Mayor of Jerusalem for 28 years (1965 to 1993) and founder of the Jerusalem Foundation. During his tenure, Jerusalem developed into a modern city, especially after its reunification in 1967. He was once called “the greatest builder of Jerusalem since Herod.”
In 1935 the Kollek family immigrated to Palestine, then under British mandate. In 1937, he was one of the founders of Kibbutz Ein Gev, on the shore of Lake Kinneret.
In the 1940s, on behalf of the Jewish Agency and as part of the “The Hunting Season” or “Saison” Teddy Kollek was the Jewish Agency’s contact person with the British Mandate MI5, providing information against right-wing Jewish underground groups Irgun and Lehi (known as “Stern Gang”). In 1942 Kolleck was appointed the Jewish Agency’s deputy head of intelligence. Between January 1945 and May 1946 he was the Agency’s chief external liaison officer in Jerusalem and was in contact with MI5’s main representative as well as members of British Military Intelligence. During World War II, Kollek tried to represent Jewish interests in Europe on behalf of the Jewish Agency. In 1947–48, he represented the Haganah in Washington, where he assisted in acquiring ammunition for Israel’s then-fledgling army. Kollek became a close ally of David Ben-Gurion, serving in the latter’s governments from 1952 as the director general of the prime minister’s office.
Kollek was re-elected five times, in 1969, 1973, 1978, 1983, and 1989, serving 28 years as mayor of Jerusalem. In a reluctant seventh bid for mayor in 1993, Kollek, aged 82, lost to Likud candidate Ehud Olmert.
He died 2 January 2007.
