Quote: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.

Quote:“What a heartbreaking week it has been,” William Shatner, who played Captain James T. Kirk in the franchise, wrote on Instagram. “Sir Patrick Stewart was a friend, a colleague, and a magnificent actor. From the stage to the bridge of the Enterprise, he brought intelligence, grace, and a deep sense of humanity to everything he did.”
