Conan O’Brien is grieving the loss of his parents, Dr. Thomas O’Brien and Ruth Reardon O’Brien, who passed away within three days of each other. Thomas was 95, and Ruth was 92.
Thomas died on Monday, following a period of declining health, according to The Boston Globe. Ruth passed away on Thursday at the couple’s home in Brookline, Massachusetts, as noted in an obituary shared by the Bell-O’Dea Funeral Home.
A Legacy of Achievement
Dr. Thomas O’Brien, born on January 28, 1929, in Worcester, Massachusetts, had an illustrious career in medicine. After graduating cum laude from Harvard Medical School in 1954 on a full scholarship, he dedicated over six decades to groundbreaking research in antimicrobial drug resistance. He served as the inaugural director of the infectious diseases division at what is now Brigham and Women’s Hospital and was an associate professor at Harvard Medical School.
Ruth Reardon O’Brien, born on December 16, 1931, in Worcester, Massachusetts, was a trailblazer in law. She graduated from Yale Law School in 1957, one of only four women in her class, and served as vice president of the student government. She began her career clerking for Chief Justice Raymond Wilkins of the Massachusetts Supreme Judicial Court. Later, as a real estate attorney at Boston’s Ropes & Gray law firm, Ruth made history in 1978 as the firm’s second female partner.
A Lifetime of Love and Family
Thomas and Ruth met through her brothers and were married in 1958. Together, they raised six children, including comedian and former late-night host Conan O’Brien.
Conan shared fond memories of his father with The Boston Globe, describing him as a man with a remarkable sense of humor. “He was often the funniest guy in the room,” Conan recalled. “When he laughed, his whole body would convulse, and he’d almost hug himself.”
He also praised his father’s zest for life: “He had an insatiable curiosity for ideas, people, and the unpredictable beauty of life. He wanted to go everywhere, meet everyone, and experience everything.”
A Family Remembered
In addition to Conan, Thomas and Ruth are survived by their sons Justin, Neal, and Luke; daughters Kate and Jane; and nine grandchildren.
Their lives were marked by incredible accomplishments, deep love, and a commitment to their family, leaving behind a legacy that will continue to inspire those who knew them.
