Conan O’Brien has been hit by double heartbreak after losing both of his parents just three days apart. The beloved talk show host’s father, Dr. Thomas O’Brien, died on Monday, December 9, at his home in Brookline, Massachusetts, per The Boston Globe. He was 95. Then, just three days later, Conan’s mother, Ruth Reardon O’Brien, passed away on Thursday, December 12, also at their home. She was 92. Conan and his brother, Justin, spoke to the Globe about their parents, with the former crediting his father with instilling in him a love of comedy. “The loudest I’ve ever heard anybody laugh was sitting next to him in a theater watching Peter Sellers in a Pink Panther movie,” Conan recalled. “He was often the funniest guy in the room. And when he would laugh, his whole body would convulse and he would almost hug himself.” Ruth and Dr. Thomas O’Brien; Legacy.
