Shaul Nehamia Eisenberg (Hebrew: שאול אייזנברג; 1921–1997) was a Jewish businessmen and a billionaire tycoon.
Eisenberg was born in 1921 in Munich to a religious Jewish family from Poland. Shortly after the uprising of the Nazis in the government, he fled and wandered as a refugee around Europe.
He later moved to Japan. In 1941, he married a local woman. During World War II he worked with industrial factories, associating with the Axis Power countries. After the war ended, he began working with American businesses, importing iron products for the Japanese steel industry, when at the same time exporting a variety of Japanese-made products to India.
At the start of the 1950s, Eisenberg expanded his business to other countries in the Far East, especially South Korea, where he invested money while mediating between the local authority to manufacturers from the East that were also doing business there. Among them were: British Electric, Siemens, MAN SE, and Fiat Automobiles. Within a decade, he managed to mediate a vast variety of projects, such as developing production lines for recycled paper and purchasing airplanes and trains. He got an award from the Korean government for his actions. Until the mid-1960s, Eisenberg was the primary factor and catalyst in the commerce between South Korea and Japan to Western countries. He got high brokerage commissions, and therefore a few of which led to local and international scandals.
Eisenberg founded the company Israel Corporation, and a new law was enacted for him, allowing the company to have a tax break for 30 years. The law, which got its nickname from Eisenberg, was meant to encourage entrepreneurs. Upon getting these benefits, Eisenberg began mimicking his international actions and do them in Israel as well, which led him to settle in Savyon, Israel. With Israel Corporation he began purchasing some holdings in the companies Zim Integrated Shipping Services, Oil Refineries, and others.
