(1954-    ) US author who began to publish work of genre interest with "The Spacer Walks" in Space and Time for December 1983 as M William Tiedemann; The Gravity Box and Other Spaces (coll 2014) is a good selection of his shorter work, which ranges from Hard SF to Steampunk and fantasy. His contributions to the Isaac Asimov's Robot Mysteries Shared World sequence of Ties based on the Robot stories of Isaac Asimov, beginning with Asimov's Mirage (2000), are competent. In his own right, the Secantis Sequence beginning with Compass Reach (2001) is structured around an ideological division not uncommon in Space Opera, though well deployed here: a rigid hierarchical domain, here called the Pan Humana, where Genetic Engineering is not allowed, and Aliens are barred; and a more free-flowing adversary domain, here called the Commonwealth Republic, where aliens are welcome, and Homo sapiens increasingly diversifies in ways that are anathema to Pan Humana, where a stark Religion holds sway. In contrast to this wide-screen arena, a singleton like the Near Future Remains (2005), with much of its action restricted to a single Space Station, focuses on more personal issues – love and betrayal and death – in Tiedemann's colourful universe.
