Character actor Peter Vaughan, who played the wise healer-scholar Maester Aemon on HBO's Game of Thrones, died Tuesday at age 93, surrounded by family, agent Sally Long-Innes says.

Vaughan’s face — if not his name — was familiar to generations of television viewers in Britain and around the world. His best-known roles included criminal Harry Grout in 1970s prison sitcom Porridge.

His film appearances included The Naked Runner, opposite Frank Sinatra, and The French Lieutenant’s Woman.

Born Peter Ohm in the central England county of Shropshire, Vaughan was married first to the late actress Billie Whitelaw, and then to Lillias Walker, who survives him.
