Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by German engineer Konrad Zuse in 1939, was one of the earliest examples of an electromechanical relay computer.
When Hitler and his army chiefs asked for a pretext for the invasion of Poland in 1939, Himmler, Heydrich, and Heinrich Müller masterminded and carried out a false flag project code-named Operation Himmler. German soldiers dressed in Polish uniforms undertook border skirmishes which deceptively suggested Polish aggression against Germany. The incidents were then used in Nazi propaganda to justify the invasion of Poland, the opening event of World War II.
In 1939 that marked the transition in Nazi racial antisemitism toward genocide. To justify the murder of the Jews both to the perpetrators and to bystanders in Germany and Europe, the Nazis used not only racist arguments but also arguments derived from older negative stereotypes, including Jews as communist subversives, as war profiteers and hoarders, and as a danger to internal security because of their inherent disloyalty and opposition to Germany.
The German army, the Wehrmacht, was accompanied by seven SS Einsatzgruppen ("special task forces") and an Einsatzkommando, numbering altogether 3,000 men, whose role was to deal with "all anti-German elements in the hostile country behind the troops in combat". Most of the Einsatzgruppen commanders were professionals; 15 of the 25 leaders had PhDs.
On 29 August, Hitler demanded that a Polish plenipotentiary immediately travel to Berlin to negotiate the handover of Danzig, and to allow a plebiscite in the Polish Corridor in which the German minority would vote on secession.
In 1939 Kennedy toured Europe, the Soviet Union, the Balkans, and the Middle East in preparation for his Harvard senior honors thesis. He then went to Czechoslovakia and Germany before returning to London on September 1, 1939, the day that Germany invaded Polandto mark the beginning of World War II.
On 2 September 1939 (the day after the start of the war), Goebbels and the Council of Ministers proclaimed it illegal to listen to foreign radio stations. Disseminating news from foreign broadcasts could result in the death penalty.
The German Volksgrenadier units each had a battalion of bicycle infantry attached. The Invasion of Poland saw many bicycle-riding scouts in use, with each bicycle company using 196 bicycles and 1 motorcycle. By September 1939, there were 41 bicycle companies mobilized.
According to a letter dated 21 September 1939 from SS-Obergruppenführer Reinhard Heydrich, head of the Reichssicherheitshauptamt (RSHA or Reich Security Head Office), to the Einsatzgruppen, each ghetto had to be run by a Judenrat, or "Jewish Council of Elders", to consist of 24 male Jews with local influence.
On 6 October, Hitler made a public peace overture to the United Kingdom and France but said that the future of Poland was to be determined exclusively by Germany and the Soviet Union. The proposal was rejected, and Hitler ordered an immediate offensive against France, which would be postponed until the spring of 1940 due to bad weather.
In October 1939 Hitler signed a "euthanasia decree" backdated to 1 September 1939 that authorized Reichsleiter Philipp Bouhler, the chief of Hitler's Chancellery, and Karl Brandt, Hitler's personal physician, to carry out a program of involuntary euthanasia. After the war this program came to be known as Aktion T4, named after Tiergartenstraße 4, the address of a villa in the Berlin borough of Tiergarten, where the various organizations involved were headquartered.
