Time Quickens: The History of Sudden Succession and Succession Solutions Prior to the Twenty-Fifth Amendment provides a brief discussion of the framers’ view of succession and inability issues, as well as the historiography of both statutory laws and constitutional amendments dealing with those issues. The chapter also outlines the history of sudden presidential transitions and inabilities, and the solutions offered in their wake. When focusing on the Franklin D. Roosevelt/Harry S. Truman transition, which sets the stage of nuclear anxiety at the beginning of the era, what becomes clear is that with the destructive power of the bomb came a concomitant increase in presidential power and interest in the line of succession. Thus, Truman and Eisenhower worked more diligently toward succession and inability solutions than had their predecessors. The 1947 Presidential Succession Act and the Dwight D. Eisenhower/Richard M. Nixon letter agreement—key precursors to the Twenty-Fifth Amendment—were the results of their efforts.
