Rutherford B. Hayes was elected President of the United States in the very controversial 1876 election in which he squeezed into the White House after a razor-thin margin in the electoral college. He was fairly successful in office, but declined to run for a second term and retired from active politics. Hayes is well-remembered in his hometown of Delaware, Ohio (I've been there), but has largely receded from the American historical memory.
But not in Paraguay.
This small country in South America was once much larger until Argentina, Brazil, and Uruguay ganged up on it to deprive it of almost half of its territory. Perhaps as much as two-thirds of the Paraguayan population died in the war.
In the postwar settlement, Argentina and Paraguay asked the United States to arbitrate their border dispute. President Hayes ruled in favor of Paraguay, for which the surviving Paraguayans were very grateful.
Even today, Paraguay remembers President Hayes. Atlas Obscura tells us that there's a museum, the Villa Hayes, in Presidente Hayes, which is one of the 17 departments (districts) that comprise the modern nation of Paraguay.
