When Chicago Fire said goodbye to Benny Severide, the complicated but fiercely loyal father of Kelly Severide, the episode was heart-wrenching. But real-life grief struck even deeper when Treat Williams, the beloved actor behind Benny, passed away suddenly on June 12, 2023, at the age of 71.
A Legacy Beyond the Firehouse
Treat Williams didnât appear in many episodes of Chicago Fire, but every scene he was in mattered. As Benny Severide, he brought depth, tension, and humanity to the show. Benny wasnât a perfect fatherâhe had a complicated relationship with Kelly and a tangled pastâbut Treat played him with such quiet gravitas that fans could never write him off. His presence reminded us that even heroes have unresolved family wounds.
Williamsâ portrayal turned what couldâve been a one-dimensional “tough dad” role into something raw and real. Whether he was offering fatherly advice or walking away at the wrong moment, Benny was authenticâand that was all Treat.
His Tragic Death
Treat Williams died in a motorcycle accident in Dorset, Vermont. He was reportedly struck by a car while turning into a parking lot. The suddenness of his death left Hollywood and his fans in deep mourning. At 71, Williams was still active, vibrant, and very much in love with his craft. He had been acting for over four decades, known for roles in Hair, Everwood, and Once Upon a Time in America, among many others.
His family described him as âfull of love, adventure, and kindness,â and the Chicago Fire cast poured out tributes in the days following the news.
What He Meant to Chicago Fire
Although Benny Severide died offscreen in Season 7, his impact lingered. His funeral marked a major emotional turning point for Kelly. It wasnât just about losing a fatherâit was about losing the hope for healing, reconciliation, and all the conversations they never had. That emotional weight was carried forward in the story, and Treat Williamsâ performance laid the groundwork for it.
When fans learned of Treatâs real-life passing, many went back to rewatch his Chicago Fire scenes. Suddenly, the moments hit even harder: his proud glances at Kelly, his flawed attempts at connection, and even his stubborn silence. All of it felt more poignant.
A Quiet Goodbye That Wonât Be Forgotten
Treat Williams may no longer be with us, but his workâand his spiritâremain embedded in every scene he touched. In Chicago Fire, Benny Severide will always be the complicated father figure whose absence speaks louder than his presence. And in real life, Treat Williams will always be remembered as a consummate actor, a gentle soul, and a man who left us too soon.
As Kelly Severide once said, âHe wasnât perfect, but he was mine.â
And to many fans of Chicago Fire, so was Treat Williams.
