(2005). He also wrote a memoir, A Life with History (2004), detailing his years on the nation's top history faculty, where he witnessed the privileged mostly white WASP student body grow in diversity, describing it as "not a refuge from reality but an alternative reality". Perhaps Blum's most widely read work was The National Experience: A History of the United States (1963), a university history textbook he edited and co-authored with William S. McFeely, Edmund S. Morgan, Arthur M. Schlesinger Jr. and Kenneth M. Stampp. His 1954 book The Republican Roosevelt restored the reputation of U.S. President Theodore Roosevelt, rescuing it from Henry F. Pringle's Pulitzer Prize-winning 1931 biography Theodore Roosevelt: A Biography, which portrayed him as a blustering politician who never grew up that kept him from being taken seriously. However Blum's prose came under attack: "In contrast to many biographers, Blum is not a natural writer; his style is neither elegant nor smooth. Instead, his sentences are often awkward and clunky and force the reader to sip rather than drink freely." A specialist on the New Deal, Blum wrote From the Morgenthau Diaries (3 vols., 1959–1967), a biography closely based on the diaries of Henry Morgenthau, Jr. (1891–1967), United States Treasury Secretary in 1934–1945. Blum was also prolific as an editor, serving as co-editor of The Letters of Theodore Roosevelt (8 vols., 1951–1954), edited by Elting E. Morison. In 1980 Blum published Liberty, Justice, Order: Writings on Past Politics, 13 essays containing profiles of 10 political leaders representing the first seven decades of the 20th century, including Theodore Roosevelt, Herbert Croly, Mark Hanna, Woodrow Wilson, Franklin D. Roosevelt, Eleanor Roosevelt, Henry Wallace, Archibald MacLeish, Walter Lippman, and Earl Warren, bringing out their efforts to foster social justice and economic equality. He also edited the letters of Walter Lippmann and Henry A. Wallace. Film and television Blum made a cameo appearance as himself in the 1983 Woody Allen film Zelig, and he has appeared in various documentaries on PBS such as the American Experience series, including Theodore Roosevelt in 1996 with fellow historian David McCullough. In 1999 he appeared in "The Great War" segment of The Century: America's Time.
