John Bartlow Martin (Hamilton, Ohio, 4 August 1915 – Highland Park, Illinois, 3 January 1987) was an American diplomat, author of 15 books, ambassador, and speechwriter and confidant to many Democratic politicians including Adlai Stevenson, John F. Kennedy, Robert F. Kennedy, Lyndon B. Johnson, and Hubert Humphrey.
Martin was born in Hamilton, Ohio to John, a carpenter and contractor, and Laura Bartlow Martin, and as a young child moved to Indianapolis. Martin grew up in an unhappy childhood, plagued by the death of his two brothers. He graduated from high school at age 16 and was expelled in his first year from DePauw University, but he later graduated there with a degree in journalism.
With the impact of his dark childhood and onset of the Great Depression, Martin's early journalism career focused on deep concern for the underprivileged and forgotten, such as criminals, the impoverished, the working class, and the mentally ill. His work appeared in such publications as Saturday Evening Post, LIFE, Colliers, Atlantic Monthly, and Harper's. He won the highest magazine writing honor, the Benjamin Franklin Magazine Award, for four consecutive years.
Martin was hired in 1952 as a speechwriter by Illinois Governor Adlai Stevenson, and later worked on the Kennedy presidential campaign. He served as U.S. Ambassador to the Dominican Republic from 1962 to 1964. Martin arrived shortly after the assassination of the dictaor, Rafael Trujillo. He became very close with the new president, Juan Bosch. Martin resigned shortly after the Kennedy assassination, but he returned to the Dominican Republic as a special envoy in 1965 during the invasion dispatched by Johnson.
