Regis Henri Post

Regis Henri Post (January 28, 1870 – October 5, 1944) was a New York politician and the governor of Puerto Rico from April 17, 1907, to November 6, 1909.

His mother remarried to his father's 2nd cousin once removed, Charles Alfred Post (1844-1921).

His governorship was extremely controversial, as his frequent disagreements with the Puerto Rico Legislature led to the Legislature's failure to pass any budget in 1909, resulting in a political crisis on the island and passage of the Olmsted Amendment at the request of President William Howard Taft.

Following Post's time in Puerto Rico, he worked with the American Ambulance Corps in France from 1913 to 1914.

Post married thirdly Marguerite Denis de Lagarde on April 5, 1933.

His great-great-grandfather was Jotham Post, Jr., a United States Representative from New York and an assemblyman.
