John Chambers (September 12, 1922 – August 25, 2001) was an American make-up artist and prosthetic makeup expert in both television and film.

He is best known for creating the pointed ears of Spock in the television series Star Trek (1966), and for his groundbreaking prosthetic make-up work on the Planet of the Apes film franchise.

[8] Chambers worked on the pilot episode of Mission Impossible and created the pointed ears worn by Leonard Nimoy's Spock in the original Star Trek television series.

[2] Some of his character creations, including Cornelius and Dr. Zaius from the Planet of the Apes series, are on display at The Science Fiction Museum in Seattle.

[12] To make the cover story believable, Chambers used actor Michael Douglas's former office during the filming of The China Syndrome (1979) at Sunset Gower Studios.

Chambers and Mendez printed fake business cards, held a film press party at a nightclub in Los Angeles, and took out advertisements in Variety and The Hollywood Reporter magazines.

[13] The rescue effort was successful, and Chambers was awarded CIA's Intelligence Medal of Merit,[1][13] but he was required to keep his involvement a secret, until the story was declassified in 1997.
