When William Henry Harrison died in office, some thought John Tyler would then be "Acting President" (for 47 months of the 48-month term), but he insisted on being called President. He got away with it, and he, Andrew Johnson, Chester Alan Arthur, Theodore Roosevelt, Calvin Coolidge, and Harry Truman were all considered Presidents when the President died in office. The 25th amendment finally stated in so many words that "in case of the removal of the President from office or of his death or resignation, the Vice President shall become President," but the 20th and 22nd amendments had already effectively conceded the point.
