Cid (Sidney) Corman (June 29, 1924 – March 12, 2004) was an American poet, translator and editor, most notably of "Origin", who was a key figure in the history of American poetry in the second half of the 20th century.
Joseph Roth, born Moses Joseph Roth (2 September 1894 – 27 May 1939), was an Austrian-Jewish journalist and novelist, best known for his family saga "Radetzky March" (1932), about the decline and fall of the Austro-Hungarian Empire, his novel of Jewish life, "Job" (1930), and his seminal essay "Juden auf Wanderschaft" (1927; translated into English in "The Wandering Jews"), a fragmented account of the Jewish migrations from eastern to western Europe in the aftermath of World War I and the Russian Revolution.
 In the 21st century, publications in English of "Radetzky March" and of collections of his journalism from Berlin and Paris created a revival of interest in Roth.
The Wandering Jews is a short non-fiction book (1926–27) by Joseph Roth about the plight of the Jews in the mid-1920s who, with other refugees and displaced persons in the aftermath of the First World War, the Russian Revolution and the redrawing of national frontiers following the Treaty of Versailles, had fled to the West from the Baltic States, Poland and Russia.
 "They sought shelter in cities and towns where most of them had never been and , unfortunately, where they were made despicably unwelcome."
 Poverty stricken villagers, they were set apart by their origins, their piety and their dress.
 In the last five months of 1926 he visited the Soviet Union where he wrote the final section, "The Condition of the Jews in Soviet Russia".
 Walter Jens called it the best book on its subject in German.
 An English translation by Michael Hofmann was published in 2001.
Origin was an American poetry magazine that was founded in 1951 by Cid Corman.
 The magazine provided an early platform for the work of Charles Olson, Robert Creeley, Gary Snyder, Theodore Enslin and other important, ground-breaking poets, who collectively created an alternative to academic poetry.
Theodore Vernon Enslin (born March 25, 1925 – November 21, 2011) was an American poet associated with Cid Corman's "Origin" and press.
 He is widely regarded as one of the most musical of American avant-garde poets.
Verlag Die Schmiede was an avant-garde literature publishing house in the 1920s in Berlin.
 It published works by Franz Kafka, Alfred Döblin, Joseph Roth, Rudolf Leonhard, and many more.
 Most of its dust jackets have been designed by George Salter, the later US citizen.
Spider's Web: A Pig's Tale (German: "Das Spinnennetz" ) is a 1989 West German film directed by Bernhard Wicki.
 It is based on the eponymous 1923 novel by Joseph Roth.
 It was chosen as West Germany's official submission to the 62nd Academy Awards for Best Foreign Language Film, but did not manage to receive a nomination.
 The film was the last ever submission by West Germany, due to German reunification in 1990, Germany competed at the 63rd Academy Awards as a single country.
The opera is based on Joseph Roth's novel, "Job - The Story of a Simple Man", itself inspired by the biblical "Book of Job".
 In July 1939, a dramatization of the novel was arranged in Paris in honour of Roth (who had died in May 1939) and Zeisl, who had recently arrived in Paris in flight from Nazi Germany, wrote some incidental music for this production.
 This inspired him to create a complete opera based on Roth's work, for which he persuaded his friend Hans Kafka (1902—1974) to write a libretto.
 Zeisl composed the first act by 1940, by which time he was now living in New York.
 Kafka was not able to produce the libretto for Act II until 1957.
 Zeisl completed the composition of this, but died in 1959.
Radetzky March (German: "Radetzkymarsch" ) is a 1932 novel by Joseph Roth chronicling the decline and fall of the Austro-Hungarian Empire via the story of the Trotta family.
 "Radetzkymarsch" is an early example of a story that features the recurring participation of a historical figure, in this case the Emperor Franz Joseph I of Austria (1830–1916).
 Roth continues his account of the Trotta family to the time of the Anschluss in his "The Emperor's Tomb" ("Kapuzinergruft", 1938).
 The novel was published in English translation in 1933, and in a new, more literal, translation in 1995.
What I Saw: Reports from Berlin, 1920-1933 is a book of reportage by the Austrian writer Joseph Roth from the era of the Weimar Republic.
 The selection of pieces from Roth's large journalistic output was made by Michael Bienert and published in German in 1996.
 The English translation with the present title was made by Michael Hofmann and appeared in 2003.
