Fritz Fischer (5 March 1908 – 1 December 1999) was a German historian best known for his analysis of the causes of World War I.
 In the early 1960s Fischer put forward the controversial thesis that responsibility for the outbreak of the war rested solely on Imperial Germany.
 He has been described by "The Encyclopedia of Historians and Historical Writing" as the most important German historian of the 20th century.
War of Illusions: German policies from 1911 to 1914 is a book by German historian Fritz Fischer, first published in German in 1969 as "Krieg der Illusionen".
Germany's Aims in the First World War (German title: Griff nach der Weltmacht: Die Kriegzielpolitik des kaiserlichen Deutschland 1914–1918) is a book by German Historian Fritz Fischer.
 It is one of the leading contributions to historical analysis of the Causes of World War I, and along with this work "War of Illusions" "(Krieg der Illusionen)" gave rise to the "Fischer Thesis" on the causes of the war.
 The title translates as "Grab for World Power".
 or "Bid for World Power".
 Essentially Fischer attempts to link together a continuum of German belligerence in their "grab for power" weaving it all together into a cohesive theme of German "Weltpolitik".
Sven Fischer (born 16 April 1971) is a former German biathlete.
 He trained with the WSV Oberhof 05 club, and was coached by Frank Ullrich and Fritz Fischer (national coaches) and Klaus Siebert (club coach).
 After the 2006/07 biathlon season, he retired.
Nazi human experimentation was a series of medical experiments on large numbers of prisoners, including children, by Nazi Germany in its concentration camps in the early to mid 1940s, during World War II and the Holocaust.
 Chief target populations included Romani, Sinti, ethnic Poles, Soviet POWs, disabled Germans, and most prominently of all, Jews from across Europe.
Historians writing about the origins of World War I have differed over the relative emphasis they place upon the factors involved.
 Changes in historical arguments over time are in part related to the delayed availability of classified historical archives.
 The deepest distinction among historians remains between those who focus on the actions of Germany and Austria-Hungary as key and those who focus on a wider group of actors.
 Those historians such as Fritz Fischer who believe that Germany deliberately planned a European war, once a widespread view, are now in a small minority.
 The main distinction is now between those who believe that a war between the "Great Powers" was ultimately unplanned but still caused principally by Germany and Austria-Hungary taking risks, and those who believe that either all or some of the other powers, namely Russia, France, Serbia and Great Britain, played a more significant role in risking war than had been traditionally suggested.
The Escape to Nice (German:Flucht nach Nizza) is a 1932 German comedy crime film directed by James Bauer and starring Fritz Fischer, Georg Alexander and Else Elster.
 The film is based on the novel "Orje Lehmann wird Detektiv" by Dolly Bruck (Hans Mahner-Mons).
 It premiered on 14 June 1932.
