was acquainted with Robert Musil, Rainer Maria Rilke, Elias Canetti, Leo Perutz, Franz Blei and his devoted friend and inspiration, writer and former nude model Ea von Allesch and many others. In 1927 he sold the textile factory and decided to study mathematics, philosophy and psychology at the University of Vienna. He embarked on a full-time literary career only around the age of 40. At the age of 45, his first novel, The Sleepwalkers was published by Daniel Brody, Publisher of the Rhein Verlag in 1931/1932 in Munich.
