When Lt. Col. Harold Larsen walks across the NIU campus, he carries more than just the weight
of textbooks and lesson plans — he carries nearly two decades of service, leadership and unwavering commitment to shaping future leaders. 
Originally from Columbus, Nebraska, Larsen is a man of discipline and purpose, values instilled in him through 19 years of active duty in the U.S. Army. Now, as professor and chair of our Department of Military Science, he’s continuing to fulfill the dream he had as a child: Serving in the Army — only now, his mission is to develop the next generation of Army leaders.
“I wanted to join the Army,” Larsen said, “and I’m still doing it.”
In 2024, Larsen brought his extensive experience and passion for service to NIU. Since then, he has immersed himself in the campus community with the same energy and dedication he brought to his military career.
“I love the community that exists here,” he shared. “I was welcomed by all members of the university, and I felt at home immediately.”
His work now focuses on mentoring and training ROTC cadets — future Army officers who will
soon be called upon to lead others in challenging environments. For Larsen, it’s more than just instruction. It’s about building character, instilling values and guiding young adults toward a meaningful future.
“I enjoy sharing my experiences with them and knowing I’m making a difference in their future,” he said. “It’s great to connect with the next generation and watch them grow and develop.”
Those connections are what Larsen finds most fulfilling — both personally and professionally. Whether he’s leading cadets through physical training or sharing insights from his own path, his goal is always the same: Develop leaders of character for the U.S. Army.
That mission dovetails perfectly with NIU’s own core values of ethics, integrity, service and stewardship — values that echo the Army’s emphasis on loyalty, duty, respect, selfless service, honor, integrity and personal courage.
Larsen, a first-generation college graduate, earned his B.A. degree in history from Creighton University and later earned his master’s degree in business and security management from Webster University.
He knows the challenges that come with forging a new path, and he has advice for students walking similar roads.
“Work hard and live the golden rule,” he said. “Help each other out and don’t be afraid to ask questions.”
Perhaps most emblematic of his dual identity as soldier and professor was the recent commissioning of six new second lieutenants, a milestone he recalls with pride.
