A Man Without a Country (subtitle: "A Memoir Of Life In George W Bush's America") is an essay collection published in 2005 by the author Kurt Vonnegut.
 The extremely short essays that make up this book deal with topics ranging from the importance of humor, to problems with modern technology, to Vonnegut's opinions on the differences between men and women.
 Most prevalent in the text, however, are those essays that elucidate Vonnegut's opinions on politics, and the issues in modern American society, often from a decidedly humanistic perspective.
 In January 2007, Vonnegut indicated that he intended this to be his final work, a statement that proved to be correct with his death in April 2007.
 Later published works of Vonnegut's were all published posthumously, and consisted almost entirely of previously unpublished material from early in his career.
Clemens Vonnegut Sr. (November 20, 1824 – December 13, 1906) was a German emigrant to the United States and successful businessman.
 He was the patriarch of the prominent German-American Vonnegut clan (later Schnull-Vonnegut) of Indiana – he was the father and grandfather of architects Bernard Vonnegut I and Kurt Vonnegut Sr., respectively, and great-grandfather of scientist Bernard Vonnegut and author Kurt Vonnegut Jr.
Slaughterhouse-Five, or The Children's Crusade: A Duty-Dance with Death (1969) is a satirical novel by Kurt Vonnegut about the World War II experiences and journeys through time of Billy Pilgrim, from his time as an American soldier and chaplain's assistant, to postwar and early years.
 It is generally recognized as Vonnegut's most influential and popular work.
 A central event is Pilgrim's surviving the Allies' firebombing of Dresden as a prisoner-of-war.
 This was an event in Vonnegut's own life, and the novel is considered semi-autobiographical.
"Breakfast of Champions, or Goodbye Blue Monday," published in 1973, is the seventh novel by the American author Kurt Vonnegut.
 Set predominantly in the fictional town of Midland City, Indiana, it is the story of "two lonesome, skinny, fairly old white men on a planet which was dying fast."
 One of these men, Dwayne Hoover, is a charming but deeply deranged Pontiac dealer, and extensive land and franchise owner, whose mental illness causes him to believe that a science fiction story by the other man, Kilgore Trout, is the literal truth.
 Trout, a largely unknown pulp science fiction writer who has appeared in several other Vonnegut novels, looks like a crazy old man but is in fact relatively sane.
 As the novel opens, Trout hitchhikes toward Midland City to appear at an art convention where he is destined to meet Dwayne Hoover and unwittingly inspire him to run amok.

 He designed several churches, banks, and became the inhouse architect for Indiana Bell and Hooks Drug stores (prior to World War II), practicing extensively in the Art Deco style.
 He was the father of chemist Bernard Vonnegut and author Kurt Vonnegut Jr.
