Hillel Kook

Hillel Kook (Hebrew: הלל קוק; 24 July 1915 –18 August 2001), also known as Peter Bergson (Hebrew: פיטר ברגסון), was a Revisionist Zionist activist and politician.

Kook led the Irgun's efforts in the United States during World War II and the Holocaust in order to promote Zionism, attempting thereby to save the abandoned Jews of Europe. His rescue group's activism was the main factor leading to President Franklin D. Roosevelt establishing the War Refugee Board, which rescued as many as 200,000 European Jews, partly via the Wallenberg mission. He later served in Israel's first Knesset, but resigned in 1951 after becoming disillusioned with Israeli politics.
