Writer producer John D.F. Black has passed away aged 85 and the official site take a look at his life and career.
Black earned one solo teleplay while with TOS, and it was an important one: "The Naked Time," which helped establish the character of Spock and earned Black a Hugo Award nomination. He beamed back to Trek for Star Trek: The Next Generation, writing the episode "Justice" (using a pseudonym, Ralph Wills) and receiving a "Story By" credit on "The Naked Now," a follow-up to "The Naked Time." More recently, he provided commentary seen and heard on the Blu-rays, 50 Years of Star Trek and Star Trek: Inside the Roddenberry Vault.
Our condolences to Black's friends, colleagues and family.
