David Ben-Gurion, Polish-Israeli lawyer and politician, 1st Prime Minister of Israel (b. 1886)
David Ben-Gurion ( ben GOOR-ee-ən; Hebrew: דָּוִד בֶּן-גּוּרִיּוֹן [daˈvid ben ɡuʁˈjon] (listen); born David Grün; 16 October 1886 – 1 December 1973) was the primary national founder of the State of Israel and the first Prime Minister of Israel. Adopting the name of Ben-Gurion in 1909, he rose to become the preeminent leader of the Jewish community in British-ruled Mandatory Palestine from 1935 until the establishment of the State of Israel in 1948, which he led until 1963 with a short break in 1954–55.

Ben-Gurion's passion for Zionism, which began early in life, led him to become a major Zionist leader and executive head of the World Zionist Organization in 1946. As head of the Jewish Agency from 1935, and later president of the Jewish Agency Executive, he was the de facto leader of the Jewish community in Palestine, and largely led its struggle for an independent Jewish state in Mandatory Palestine. On 14 May 1948, he formally proclaimed the establishment of the State of Israel, and was the first to sign the Israeli Declaration of Independence, which he had helped to write. Ben-Gurion led Israel during the 1948 Arab–Israeli War, and united the various Jewish militias into the Israel Defense Forces (IDF). Subsequently, he became known as "Israel's founding father".Following the war, Ben-Gurion served as Israel's first prime minister and minister of defense. As prime minister, he helped build the state institutions, presiding over national projects aimed at the development of the country. He also oversaw the absorption of vast numbers of Jews from all over the world. A centerpiece of his foreign policy was improving relationships with the West Germans. He worked with Konrad Adenauer's government in Bonn, and West Germany provided large sums (in the Reparations Agreement between Israel and West Germany) in compensation for Nazi Germany's confiscation of Jewish property during the Holocaust.In 1954 he resigned as prime minister and minister of defense but remained a member of the Knesset. He returned as minister of defense in 1955 after the Lavon Affair and the resignation of Pinhas Lavon. Later that year he became prime minister again, following the 1955 elections. Under his leadership, Israel responded aggressively to Arab guerrilla attacks, and in 1956, invaded Egypt along with British and French forces after Egypt nationalized the Suez Canal during the Suez Crisis.

He stepped down from office in 1963, and retired from political life in 1970. He then moved to Sde Boker, a kibbutz in the Negev desert, where he lived until his death. Posthumously, Ben-Gurion was named one of Time magazine's 100 Most Important People of the 20th century.
