Rachel A. Shelden says that for two decades Guelzo,
- "has been at the forefront of Civil War–era scholarship. In particular, he has focused his analytical efforts on the life and legacy of Abraham Lincoln, publishing books covering the Lincoln-Douglas debates, the origins of the Emancipation Proclamation, and Lincoln’s presidential leadership, among others."
Guelzo was born in Yokohama, Japan. His earliest degrees were a BS in Biblical Studies from Philadelphia Biblical University and a MDiv from Reformed Episcopal Seminary.  He earned an MA and PhD in history from the University of Pennsylvania. He joined the History department of Eastern University (St. Davids, Pennsylvania) in 1991. He was the Grace F. Kea Professor of American History at Eastern, where he was also Moderator of the Faculty Senate (1996-98). From 1998 to 2004, he served as Dean of the Templeton Honors College at Eastern. He joined the History department at Gettysburg College in 2004.
One of Guelzo's early works, 'For the Union of Evangelical Christendom: The Irony of the Reformed Episcopalians, 1873-1930, won the Albert C. Outler Prize in Ecumenical Church History from the American Society of Church History in 1993.  He began work in 1996 on an 'intellectual biography' of Lincoln, Abraham Lincoln: Redeemer President (1999), which won the Lincoln Prize for 2000 and the 2000 Book Prize of the Abraham Lincoln Institute. He followed this with Lincoln's Emancipation Proclamation: The End of Slavery in America (2004), which became the first two-time winner of the Lincoln Prize (for 2005) and the Book Prize of the Lincoln Institute.
In addition to these books, he has produced editions of Manning Ferguson Force's From Fort Henry to Corinth (1989) and Josiah Gilbert Holland's Life of Abraham Lincoln (1998), as well as co-editing a volume of essays on Jonathan Edwards, Edwards In Our Time: Jonathan Edwards and the Shaping of American Religion (with Sang Hyun Lee, 1999) and The New England Theology: From Jonathan Edwards to Edwards Amasa Park, an anthology of primary sources on the New England theology from 1750 to 1850, with Douglas R. Sweeney (2006). His latest books include Lincoln and Douglas : The Debates That Defined America (2008), which led to an appearance on Comedy Central's "The Daily Show with Jon Stewart" on February 27, 2008; Abraham Lincoln as a Man of Ideas (2009), collection of his previously-published essays; and "Lincoln" (2009), a volume in Oxford University Press's "Very Short Introduction" series.
Pinsker notes that Guelzo, with his religious training, often emphasizes religious themes that other historians have neglected. Guelzo argues that Lincoln championed the cause of individual rights partly because of his profound fatalism and what Guelzo identifies as, "a lifelong dalliance with Old School Calvinism."
Shelden has noted that Guelzo's Fateful Lightning: A New History of the Civil War and Reconstruction (2012) is heavily focused on Lincoln. She complains that little in the book is new, and much is based on old fashioned historiography. She says he underplays the recent scholarship on the home front, environmental concerns, and medical issues, while giving only cursory attention to the black experience or to the complexities of Reconstruction.
Guelzo has been an American Council of Learned Societies Fellow (1991–1992), a Visiting Research Fellow at the McNeil Center for Early American Studies at the University of Pennsylvania (1992–1993), a Fellow of the Charles Warren Center for the Study of American History at Harvard University (1994–1995), and a Visiting Fellow, Department of Politics, Princeton University (2002–2003 and 2010–2011). He was appointed by President George W. Bush to the National Council on the Humanities in 2006.
