Ruth Morgan (October 12, 1870 – March 11, 1934) was an American peace activist during the late nineteenth and early twentieth centuries.

[4][5] Evaluating the nursing care and social needs of the soldiers serving with the American Expeditionary Forces upon her arrival, she quickly determined that significant improvements were needed and established "Flying Squadrons" of nurses "to be sent 'flying' over France in motor cars to each mobile, evacuation or military hospital where any American soldiers, brigaded with the French, had been sent."

[9][10] Their younger brother, journalist Gerald Morgan Sr. (1879-1948), reported on the Nazi invasion of Belgium for the New York Tribune during World War II.

[23][24][25][26] She is credited with the planning and implementation of "Flying Squadrons" of nurses who transported food and medicine by automobile to "mobile, evacuation or military hospital[s] where any American soldiers, brigaded with the French, had been sent."

Men who had gone over the top, who had become unconscious on the battle ground and were carried into a French hospital, woke out of their sick faint fearing they had been taken prisoner by the Germans.

[29] On April 19, 1922, Morgan presented the opening remarks at a highly publicized New York City League of Women Voters' event, during which she introduced Viscountess Nancy Witcher Langhorne Astor, the American-born, British politician who had become the first woman to be seated as a Member of Parliament in the United Kingdom.

Lady Astor, who had returned to America to participate as a delegate to the Pan-American Conference of Women in Baltimore, Maryland from April 20 to 29, gave a pre-conference address to the New York audience, which included Carrie Chapman Catt and other leading women's rights activists, as well as Morgan's fellow Colony Club members, civic leaders and prominent members of society.

Following funeral services at Grace Episcopal Church in Manhattan on March 13, which were attended by her family and friends, including U.S. Secretary of Labor Frances Perkins and Sara Roosevelt, the mother of U.S. President Franklin D. Roosevelt, Morgan was interred in the Morgan family's mausoleum at the Saint James Episcopal Churchyard in Hyde Park, New York.
