British actor, writer, and artist Olaf Pooley died last Tuesday in Los Angeles at the age of 101, his granddaughter Olivia Holland-Rose has confirmed.

Pooley’s family told that he passed away due to congestive heart failure, and that he “managed to preserve his independence and dignity to the end, which is what he wanted.”

Pooley was the oldest actor to have appeared in both the Star Trek and Doctor Who franchises, as the Cleric in the 2000 Star Trek: Voyager episode “Blink of an Eye” and as Professor Stahlman in the 1970 Doctor Who serial “Inferno.”

Pooley also developed an impressive theatrical résumé, having played Chorley Bannister in the original 1947 production of Noel Coward’s Peace in Our Time on London’s West End in addition to roles in Othello and The Tempest.

In the 1980s, Pooley moved from England to the United States, where he devoted his creative energies to painting and was an artist in residence at the Santa Monica Art Studios. Last year, on his 100th birthday, CBS News interviewed Pooley about his art.

Pooley is survived by his son Seyton, daughter Kirstie, and four grandchildren. Holland-Rose has tweeted in her grandfather’s memory.
