Junius Spencer Morgan

United States financier

Junius Spencer Morgan I (April 14, 1813 – April 8, 1890) was an American banker and financier, as well as the father of John Pierpont "J.P." Morgan and patriarch to the Morgan banking house.

In 1864, he established J. S. Morgan & Co. in London as the successor to George Peabody & Co., of which he was junior partner.

With his son's aid, Morgan grew his banking house into a trans-Atlantic financial empire that included firms in London, New York City, Philadelphia, and Paris.

By the time of his death in 1890, the Morgan banks were dominant forces in government and railroad finance, and his was the pre-eminent American banking house.
