Working With Roosevelt" by Sam Rosenman is a superb primary historical (Rosenman writes from his first-hand experience) account about President Franklin D. Roosevelt. As one of FDR's top speech writers, Rosenman's insight into the workings of FDR's administration and the associated personalities is a must for the serious history student and anyone interested in gathering advanced leadership DNA. A political science treasure trove for those running for elected office.
Samuel Irving Rosenman [1896-1973] was an American lawyer, judge, Democratic Party activist and presidential speechwriter. He coined the term "New Deal" and helped articulate liberal policies during the heyday of the New Deal coalition. He was the first person to hold the position of White House Counsel.
