This historical study by Louis Torres examines the conception, prolonged construction, and eventual completion of the Washington Monument in Washington, D.C., focusing particularly on the role of the United States Army Corps of Engineers. Anchored in archival research and military engineering history, the book outlines political debates, funding struggles, and technical challenges from the monument’s early planning stages in the 19th century through its dedication “to the immortal name and memory of George Washington.” It also highlights key figures such as Lieutenant Colonel Thomas Lincoln Casey and his engineering team who oversaw the monument’s completion and stewardship before the National Park Service era
