Navon joined the bank of Johannes Frutiger from Switzerland, and promoted several important projects in Ottoman Palestine. In 1878, Navon and his uncle, Haim Amzallag, helped purchase the ground for the construction of
Petah Tikva, as well as
Rishon LeZion in 1882. They also built homes for new immigrants from
Yemen and the poor in
Jerusalem, creating demand in the lands which the bank owned. Together with Frutiger and Shalom Konstrum, Navon helped found the neighborhood of
Mahane Yehuda in 1887 with 162 houses. The neighborhood was named after Navon's brother Yehuda. By the time Navon accumulated sufficient personal wealth, he had a number of projects in mind: a new port in Palestine, electricity and water supply projects in Jerusalem, and a railway to the city. After the railway construction was completed, Navon set out to pursue some of the other projects, for which he had already acquired permits. However, the profits from the railway were not sufficient to finance these, and in 1894 Navon set out to
Paris, likely to look for investors. He never returned to Jerusalem, and after a 1901 meeting with
Theodor Herzl about development in the Yishuv, which the latter was not impressed with, Navon stopped his activity in the region. He spent the remainder of his days living off his title of "Bey" at the Ritz Hotel in Paris. He died in France in 1934. ==Biographies==
