Jacob Henry Schiff was a German-born American banker, businessman, and philanthropist. He helped finance the expansion of American railroads, and the Japanese military efforts against Tsarist Russia in the Russo-Japanese War.

Kuhn, Loeb & Co. was an American multinational investment bank founded in 1867 by Abraham Kuhn and his brother-in-law Solomon Loeb. Under the leadership of Jacob H. Schiff, Loeb's son-in-law, it grew to be one of the most influential investment banks in the late 19th and early 20th centuries, financing America's expanding railways and growth companies, including Western Union and Westinghouse, and thereby becoming the principal rival of J.P. Morgan & Co.
