Jacob Schiff arrived in New York in 1865. Ten years later he became the partner of the Illuminati firm Kuhn, Loeb & Company. Ten years after that he became Its president. Directing Rothschild and Illuminati affairs from this seat of authority. Jacob Schiff was also on the board of directors of Central Trust Company, Western Union. and Wells Fargo Company.
