Hillary and I had a chance to visit the Harry S. Truman Museum & Presidential Library in Independence, Missouri. It's the second Presidential Library we've visited; we went to the Reagan Museum in Simi Valley, California back in 2013. Like the one for Reagan, the Truman museum includes a replica of the Oval Office from his era, plus a display of the office he used in retirement...
There was detailed information on several of his major policy decisions. One of them was his decision to give formal recognition to the (then) new nation-state of Israel. Truman was given a Torah scroll as a gift from the Jewish community, which is part of the display.
Another one of his guiding traits was decisiveness. His famous desktop motto, "The buck stops here," was given in contrast to "passing the buck" on to others.
Occasionally we were able to see marks of his faith and how it gave him perspective for his job as President. One was with the Bible that was used when he was first inaugurated - right after the death of FDR. The other was more about his view of the need for the moral influence of faith in society...
Truman lived up into my lifetime, but I was too young to know anything of it. He died the day after Christmas of 1972. Though he had only a 30% approval rating when he left office in 1953, today he is remembered fondly both by Democrats and Republicans.
