Arthur Ruppin

In 1907 Warburg (and Wolfsonn and Kann) convinces Ruppin to go to Palestine and head the soon to be founded Palestine Office. He arrives in Jaffa on May 7 1907.

In July 1907 one of the 60 families tells Ruppin they started Ahuzat Bayit to move out of Jaffa. Ruppin supports the idea and starts lobbying for a loan from JNF
