Albert Einstein - German Physicist.

Albert Einstein ( 14 March 1879 – 18 April 1955) was a German-born theoretical physicist. Einstein's work is also known for its influence on the philosophy of science. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 Nobel Prize in Physics for his "services to theoretical physics", in particular his discovery of the law of the photoelectric effect, a pivotal step in the evolution of quantum theory.

Albert Einstein ( 14 March 1879 – 18 April 1955) was a German-born theoretical physicist. Einstein's work is also known for its influence on the philosophy of science. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 Nobel Prize in Physics for his "services to theoretical physics", in particular his discovery of the law of the photoelectric effect, a pivotal step in the evolution of quantum theory.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe.

He was visiting the United States when Adolf Hitler came to power in 1933 and, being Jewish, did not go back to Germany, where he had been a professor at the Berlin Academy of Sciences. He settled in the U.S., becoming an American citizen in 1940.[10] On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting him to the potential development of "extremely powerful bombs of a new type" and recommending that the U.S. begin similar research. This eventually led to what would become the Manhattan Project. Einstein supported defending the Allied forces, but largely denounced the idea of using the newly discovered nuclear fission as a weapon. Later, with the British philosopher Bertrand Russell, Einstein signed the Russell–Einstein Manifesto, which highlighted the danger of nuclear weapons. Einstein was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.

Einstein published more than 300 scientific papers along with over 150 non-scientific works. On 5 December 2014, universities and archives announced the release of Einstein's papers, comprising more than 30,000 unique documents. Einstein's intellectual achievements and originality have made the word "Einstein" synonymous with genius.

Adolf Hitler - Austrian-born German Politician

Adolf Hitler (German:; 20 April 1889 – 30 April 1945) was an Austrian-born German politician who was the leader of the Nazi Party (German: Nationalsozialistische Deutsche Arbeiterpartei (NSDAP); National Socialist German Workers Party). He was chancellor of Germany from 1933 to 1945 and dictator of Nazi Germany (as Führer und Reichskanzler) from 1934 to 1945. Hitler was at the centre of Nazi Germany, World War II in Europe, and the Holocaust.

Hitler was a decorated veteran of World War I. He joined the German Workers' Party (precursor of the NSDAP) in 1919, and became leader of the NSDAP in 1921. In 1923, he attempted a coup in Munich to seize power. The failed coup resulted in Hitler's imprisonment, during which time he wrote his memoir, Mein Kampf (My Struggle). After his release in 1924, Hitler gained popular support by attacking the Treaty of Versailles and promoting Pan-Germanism, antisemitism, and anti-communism with charismatic oratory and Nazi propaganda. Hitler frequently denounced international capitalism and communism as being part of a Jewish conspiracy.

Hitler's Nazi Party became the largest elected party in the German Reichstag, leading to his appointment as chancellor in 1933. Following fresh elections won by his coalition, the Reichstag passed the Enabling Act, which began the process of transforming the Weimar Republic into the Third Reich, a single-party dictatorship based on the totalitarian and autocratic ideology of National Socialism. Hitler aimed to eliminate Jews from Germany and establish a New Order to counter what he saw as the injustice of the post–World War I international order dominated by Britain and France. His first six years in power resulted in rapid economic recovery from the Great Depression, the denunciation of restrictions imposed on Germany after World War I, and the annexation of territories that were home to millions of ethnic Germans – actions which gave him significant popular support.

Hitler actively sought Lebensraum ("living space") for the German people. His aggressive foreign policy is considered to be the primary cause of the outbreak of World War II in Europe. He directed large-scale rearmament and on 1 September 1939 invaded Poland, resulting in British and French declarations of war on Germany. In June 1941, Hitler ordered an invasion of the Soviet Union. By the end of 1941 German forces and their European Allies occupied most of Europe and North Africa. Failure to defeat the Soviets and the entry of the United States into the war forced Germany onto the defensive and it suffered a series of escalating defeats. In the final days of the war, during the Battle of Berlin in 1945, Hitler married his long-time lover, Eva Braun. On 30 April 1945, less than two days later, the two committed suicide to avoid capture by the Red Army, and their corpses were burned.

Under Hitler's leadership and racially motivated ideology, the Nazi regime was responsible for the genocide of at least 5.5 million Jews and millions of other victims whom he and his followers deemed racially inferior. Hitler and the Nazi regime were also responsible for the killing of an estimated 19.3 million civilians and prisoners of war. In addition, 29 million soldiers and civilians died as a result of military action in the European Theatre of World War II. The number of civilians killed during the Second World War was unprecedented in the history of warfare.
