Eric Dane, ‘Grey’s Anatomy’ Star, Dies at 53 Following ALS Battle

Eric Dane, best known for his role as Dr. Mark Sloan, “McSteamy,” on the ABC medical drama Grey’s Anatomy, has died at the age of 53 following a battle with amyotrophic lateral sclerosis (ALS). The news was confirmed by his representative on February 19, 2026.

A Career Spanning Decades

Dane first gained recognition in the 1990s with appearances in series such as California High School, A Terribly Nice Family, and Charmed. He rose to prominence as Dr. Mark Sloan in Grey’s Anatomy, joining the cast in its second season in 2006 and remaining a main cast member until 2012. Following his departure from Grey’s Anatomy, Dane took on the lead role of Captain Tom Chandler in the apocalyptic series The Last Ship. More recently, he appeared in the HBO production Euphoria (2019), portraying the character Cal Jacobs.

ALS Diagnosis and Advocacy

Dane publicly announced his diagnosis of ALS in April 2025. Despite the challenges posed by the disease, he remained committed to raising awareness and funding for research. He was scheduled to be honored with the Dean and Kathleen Rasmussen Advocate of the Year Award at an ALS Network gala in January 2026, but had to withdraw due to the physical realities of living with ALS [1]. He continued to work on projects, including a guest role in the drama series Brilliant Minds, where he played a firefighter secretly battling ALS.

Family and Legacy

Dane is survived by his wife, Rebecca Gayheart, and their two daughters, Billie and Georgia. The family released a statement expressing their grief and highlighting Dane’s dedication to advocating for ALS awareness and research. His representatives noted that he spent his final days surrounded by loved ones [1]. Gayheart publicly supported Dane throughout his illness, detailing their journey in an article for The Cut in December 2025 [2].

Understanding ALS

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a rare neurological disorder that affects the central and peripheral nervous system. It leads to the destruction of nerves, causing muscle weakness, difficulty with swallowing and breathing, and paralysis [2]. There is currently no cure for ALS.

Final Projects

Prior to his death, Dane had announced plans to write a memoir titled Book of Days: A Memoir in Moments, sharing his reflections on life and his battle with ALS. He expressed a desire to encourage readers to appreciate every moment [1].

Eric Dane’s passing is a loss to the entertainment industry and the ALS community. His advocacy efforts will continue to inspire hope and support for those affected by this devastating disease.
