Of Scotch-Irish descent, Morrow was born in
Huntington, West Virginia. He moved with his parents, James Elmore and Clara (Johnson) Morrow to
Allegheny, Pennsylvania in 1875. His father James was principal of Marshall College, which is now
Marshall University. Morrow's great-great-grandfather Alexander Morrow had immigrated to America from Ireland around the year 1803. Before this, Alexander's ancestors had come from Scotland. After graduating from
Amherst College in 1895, Morrow studied law at
Columbia Law School and began practicing at the law firm
Simpson Thacher & Bartlett in New York City. In 1903, he married
Elizabeth Reeve Cutter, his college sweetheart, with whom he had four children.
Anne Morrow, his daughter, later married
Charles A. Lindbergh, whom she met while her father was Ambassador to Mexico. In 1913, he became a partner at
J.P. Morgan & Co., one of the largest and most powerful commercial and investment banks in the United States during this era, financially backing industrial giants such as
General Motors and
3M. As a partner at Morgan, he served as a director on many corporate and financial boards. With the onset of
World War I in Europe, the bank lent
Britain and
France large sums of money with which they purchased war materials in the U.S. When the United States entered the war, Morrow became the director of the National War Savings Committee for the State of
New Jersey. He also served abroad as adviser to the
Allied Maritime Transport Council and as a civilian member of the Military Board of Allied Supply. With his proven logistical and intellectual talents, Morrow was sent to France by President Woodrow Wilson to serve as chief civilian aide to
General John J. Pershing. '' cover, October 12, 1925 In 1925, Morrow was summoned by his old Amherst College classmate and friend,
President Calvin Coolidge, to lead a board of inquiry into aviation in the U.S. In September of that year, Coolidge ordered the
court-martial of Colonel
Billy Mitchell of the
Army Air Service for "
conduct prejudicial to good order and military discipline." The trial was scheduled for November. Anticipating adverse political reaction to the trial, and seeking to shape aviation policy in accordance with his own economic views, Coolidge asked Morrow to head a board of military and civilian aviation experts to inquire into all aspects of aviation. The board's report, published before Mitchell's conviction, recommended the creation of an Air Corps within the Army equivalent to the
Signal Corps or
Quartermaster Corps, which resulted in the establishment of the
U.S. Army Air Corps in July 1926. ==Ambassador to Mexico==
