Patrick Stewart, the classically trained actor who added Shakespearean gravitas to the “Star Trek” and “X-Men” franchises, has died. He was 86.Stewart died Wednesday in Los Angeles, following “a brief and poignant journey” with Alzheimer’s disease and Lewy Body Dementia, spokesperson Kelly Bush Novak said. Stewart’s diagnoses had not been previously disclosed.“We lost one of the greats of stage and screen today,” Hugh Jackman, a frequent Stewart co-star in the “X-Men” universe, said on social media. “And, in my book, a tremendous friend and man. I learned so much from him. I will miss you, Patrick Stewart, all of my days.”While best known as Professor Charles Xavier and Captain Jean-Luc Picard from the “X-Men” and “Star Trek: The Next Generation” series and films, respectively, Stewart spent more of his career onstage than in the X-Mansion or on the USS Enterprise.Besides playing everyone from Claudius to Macbeth, he often performed a one-man rendition of “A Christmas Carol” and did West End and Broadway runs of Harold Pinter’s “No Man’s Land” and Samuel Beckett’s “Waiting for Godot” in repertory with buddy Ian McKellen.He achieved some of the best reviews of his career when he finally tackled Macbeth for the first time. The production, under the direction of Rupert Goold, debuted in May 2007 at England’s Chichester Festival Theatre, switched to London’s West End and then moved to the Brooklyn Academy of Music before transferring to Broadway in 2008.Stewart’s performance earned him his sole Tony Award nomination. The Times of London said his Macbeth was “an enthralling creation of frailty, appetite, egotism and grim humor.” The Daily Telegraph said he had turned in “a truly great performance” and The New York Times said it was “a must-see.”Story continues below this ad“Nearly 50 years I’ve waited,” Stewart told The Associated Press in 2008. “I learned it when I was 14. I memorized all the soliloquies just because I thought they were great. And they stuck, so I didn’t have to learn those bits of the play, which is a blessing, because learning lines has now become the one curse of this job.”Starship commander grew up without a toiletRaised in Mirfield in Yorkshire, a working-class corner of northern England, the future 24th- century commander of a starship grew up without a bathroom in his house.Stewart joined an amateur drama group at 12 and memorized Shakespeare for fun as a teen. He won a scholarship to the Bristol Old Vic Theatre School, launching a career as a character actor.He had been bald since he was 19 — alopecia runs in his family.Story continues below this adHis father, a former regimental sergeant major in the British Army, was prone to outbursts of “repeated violence against my mother,” as Stewart wrote in a newspaper piece. “Violence is always a choice a man makes and he alone is responsible for it.”In his memoir, “Making It So,” Stewart wrote about how he and his older brother Trevor braced for the nights when their dad came home drunk and angry, and attacked their mother. “Sometimes it was with an open hand, other times a closed fist. Always he aimed for her head.”The son would later become a patron for Refuge, an organization that provides shelter for domestic abuse victims.
