D.M. Giangreco is an American military historian and author known for his extensive research and writing on World War II, particularly the Pacific War and the decision to use atomic weapons against Japan.

His most notable works include "Hell to Pay: Operation DOWNFALL and the Invasion of Japan, 1945-1947" and "Dear Harry... Truman's Mailroom, 1945-1953: The Truman Administration Through Correspondence with 'Everyday Americans.'" These publications have contributed significantly to the scholarly discussion of the Pacific War's conclusion and President Truman's decision-making process. Giangreco's research has challenged several conventional narratives about the atomic bombings of Japan, particularly through his detailed analysis of casualty projections for Operation Downfall, the planned invasion of Japan. His work has been cited in numerous academic publications and has influenced historical understanding of this critical period. The historian has received multiple research and writing awards, including the Moncado Prize from the Society for Military History. His articles have appeared in various scholarly journals and publications, including Military Review, Journal of Military History, and Pacific Historical Review.

Readers appreciate Giangreco's thorough research and use of primary sources, particularly in "Hell to Pay" and "Dear Harry." Many point to his inclusion of previously unreported documents and casualty projections. Several reviews note his clear writing style makes complex military planning accessible. Amazon reviewer R. Martin said "explains high-level strategy without getting bogged down in jargon." Main criticisms focus on dense statistical data that some found overwhelming. A few Goodreads reviews mentioned repetitive sections in "Hell to Pay." One reader said "could have been condensed by 100 pages."
