Who is Moskowitz?
subhead:
Millionaire investor, who acquires land and gives support to the right.

Since the 1970s, millionaire Irving Moskowitz has invested tens of millions of dollars in acquiring land in Jerusalem and in the Golan Heights area.

Moskowitz, 72, lives in Miami. He is the son of Polish immigrants. After he studied medicine, he acquired a small clinic that quickly turned into a prosperous private hospital. After his success, Moskowitz developed a series of hospitals and old age residences in the state Florida.

By the end of the 80s he received a permit to operate bingo parlors at the periphery of Los Angeles. According to the agreement with the California authorities, Moskowitz was supposed to use a portion of its earnings for charitable purposes. Nevertheless, various journalistic investigations suggest that the money was used for the acquiring of land in the territories and for the support of right-wing parties in Israel.

Moskowitz carried on a long-time relationship with former Prime Minister Benjamin Netanyahu that began when Moskowitz was involved with a foundation under the name of Netanyahu's brother, Yoni, of blessed memory. In September 1997, the relationship between the two of them became difficult when Netanyahu froze the building project in the neighborhood of Ras al-Amud in East Jerusalem. "I invested a lot of money in Netanyahu. I used my personal connections in order to further his career. I did not expect that he would act like this," Moskowitz was quoted as saying at the time.

Cherna Moskowitz: She is Irving's second wife and is involved in all of her husband's activities. The couple has eight sons and daughters. One of them lives in Israel.
