John Chambers was an American make-up artist and prosthetic makeup expert in both television and film. He received an Academy Honorary Award from the Academy of Motion Picture Arts and Sciences in 1968. 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.

Prosthetic makeup, which may also be referred to as special make-up effects or FX prosthesis, is the process of using prosthetic sculpting, molding, and casting techniques to create advanced cosmetic effects. Prosthetic makeup draws a straight lineage from the Stagecraft of theater and can be observed at the birth of science fiction cinema with Le Voyage dans La Lune, a 1902 French adventure short film directed by pioneer of special effects Georges Méliès.
