Chicago Fire, now in its 10th season, has become a staple of NBC’s “One Chicago” universe, captivating fans with its gripping portrayal of the lives of Chicago’s brave first responders. Alongside its sister shows, Chicago P.D. and Chicago Med, the series delves into the personal and professional challenges faced by the crew of Firehouse 51. Produced by the legendary Dick Wolf, the show has earned acclaim for its authenticity, emotional depth, and the undeniable chemistry of its cast.
From realistic firefighting scenes created with controlled burns instead of CGI to employing a former firefighter as a technical advisor, Chicago Fire prides itself on delivering a genuine portrayal of the profession. Charlie Barnett, who played firefighter Peter Mills, shared in a 2013 interview with The Independent how much effort goes into making the set as authentic as possible: “All the tools are real… [Executive Producer] Dick Wolf made sure we had everything possible to make it real – the tools, the trucks, the gear, all of the people in the background are real firefighters.”
One of the show’s stars, however, brings a unique authenticity to his role thanks to his real-life experience in service — as a former Marine.
David Eigenberg: From the Marines to Firehouse 51
David Eigenberg, who plays the beloved Lieutenant Christopher Herrmann, brings more than just acting chops to Chicago Fire. Herrmann, known for his no-nonsense mentorship and fatherly demeanor, has become a pillar of Firehouse 51. Whether guiding rookie firefighters or cracking jokes with his colleagues, Herrmann embodies the wisdom and camaraderie of a seasoned firefighter.
But before joining the Chicago Fire cast in 2012, Eigenberg served in the United States Marine Corps. His time in the Marines shaped his understanding of service, discipline, and teamwork, qualities he channels into his portrayal of Herrmann. “It’s my job as an old firefighter to teach the young firefighters how to become old ones,” Herrmann famously says on the show, a sentiment that resonates deeply with Eigenberg’s military background.
Staying Connected to His Roots
Even after leaving the Marines, Eigenberg has maintained strong ties to his military past. He has collaborated with the United Service Organizations (USO), a nonprofit dedicated to supporting active-duty service members and veterans, providing resources, entertainment, and social connections.
Eigenberg’s connection to the USO extends beyond his public appearances. Following the events of 9/11, he met his wife, who is also a former service member, through the organization. In 2019, during a USO tour of the Naval Station Great Lakes in Illinois, Eigenberg took time to personally thank the station’s firefighters for their service. “They [firefighters] understand that you understand service,” he noted, reflecting the shared values between his past life as a Marine and his current role as an actor portraying a firefighter.
Honoring the Firefighting Profession
Eigenberg’s respect for the firefighting community is evident in his dedication to portraying Herrmann accurately. Along with his fellow cast members, he regularly consults with real firefighters to ensure their on-screen performances are true to life. His dual perspective as a Marine veteran and actor gives him a unique ability to honor both professions, bridging the gap between service and storytelling.
For fans of Chicago Fire, David Eigenberg’s journey from the Marine Corps to Firehouse 51 adds an extra layer of admiration for his character and the show. His commitment to authenticity and respect for those in service underscores why Herrmann remains one of the most cherished figures in the One Chicago universe.
