June 27, 1903, marked the day Aida de Acosta piloted a powered aircraft solo in Paris, becoming the first woman to achieve this feat. While many contemporaries viewed aviation as a masculine endeavor, she navigated a dirigible between Neuilly St. James and the Château de Bagatelle, operating the machine without formal pilot training.
The Santos-Dumont Dirigible
Brazilian aviator Alberto Santos-Dumont granted de Acosta access to his personal dirigible, identified as No. 9. During the excursion, which lasted ninety minutes, Santos-Dumont followed her on a bicycle to provide verbal guidance. Her flight predated the Wright brothers' heavier-than-air flight by nearly six months. She remains the only individual ever authorized by Santos-Dumont to pilot his private aircraft.

The flight occurred while de Acosta was traveling with her mother in France. Upon learning of the event, her parents expressed significant disapproval, fearing the scandal would hinder her prospects for marriage. Consequently, the family suppressed details of the flight for decades. The story only resurfaced in the 1930s during a dinner conversation involving her husband and Lieutenant George Calnan.
Public Health Advocacy
In 1922, de Acosta developed glaucoma. Under the treatment of surgeon William H. Wilmer, she lost vision in one eye but preserved sight in the other. This experience motivated her to lead a fundraising campaign that generated $3 million. These funds supported the 1925 founding of the Wilmer Eye Institute at Johns Hopkins Hospital. Later, in 1945, she served as the executive director of the Eye-Bank for Sight Restoration in New York.
Personal Life
Born in 1884 in Elberon, New Jersey, de Acosta was the daughter of Ricardo de Acosta and Micaela Hernández de Alba y de Alba. She married Oren Root III in 1908, with whom she had two children, Oren Root IV and Alva de Acosta Root. Following their 1922 divorce, she married Colonel Henry S. Breckinridge in 1927, remaining with him until their divorce in 1947.
