Raymond A. Spruance
At the end of World War II, Congress had authorized four Naval four-star officers to be promoted to Fleet Admiral. A staunch partisan of Admiral William Halsey, Jr., Vinson blocked the nomination of Admiral Raymond A. Spruance several times, although the majority thought him more deserving, to ensure that Halsey got the fourth billet. Congress eventually responded by passing an unprecedented act that specified that Spruance would remain on a full admiral's pay once retired until his death.
