A) Indira Priyadarshini Gandhi (1917-1984)

Famous people of the XX century

Indira Priyadarshini Gandhi was an Indian politician who served as the third Prime Minister of India for three consecutive terms (1966–77) and a fourth term (1980–84). Gandhi was the second female head of government in the world after Sirimavo Bandaranaike of Sri Lanka, and she remains as the world's second longest serving female Prime Minister as of 2012. She was the first woman to become prime minister in India.

Gandhi was the only child of Jawaharlal Nehru, the first prime minister of independent India. She adhered to the quasi-socialist policies of industrial development that had been begun by her father. Gandhi established closer relations with the Soviet Union, depending on that nation for support in India's long-standing conflict with Pakistan. She was also the only Indian Prime Minister to have declared a state of emergency in order to 'rule by decree' and the only Indian Prime Minister to have been imprisoned after holding that office. She was assassinated by her Sikh bodyguards in retaliation for ordering Operation Blue Star. http://en.wikipedia.org/wiki/ Indira Gandhi

Albert Einstein was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics and one of the most prolific intellects in human history. While best known for his mass–energy equivalence formula E = mc2, he received the 1921 Nobel Prize in Physics.

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 theory of 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 structure of the universe as a whole.

He was visiting the United States when Adolf Hitler came to power in 1933, and 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 a citizen in 1940. On the eve of World War II, he helped alert President Franklin D. Roosevelt that Germany might be developing an atomic weapon, and recommended that the U.S. begin similar research; this eventually led to what would become the Manhattan Project. Einstein was in support of defending the Allied forces, but largely denounced using the new discovery of nuclear fission as a weapon. Later, together with 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.
