But behind this beloved character is a man whose real-life story is just as inspiring as the one he plays on screen.

Herrmann Is the Heart of Firehouse 51
While Firehouse 51 is packed with strong personalitiesāfrom Severideās cool confidence to Kiddās fierce ambitionāHerrmann remains the glue. Heās the one who always steps up when things fall apart. Heās not afraid to get loud, stand his ground, or crack a joke to break the tension.
In Season 13 alone, Herrmann delivered some of the show’s most heartfelt scenesācomforting traumatized team members, standing up for whatās right, and keeping Mollyās running as a second home for the squad.
