Regis Henri Post was born in 1870, attended Harvard University, and was a wealthy and prominent member of his community in Bayport (Long Island), New York. He was elected to the New York State Assembly in 1899 and served until 1900. President Theodore Roosevelt appointed him Auditor of Puerto Rico in 1903, Secretary of Puerto Rico in 1904, and Governor of Puerto Rico from 1907-1909. His tenure ended when Taft succeeded Roosevelt as President.
In November 1914 Post sailed to France with about twenty other men, including ten fellow Harvard alumni, to help France in the Great War. In December 1914, Post began work at the Section for the Wounded of the American Hospital in Paris (Neuilly), the parent organization out of which the American Field Service was formed. He held the rank of Section Commander in the Corps, was a member of the Hospital’s Ambulance Section Transportation Committee (as the first American member outside of the pre-war American community in Paris), and was also Adjutant of the Motor Corps with many administrative duties. He later served with the American Red Cross in 1917.
Post married Carolyn Beatrice Post in 1895. They divorced in 1922, and he later married Marguerite Post. The couple lived in Nantucket.
Regis Henri Post passed away in 1944.
The Regis H. Post Correspondence collection consists of nineteen typed letters from Post to his mother from November 22, 1914 to March 29, 1915 while he worked for the American Hospital Ambulance Service in Paris, and one photograph that was enclosed with the letter dated March 24, 1915. The letters have some handwritten corrections and notes written on them in an unknown hand. They were copied and typed by an unknown person at an unknown date, and may have originally been typed by Post. The letters are detailed accounts of Post’s activities, thoughts, observations, and emotions. They provide an early account of the work of the Ambulance Department of the American Hospital before the creation of the American Field Service, and allude to the politics of membership of the organization. The letters also provide interesting sketches of the Transportation Committee of the Hospital, and in them Post mentions individuals significant to the early history of the American Ambulance, including Lovering Hill, Richard Lawrence, and dentists Dr. George Hayes and Dr. William H. Potter. The photograph depicts a convoy of Ford chassis, which had been unloaded from the docks at Le Havre, on the road to the American Hospital in Paris.
The earliest Post letters predate the arrival of A.P. Andrew, the founder of the American Field Service, in France, and later letters do not mention Andrew, even though the two men must have worked together.
