“I use ‘disruptive’ in both its good and bad connotations. Disruptive scientific and technological progress is not to me inherently good or inherently evil. But its arc is for us to shape. Technology’s progress is furthermore in my judgment unstoppable. But it is quite incorrect that it unfolds inexorably according to its own internal logic and the laws of nature.”
In English and other languages, the term had been used since the 1920s.[4] The British press used it to describe the German successes in Poland in September 1939, called by Harris "a piece of journalistic sensationalism – a buzz-word with which to label the spectacular early successes of the Germans in the Second World War". It was later applied to the bombing of Britain, particularly London, hence "The Blitz".[22] The German popular press followed suit nine months later, after the fall of France in 1940; hence although the word had been used in German, it was first popularized by British journalism.[5][8] Heinz Guderian referred to it as a word coined by the Allies: "as a result of the successes of our rapid campaigns our enemies ... coined the word Blitzkrieg".[23] After the German failure in the Soviet Union in 1941, use of the term began to be frowned upon in the Third Reich, and Hitler then denied ever using the term, saying in a speech in November 1941, "I have never used the word Blitzkrieg, because it is a very silly word".[24] In early January 1942, Hitler dismissed it as "Italian phraseology".[25][26]
All of the musicians were required to perform forced labour in addition to their daily concerts.  They were also subject to regular selections.  As was the case in other camps, the musicians were required to play marches at the main gate when the work commandos left the camp in the morning and returned in the evening.  Due to the forced labour, frequent selections, suicides and generally poor health of the musicians, by the end of the year the orchestra was shrinking rather than growing.  Simultaneously, the sub-camp commander Johann Schwarzhuber, who provided the men with instruments and sheet music, increased his demands, seriously challenging Kopka's abilities.  The latter became increasingly dependent on the arranging and conducting skills of Laks, who grew skilled at composing music with interchangeable parts in case of the sudden disappearance of a musician.  Eventually Laks became the de facto conductor, a position made official when Kopka was sent to the front with the German army.
The Warsaw Ghetto Uprising was the largest ghetto revolt. Massive deportations (or Aktions) had been held in the ghetto from July to September 1942, emptying the ghetto of the majority of Jews imprisoned there. When the Germans entered the ghetto again in January 1943 to remove several thousand more, small unorganized groups of Jews attacked them. After four days, the Germans withdrew from the ghetto, having deported far fewer people than they had intended. The Nazis reentered the ghetto on April 19, 1943, the eve of Passover, to evacuate the remaining Jews and close the ghetto. The Jews, using homemade bombs and stolen or bartered weapons, resisted and withstood the Germans for 27 days. They fought from bunkers and sewers and evaded capture until the Germans burned the ghetto building by building. By May 16 the ghetto was in ruins and the uprising crushed.
The 15 men present at Wannsee included Adolf Eichmann (head of Jewish affairs for the RSHA and the man who organized the deportation of Jews), Heinrich Müller (head of the Gestapo), and other party leaders and department heads.[256] Thirty copies of the minutes were made. Copy no. 16 was found by American prosecutors in March 1947 in a German Foreign Office folder.[263] Written by Eichmann and stamped "Top Secret", the minutes were written in "euphemistic language" on Heydrich's instructions, according to Eichmann's later testimony.[264] The conference had several purposes. Discussing plans for a "final solution to the Jewish question" ("Endlösung der Judenfrage"), and a "final solution to the Jewish question in Europe" ("Endlösung der europäischen Judenfrage"),[256] it was intended to share information and responsibility, coordinate efforts and policies ("Parallelisierung der Linienführung"), and ensure that authority rested with Heydrich. There was also discussion about whether to include the German Mischlinge (half-Jews).[265] Heydrich told the meeting: "Another possible solution of the problem has now taken the place of emigration, i.e. the evacuation of the Jews to the East, provided that the Fuehrer gives the appropriate approval in advance."[256] He continued:
The last part of an offensive operation was the destruction of un-subdued pockets of resistance, which had been enveloped earlier and by-passed by the fast-moving armoured and motorised spearheads. The Kesselschlacht 'cauldron battle' was a concentric attack on such pockets. It was here that most losses were inflicted upon the enemy, primarily through the mass capture of prisoners and weapons. During Operation Barbarossa, huge encirclements in 1941 produced nearly 3.5 million Soviet prisoners, along with masses of equipment.[66][f]
Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.
