The actor’s death was reported by Euronews, NPR and France 24, which all gave his age as 86. France 24 said a statement released on Thursday announced his death, but the available reporting does not identify who issued it.
Euronews reported that Stewart’s death followed what spokesperson Kelly Bush Novak described as a brief and poignant journey with Alzheimer’s disease and Lewy body dementia. That medical detail appears only in the Euronews report and is not independently established by the other supplied sources.
Stewart’s best-known screen roles made him a defining presence in two major popular franchises. He played Captain Jean-Luc Picard in Star Trek, including The Next Generation series and films, and Professor Charles Xavier in the X-Men films.
His career also had a substantial British stage foundation. France 24 described Stewart as an acclaimed actor who performed with the Royal Shakespeare Company before he moved into the Star Trek television role and later the X-Men franchise.
The available reports therefore establish a career spanning major stage work and internationally recognized film and television characters, while leaving some details of the announcement and his final illness dependent on individual-source reporting. The three outlets agree on the central fact of his death at 86.
