1. A Familiar Face in Firehouse 51
Since day one of Chicago Fire, David Eigenberg has played Christopher Herrmann—a character who embodies the grit, resilience, and heart of a seasoned firefighter. As a founding member of the Firehouse 51 crew, Herrmann has faced his share of dramatic turns: tragic losses, moral dilemmas, near-death experiences, and moments of humor and warmth that only a character like him can deliver.
In the show’s most recent seasons, Herrmann has taken on more leadership responsibilities. His attempt to take the Chief test showcases both ambition and the vulnerability that comes with stepping outside one’s comfort zone. David Eigenberg portrays these nuances with the kind of layered performance that only an actor of his caliber can provide.
Fans love Herrmann because he’s not perfect—he’s human. And a big reason that humanity feels so real is because David Eigenberg taps into his own experiences to bring authenticity to the role.

Their enduring relationship, which spans more than two decades, is built on mutual respect and shared values. The couple has two children, and Eigenberg often speaks about how his family keeps him balanced and inspired.
While many celebrities are known for flashy lifestyles, David Eigenberg stands out for his quiet consistency. He splits his time between shooting in Chicago and spending quality moments with his family, often staying away from the Hollywood limelight unless it’s for a cause he believes in.
In an interview, Eigenberg shared that fatherhood transformed him and gave him a deeper understanding of his role as Herrmann, especially as the character grapples with family dynamics on the show.
4. Advocacy and Social Impact

Using his fanbase and online influence, David Eigenberg successfully brought attention to the cause while offering fans a personalized connection through video messages. It’s this thoughtful use of his public presence that sets him apart from many in the entertainment industry.

While most fans know David Eigenberg from Chicago Fire, his acting résumé spans decades. He’s perhaps best remembered for playing Steve Brady, Miranda’s lovable on-again, off-again partner on HBO’s Sex and the City. That role showed off his ability to bring warmth and subtlety to romantic storylines—a skill he’s continued to hone throughout his career.
