Now and Then: From Coney Island to Here: Now and Then is Joseph Heller's 1998 memoir.  The first half of the memoir focuses on Heller's childhood in Coney Island and is, in fact, as much about the place as it is about the man.  Heller describes growing up, his mother and half-siblings in a fundamentally safe and fun neighborhood of punch ball, football, amusement park, and Nathan's Famous Hot Dog Stand.

Franz Conrad von Hötzendorf: "K.u.k. Feldmarschall" Franz Xaver Joseph Conrad Graf von Hötzendorf German: "Franz Xaver Josef Graf Conrad von Hötzendorf" (11 November 1852 – 25 August 1925), sometimes anglicised as Hoetzendorf, was an Austrian Field Marshal and Chief of the General Staff of the armed forces of the Austro-Hungarian Army and Navy 1906–1917.  He was the Empire's chief of staff during the 1914 July Crisis that led to the outbreak of World War I.  He argued persuasively for preventive war against Serbia, saying it was needed to hold together his polyglot empire on the verge of breaking down.  He later decided that Austria acted too late, and its failure to fight earlier was a fatal mistake.  He admitted his army was not ready for war, and therefore emphasized the political necessity.  He failed to realize that Germany would force him to put his chief assets on the Russian front, rather than Serbia.  Conrad was fearful of attacking Russia and when Russia nearly broke through the Carpathian mountains and Conrad's Carpathian Offensive failed Italy entered the war thinking the Empire was collapsing.  It was not a good time however as Germany helped Austria break through Russia and the taking of Serbia so Conrad shifted his attention away from the Balkans toward Italy and Russia.  From early 1915 his forces were increasingly dependent on German support and command.  Without German support the Austrian army was a spent force.

Under Western Eyes (novel): Under Western Eyes (1911) is a novel by Joseph Conrad.  The novel takes place in St. Petersburg, Russia, and Geneva, Switzerland, and is viewed as Conrad's response to the themes explored in "Crime and Punishment"; Conrad was reputed to have detested Dostoevsky.  It is also, some say, Conrad's response to his own early life; his father was a famous revolutionary imprisoned by the Russians, but, instead of following in his father's footsteps, at the age of sixteen Conrad left his native land forever.  Indeed, while writing "Under Western Eyes", Conrad suffered a weeks-long breakdown during which he conversed with the novel's characters in Polish.

Catch-22 (film): Catch-22 is a 1970 American black comedy war film adapted from the novel of the same name by Joseph Heller.

Joseph Conrad: Joseph Conrad (] ; born Józef Teodor Konrad Korzeniowski; 3 December 1857 – 3 August 1924) was a Polish-British writer regarded as one of the greatest novelists to write in the English language.  He joined the British merchant marine in 1878, and was granted British nationality in 1886.  Though he did not speak English fluently until his twenties, he was a master prose stylist who brought a non-English sensibility into English literature.  He wrote stories and novels, many with a nautical setting, that depict trials of the human spirit in the midst of an impassive, inscrutable universe.
