Thomas Power Lowry (born 1932) is an American author and retired physician.
A psychiatrist by training, he turned in the 1990s to writing historical non-fiction about the American Civil War. His reputation was damaged in 2011 when he made – and subsequently recanted – a written confession that he had  tampered with a document signed by President Abraham Lincoln held in the U.S. National Archives.

Early life and medical career

Lowry was born in Northern California, the son of a naval officer. He received an M.D. from Stanford University in 1957, later practicing as a psychiatrist and marriage counsellor. In the 1970s he and then-wife Thea Snyder Lowry (1932–2002) served on the staff of the Masters and Johnson Clinic  in St. Louis as part of the research team investigating sexual dynamics and relationships. During this period Lowry published what he would later describe as "several very dull medical books." Nonetheless, his 1976 work on the human clitoris was positively reviewed in the Journal of Sex Research. He was later a clinical associate professor at the University of California, San Francisco.

Later writing career
After retiring from a four-decade career in medicine, Lowry — assisted by a new wife, Beverly — shifted in the 1990s to writing non-fiction historical works. He has authored or co-authored more than 20 books in this field, the majority dealing with the American Civil War period. Much of the Lowrys' research was carried out at the U.S. National Archives in Washington, D.C., where, over the course of a decade, the Lowrys compiled a large index of thousands of previously uncatalogued Civil War documents. Lowry's first and best-known book on this subject, The Story the Soldiers Wouldn't Tell (1994), received a favorable review in The New York Times as "the first study of sexual behavior associated with the Civil War," and was praised in Esquire  as "amusing and fascinating." Two subsequent works on Civil War courts-martial, Tarnished Eagles (1998) and Tarnished Scalpels (2000; co-authored with Jack D. Welsh), were well-reviewed in Civil War Times and Kirkus Reviews, respectively. Lowry has occasionally published on other historic events, such as the Battle of Taranto and the sinking of the Titanic. His 2004 book on the Lewis and Clark Expedition earned him an award from the Lewis and Clark Trail Heritage Foundation.

Lincoln document forgery controversy
In January 2011, agents of the National Archives and Records Administration (NARA) obtained a signed confession from Lowry that  in 1998 he had smuggled a fountain pen into a NARA research room in Washington D.C., and used it to alter the date on a presidential pardon issued by Abraham Lincoln to a Union soldier who had been sentenced to death by court martial. A NARA press release announced that Lowry admitted to changing the handwritten year of the 1864 pardon so that Lincoln's signature appeared to be dated "April 14, 1865" – the same day Lincoln was assassinated at Ford's Theater. Lowry had cited the altered document in his 1999 book Don't Shoot That Boy! Abraham Lincoln and Military Justice. It was alleged that Lowry's motive was to gain publicity  by claiming that he, as an independent researcher,  had found what would have been the final official document signed by President Lincoln before his death.

Lowry subsequently recanted his confession, in which he detailed how he used a fountain pen containing fade-proof, pigment-based ink to alter the date of the pardon. Lowry now states that he signed the confession under duress after accepting a request to be interviewed by two NARA investigators at his home in Woodville, Virginia, and that any document-tampering was carried out by an unknown party prior to Lowry citing the pardon.

As the pertinent five-year statute of limitations on tampering with government property had expired, Lowry could not be criminally prosecuted. Nevertheless, his public reputation was severely damaged, and he received a lifetime ban from NARA's facilities. In 2021, forensic analysis of the pardon established that the ink of the number "5" in the date is different from the ink used in the rest of the document, indicating that the date was indeed forged.

Lowry has continued to produce history books, and maintains his innocence through his personal website.
