Arthur Ruppin (1876-1943) was the chief “doer” of the Zionist Movement in Palestine. He was placed in charge of executing the practical necessities of developing Jewish settlement. Working with the Jewish National Fund he became the Yishuv’s main buyer of land. He believed that the most essential element in the creation of a Jewish state then was to buy land and settle it as quickly as possible by any means possible. He created two of Israel’s most famous and lasting institutions: Tel Aviv and the kibbutz.
