Truman is a 1992 biography of the 33rd President of the United States Harry S. Truman written by popular historian David McCullough. The book won the 1993 Pulitzer Prize for Biography or Autobiography. The book was later made into a movie with the same name by HBO.
The book provides a biography of Harry Truman in chronological fashion from his birth to his rise to U.S. senator, vice-president, president, following his activities until death, exploring many of the major decisions he made as president, including his decision to drop the atom bomb on Hiroshima and Nagasaki, his meetings and confrontation with Joseph Stalin during the end of World War II, his decision to create the Marshall Plan, his decision to send troops to the Korean War, his decision to recognize the state of Israel, and his decision to desegregate the United States armed forces.
After writing Mornings on Horseback, which was McCullough's first biography and consisted of an in-depth look at a small period in the life of former United States President Theodore Roosevelt, McCullough wanted to do a more full biography, "a mural instead of a Vermeer." At first, McCullough attempted to write a biography about Pablo Picasso, but abandoned the project in favor of doing a book on Truman.
McCullough decided that he would structure the story of Truman's biography in chronological fashion. McCullough explained his reasoning for this decision by stating: "It's been very fashionable lately to begin biographies anywhere but at the beginning, heaven forbid. But I didn't want to do anything tricky or fashionable because [Truman] was neither of those things. Harry Truman was a 19th-century man and I decided I would proceed as a great 19th-century biographer would, or as Dickens would."
In effort to better understand his subject, McCollough took several actions to emulate the life and activities of Truman. For instance, he would begin each day with a brisk early-morning walk, just as Harry S. Truman did. He also lived in Truman's hometown Independence, Missouri for a little while. He also raced through the United States Capitol retracing the path Truman ran when he was summoned to the White House after the death of Franklin D. Roosevelt.
To help research the book, McCullough interviewed hundreds of people that knew Truman, including relatives and Secret Service Agents, read numerous letters and documents, and read almost all the books written about Truman.
While working on the book McCullough would read every draft page aloud to his wife and having her read the pages back to him. McCullough explained this practice by stating: "You can hear things that you cannot see. Redundancies, awkward expressions. Painters often look at their work in the mirror because you can see flaws that you don't see looking straight at a canvas."
McCullough wrote the book Truman over a period of 10 years. McCullough stated that during that 10 years many things changed in his life, "In those 10 years, my youngest daughter changed from a girl into a woman, both my parents died, grandchildren were born, we moved our residence twice, we put a child through college and law school, and paid off a mortgage." 
McCullough felt a compulsion to get the book finished before the 1992 presidential campaign in response to the shallow political debates that were occurring in Washington, D.C. McCullough said, "I felt that something needed to be said before people made a choice. This book is about the country, not just about Harry Truman. It's about who we are and what we can be."
While McCullough was able to gain insights into Truman based on his research, there were questions that remained unanswered to McCullough such as why Truman's wife left him alone in Washington so often. The usual explanation among historians was that Bess hated the heat and her mother was ill, but McCullough has expressed doubts about this explanation stating that "[Bess] was away so often and [Truman's] letters to her were so plaintive, his need for her to be there so real. I don't know."
McCullough has stated that he intended Truman to be not only for "the Arthur Schlesingers and the academics" but instead intended the book for "your grandmother," and other common folk including present and future politicians so "they may see, even when flawed, how great a man in [the office of the President] can be."
Most reviewers praised the book when it came out. One notable dissent was an article in the New Republic titled "Harry of Sunnybrook Farm" by Ronald Steele where he called the book a "1000 page valentine." 
Gene Lyons at Entertainment Weekly gave the book an A, stating that "No brief review can begin to do justice either to Truman or to the monumentally persuasive job McCullough has done re-creating his life and times.... Immeasurably aided by Truman's vividly written diaries and letters to his beloved wife, Bess, McCullough brings the man and his times to life with painstaking clarity."
The book won McCullough his first Pulitzer Prize, in the category of "Best Biography or Autobiography."
