Chicago Fire Cast Then and Now: See the evolution of Firehouse 51’s original stars from Season 1

Chicago Fire Cast images then and now Over the past decade, we’ve had to say goodbye to a

lot of Chicago Fire favorites. But some of the original characters have been around for years –

and we love looking back at photos of the cast and comparing them to now. Check out

our gallery below of photos of the Chicago Fire cast then and now. Chicago Fire is an NBC drama series about the personal and professional lives of firefighters, paramedics, and other rescue personnel at the fictional Firehouse 51 of the Chicago Fire Department. This series – which premiered in 2012 and was created by Dick Wolf, the like-minded man behind the Law & Order and FBI franchises – is the first show in NBC’s One Chicago series, which also includes including Chicago P.D. and Chicago Med.

Keep scrolling to see photos of the Chicago Fire cast then and now, including Kelly Severide, Matthew Casey, Christopher Herrmann, Otis, and more.
Kelly Severide (Taylor Kinney)


Even though Taylor Kinney is taking a break from Chicago Fire, his character Kelly Severide is a fan favorite for a reason. From being known as “the lady” in previous seasons to becoming a dedicated leader of Firehouse 51, we’ve seen his character grow tremendously over the past decade. We really hope that we’ll see Kinney again when Chicago Fire returns for Season 12.
Matthew Casey (Jesse Spencer)
While we thought we had seen the last of Jesse Spencer as Matthew Casey when the actor left in October 2021 – we were thankfully wrong! Casey reprized her role multiple times in Chicago Fire Season 11 and hasn’t ruled out a full-time return in the future. But we loved watching Casey in the show’s previous seasons (especially his relationship building and marriage to Gabby Dawson).
Wallace Boden (Eamonn Walker)
Chief Wallace Boden has been a core member of the cast of Chicago Fire since the beginning. He is a strong and inspirational leader who has helped Firehouse 51 overcome every major obstacle – good and bad. For a decade long, we also knew that Boden was a family man and would do anything for any member of his team. For example, when Stella (Miranda Rae Mayo) asked him to walk her down the aisle in Season 10 to her wedding to Kelly Severide.
David Eigenberg (Christopher Herrmann)
David Eigenberg’s Chicago Fire character Christopher Herrmann will always put a bright smile on our faces. A veteran firefighter, he has been a mainstay in the cast since Season 1 and has proven that he has a lot of knowledge to share (whether good or bad). But from Season 1 to now, we’ve enjoyed watching Herrmann’s relationship with his wife, Cindy, and their five children, Anabelle, Lee Henry, Luke, Max and Kenny James.
