Wah Ming Chang was an American designer, sculptor, and artist. With the encouragement of his adoptive father, James Blanding Sloan, he began exhibiting his prints and watercolors at the age of seven to highly favorable reviews. Chang worked with Sloan on several theatre productions and in the 1940s, they briefly created their own studio to produce films. He is known later in life for his sculpture and the props he designed for Star Trek: The Original Series, including the tricorder and communicator.

Star Trek is an American science fiction television series created by Gene Roddenberry that follows the adventures of the starship USS Enterprise (NCC-1701) and its crew. It acquired the retronym of Star Trek: The Original Series (TOS) to distinguish the show within the media franchise that it began.
