Spruance was considered for a fifth star, but if I remember correctly the powers that be decided it would disproportionately give the Navy more top brass.
In order to honor him, however, an Act of Congress bestowed him his 4-star annual salary for life. Not too bad when you consider this was on top of his government service salary later on as Ambassador to The Philippines.
You left off George Washington...yes...THE George Washington. He was posthumously promoted to General of the Armies in 1976. And if my matheses adds up, that is after WW2. There are no clarifying remarks other than it had to be during or after WW2. LOL
George Dewey had 4 stars. John Pershing was made General of the Armies of the US which while outranking a 5 star general now, was awarded in 1919 before the creation of the 5 star ranking and so he only wore 4 stars.

Also, should George Washington technically be on here? He was considered both a 5 and a six star general. (In 1976)
