Anthony Clive Barwick (10 July 1934 – 18 August 1993) was a British television scriptwriter who worked extensively on series created and produced by Gerry Anderson. Barwick scripted episodes for Gerry Anderson's Supermarionation series Thunderbirds, Captain Scarlet and the Mysterons, Joe 90 and The Secret Service, as well as his live-action series UFO, The Protectors and Space: 1999. He also contributed scripts to Anderson's and Christopher Burr's Supermacromation series Terrahawks, writing under various pseudonyms for all but one episode. All of these pseudonyms ended with the suffix "-stein" in imitation of the name of the leading character, Dr Tiger Ninestein. Barwick wrote 35 of the 39 episodes of Terrahawks; "The Midas Touch", which he co-wrote with Trevor Lansdowne, is the only episode for which he used his real name. With the completion of Terrahawks, Barwick went on to script the whole of Anderson's two-part stop-motion series Dick Spanner, P.I. (for which he was credited as "Harry Bolt"). In addition to his work as a scriptwriter, Barwick also served as script editor for Captain Scarlet, Joe 90 and UFO. His other writing credits include The Persuaders!, The Pathfinders, The Professionals and Shadowchaser. Other work
