[LincolnMan]

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.

Laurie:
You are correct. The answer is complicated. FDR is also another choice- and so is Hayes. I was thinking Garfield when I posted the question. No simple answer on this one.
