Katherine Short
Katherine Hartley Short was Martin Short and Nancy Dolman’s first adopted child. She was born in December 1983. She graduated from New York University in 2006 and obtained her master’s degree from the University of Southern California School of Social Work in 2010. She was a licensed clinical social worker.
Katherine reportedly had a service dog to assist her in the years prior to her death. In her since-deleted professional website, she shared a photo and bio of her service dog, Joni, named after singer Joni Mitchell.
“Joni is my incredible service dog, who has been assisting me with my own struggles with mental illness for the past 5 years,” the website read. “Joni will often be in the office with me, cuddled up on her bed,” Katherine continued. “She is an absolute sweetheart and just LOVES people, so don’t be surprised if she greets you with a smile, a wagging tail…and maybe even a kiss.”
A rep for Martin Short released a statement about Katherine’s death on Feb. 24, 2026. “It is with profound grief that we confirm the passing of Katherine Hartley Short,” the statement read. “The Short family is devastated by this loss, and asks for privacy at this time. Katherine was beloved by all and will be remembered for the light and joy she brought into the world.”
