Dennis Hart Mahan was a graduate of West Point, who after graduating continued his education in Europe and upon his return became Professor of Civil and Military Engineering at the Academy.  In addition to this work on drawing, he was the author of six other text books, focusing on engineering, fortification, geometry, and mechanics.  They were published in South as well as the North and had influence on CSA engineers and tacticians as well as their counterparts in the Union cause.  His works were also translated in to German and used in Prussian military academies. Mahan was considered one of the most influential teachers and innovators of his time who had significant impact on the conduct of the War on both sides of the conflict.  After the War he was forced to resign from the Academy and committed suicide in 1871.
