Conan O’Brien’s Parents Die 3 Days Apart

The parents of Conan O’Brien, the longtime late-night television host and a star in the comedy world, died this week within days of one another.

Thomas Francis O’Brien, 95, an epidemiologist, and Ruth Reardon O’Brien, 92, a lawyer who made strides for women in the legal field, both died at their home in Brookline, Mass., according to the Bell O’Dea Funeral Home. Dr. O’Brien died on Monday, and Ms. O’Brien, died on Thursday.

Happy families are not exactly a common topic in comedy. The parents of Conan O’Brien, 61, were not only celebrated in their respective fields but by the most well-known of their six children.

Conan O’Brien credited his father with introducing him to comedy and described him in an interview this week in The Boston Globe as “the funniest guy in the room.” He added that his father had a “voracious appetite for ideas and people and the crazy variety and irony of life.”

Thomas O’Brien spent most of his career at what is now Brigham and Women’s Hospital in Boston, where he was the first director of the infectious diseases division, and was on faculty at Harvard Medical School. He also was a co-founder of the Collaborating Centre for Surveillance of Antimicrobial Resistance for the World Health Organization. He became known for his work around antibiotic-resistant bacteria.
