Patrick Stewart, the British actor renowned for his roles as Captain Jean-Luc Picard in *Star Trek* and Professor Charles Xavier in *X-Men*, died on Wednesday at his home in Los Angeles. He was 86.

His spokesperson, Kelly Bush Novak, confirmed he had battled Alzheimer’s disease and Lewy body dementia. In a statement, she said he was surrounded by family, friends, live music, prayers, tears, and laughter in his final moments. “His sonorous voice and unique talent will forever be synonymous with unforgettable performances in every genre,” the statement read.

Born in Mirfield, Yorkshire, in 1940 to a textile worker mother and a military father, Stewart began acting in local theater groups as a child. He joined the Royal Shakespeare Company in 1966, spending 15 years performing classical roles like Macbeth, Shylock, and Claudius. His stage work earned him a Laurence Olivier Award in 2008 for *Macbeth* and a Tony nomination in 2010.

Stewart’s global fame came with *Star Trek: The Next Generation* (1987–1994), where he played Captain Picard for 178 episodes, followed by four films. He reprised the role in *Star Trek: Picard* (2020–2023). Concurrently, he portrayed Professor Xavier in seven *X-Men* films and will appear posthumously in *Avengers: Doomsday*, set for release in December.

Knighted by Queen Elizabeth II in 2010 for his contributions to drama, Stewart was also a vocal advocate for domestic violence survivors, inspired by his own childhood. He leaves behind his wife, musician Sunny Ozell, and two children from his first marriage to actress Sheila Falconer. His family requested donations to Alzheimer’s research in his memory.

Tributes poured in from colleagues. William Shatner, the original *Star Trek* captain, called Stewart a man of “intelligence, grace, and deep humanity.” Hugh Jackman, his *X-Men* co-star, said, “I learned so much from him. I will miss you, Patrick Stewart, all of my days.” Marvel Studios praised his portrayal of Xavier as “extraordinary, intelligent, and humane,” shaping the character for generations.
