The sirens at Firehouse 51 are sounding a somber note this year. As Chicago Fire marches through its 14th season in 2026, the show has officially bid farewell to one of its “Originals”—an exit that is being hailed by fans and critics alike as the most emotional departure in the series’ history.
After 13 years of bravery, brotherhood, and countless heart-pounding rescues, the departure of David Eigenberg as Christopher Herrmann has left a void that no one in the One Chicago universe was ready for.
The Heart of 51: Why Herrmann’s Exit Hits Different
While other major characters have moved on over the years—most notably Chief Boden and Sylvie Brett—Herrmann represented the “old guard.” He was the salt-of-the-earth veteran who kept the firehouse grounded. His exit isn’t just a loss of a lieutenant; it’s the loss of the show’s moral compass and its most reliable source of wisdom.
The storyline leading up to his departure was meticulously crafted. After seasons of battling health scares and the physical toll of a decade-plus on the job, Herrmann finally made the gut-wrenching decision to prioritize his family and his long-term health. The final episode featured a series of “passing the torch” moments that didn’t leave a single dry eye in the audience.
The Most Emotional Goodbye
What made this exit “the most emotional ever” was the tribute paid by his fellow firefighters. In a stunningly shot final sequence, the entire house—past and present—gathered to give Herrmann a traditional “walk-out.”

The “Mouch” Moment: The most poignant part of the episode was the final conversation between Herrmann and his best friend, Mouch (Christian Stolte). Their bond has been the backbone of the show’s humor and heart, and seeing them say goodbye was a true end-of-an-era moment.

The Legacy of Molly’s: Fans are also left wondering about the future of Molly’s, the iconic bar that has served as the social hub for all three Chicago shows. Herrmann’s departure raises questions about who will step up to keep the legacy of the bar alive.
A Masterclass in Writing
Showrunners handled Eigenberg’s exit with a level of respect rarely seen in long-running procedurals. Rather than a tragic “shock value” death, Herrmann was given a hero’s retirement. It was a celebration of a character who proved that you don’t need to be the “lead” to be the most important person in the room.
“David Eigenberg didn’t just play a character; he built a family,” said one of the series’ producers in a recent interview. “Ending his 13-year journey was the hardest thing we’ve ever had to write, but it was also the most beautiful.”
What This Means for Firehouse 51
With Herrmann gone, the dynamic of the house is set for another massive shift. Lieutenant Kidd and Severide are now the true veterans, and the pressure is on the younger recruits to uphold the standards Herrmann set. His departure marks the definitive transition from the “Old 51” to a new generation of firefighters.
