I think this question could have two answers. Mrs. Garfield established a library in her husband's memory after his death, but I think Truman's was the first established under the 1955 act that sanctioned Presidential Libraries. I believe that Truman liked the idea that FDR had generated by creating his library with the holdings at Hyde Park and this led to the official act of establishment.
