There are many ways to describe Leo Perutz: novelist, mathematician, native of Prague, chess lover—to name but a few. He was admired by his colleagues and millions of readers. His success as a writer was so great that he decided in 1923 to give up his bread-and-butter job as an actuary. The Great Depression hit him hard, since the crisis not only negatively impacted the bookselling trade but also rendered the family company, in which he had a share, less profitable. To make matters worse, after the Nazis’ rise to power, his Jewish publisher, Paul Szolnay, lost his largest market in Germany. This is one of the last photographs taken before Perutz’s emigration from Vienna to Tel Aviv, Palestine in 1938.
