who plays severide's parents on chicago fire
Kelly Severide The son of CFD Captain Benny Severide (Treat Williams), Kelly was raised singlehandedly by his mother, Jennifer Sheridan (Kim Delaney), after Benny left the family when Kelly was in elementary school. Although Kelly has since reconnected with his father, they still share a love-hate relationship. He is often known to the "white shirts" (high-ranking officers) as Benny's son[2][1] but never used his father's name to advance his career, instead carving out his own reputation as a highly competent firefighter.
Great Chicago Fire The fire started at about 9:00 p.m. on October 8, in or around a small barn belonging to the O'Leary family that bordered the alley behind 137 DeKoven Street.[3] The shed next to the barn was the first building to be consumed by the fire, but city officials never determined the exact cause of the blaze.[4] There has, however, been much speculation over the years. The most popular tale blames Mrs. O'Leary's cow, who allegedly knocked over a lantern; others state that a group of men were gambling inside the barn and knocked over a lantern.[5] Still other speculation suggests that the blaze was related to other fires in the Midwest that day.[1]
