Jacob Henry Schiff (born Jakob Heinrich Schiff; January 10, 1847 – September 25, 1920) was a German Confederation-born American banker, businessman, and philanthropist. Among many other things, he helped finance the expansion of American railroads, and the Japanese military efforts against Tsarist Russia in the Russo-Japanese War. Born in Frankfurt, Germany, Schiff migrated to the United States after the American Civil War and joined the firm Kuhn, Loeb & Co. From his base on Wall Street, he was the foremost Jewish leader from 1880 to 1920 in what later became known as the "Schiff era", grappling with all major Jewish issues and problems of the day, including the plight of Russian Jews under the Tsar, American and international antisemitism, care of needy Jewish immigrants, and the rise of Zionism. He also became a director of many important corporations, including the National City Bank of New York, Equitable Life Assurance Society, Wells Fargo & Company, and the Union Pacific Railroad. In many of his interests he was associated with E. H. Harriman. Schiff was born in 1847 in the Judengasse in Frankfurt am Main, Germany, to Moses and Clara (née Niederhofheim) Schiff, members of a distinguished Ashkenazi Jewish rabbinical family that traced its lineage in Frankfurt back to 1370. One ancestor, David Tevele Schiff, became lead rabbi in Great Britain and from 1765 until his death was acting head of the London Synagogue. Meir Ben Jacob Schiff, another relative, had become renowned as a Talmudic scholar and commentator in the 14th century. Jacob's father, Moses Schiff, was a broker for the Rothschilds. Schiff was educated in the schools of Frankfurt, and was first employed in the banking and brokerage business as an apprentice in 1861. After the American Civil War had ended in April 1865, Schiff came to the United States, arriving in New York City on August 6. He became a broker on November 21, 1866, and joined the firm of Budge, Schiff & Company in 1867. He became a naturalized citizen of the United States in September 1870.
