He tends to be particularly remembered for his fluffs: his term of office began by pardoning his predecessor (and even then he fluffed the announcement, getting the month wrong) and ended when in debate with Jimmy Carter he stated that there was "no Soviet domination of Eastern Europe", a pretty massive fluff.
In fact Ford was perfectly well aware of the situation in Eastern Europe, and presumably simply had one of those foot-in-mouth moments that happen to us all from time to time (though hopefully not in the defining public appearance of our careers). By negotiating the Helsinki Accords, he laid the foundations for the strengthening of civil society and embedded human rights in the geopolitical discourse of Europe, laying the foundations for the collapse of Communism two decades later to take a largely peaceful course (with some rather obvious exceptions). Those of us who live in a united, peaceful and free Europe today owe him, and I'll raise a glass to his memory this evening.
It should also be noted that he took a markedly more liberal line on LGBT rights than most of his own party. But the 1970s were a different time.
