The story of Sigma Nu began during the period following the Civil War, when a Confederate veteran from Arkansas enrolled at the Virginia Military Institute in Lexington Virginia. That cadet was James Frank Hopkins, and it is to him and two of his classmates that Sigma Nu owes its existence. When Hopkins enrolled at VMI, the south was in a state of turmoil and just beginning to recover from the devastating military defeat it had suffered. The Virginia Military Institute was highly recognized for its civil engineering program and the South badly needed to repair its bridges and railroads. At the Institute cadets suffered, not only of the ravages of war and a disrupted homelife, but because of the system of physical harassment imposed on lower classmen by their fellow students in the upper classes.
Hopkins had experienced military subservience during the war, and was willing to tolerate a reasonable amount of constraint intended to induce discipline. However, Hopkins was unwilling to accept any amount of hazing then being allowed at VMI. Not one ounce of hazing was he willing to suffer and he was doggedly adamant about eliminating it.
