Mark W. Tiedemann (born 1954 in St. Louis, Missouri) is an American science fiction and detective fiction author. He has written novels set in Isaac Asimov's Robot universe, and within his own original universe, known as the Secantis Sequence.
Tiedemann published three short stories before 1988, in small press magazines, the most notable of which was Reveleven, published by Scott Edelman in his magazine Last Wave in 1986. Frustrated by a continued inability to break into the major magazine markets, he applied to and was accepted by Clarion Writers Workshop. In the summer of 1988, Mark attended Clarion with instructors Tim Powers, Lisa Goldstein, Samuel R. Delany, Kim Stanley Robinson, Kate Wilhelm and Damon Knight.
Within a year of Clarion, Mark began selling short stories. His first major sale was Targets, sold to Gardner Dozois, editor of Asimov's Science Fiction Magazine. Several more quickly followed.
His first novel, Compass Reach, was shortlisted for the Philip K. Dick Award. Two other novels followed, Metal of Night and Peace and Memory.
His most recently published novel, Remains, from BenBella Publishing, is separate from his Secantis universe. The novel was shortlisted for the James Tiptree Jr. Award in 2006.
