Steve Miller was born on July 31, 1950, in Baltimore, Maryland. He attended Franklin High School in Reisterstown, Maryland, graduating in 1968; and the University of Maryland, Baltimore County in the late 1960s and 1970s, where he was news editor and managing editor of the campus newspaper, The Retriever and founding president of the Infinity Circle, the school's first science fiction club. He served as founding Curator of the UMBC Albin O. Kuhn Library & Gallery's science fiction research collection. Miller was an active member of science fiction fandom for many years, serving as Director of Information of the Baltimore Science Fiction Society for some years, and as vice-chair of the bid committee to hold the 38th World Science Fiction Convention in Baltimore (they lost to Boston).[2][3]
Miller married Baltimore-area science fiction fan Sue Nice in 1975; they divorced in 1979. He and Sharon Lee were married in 1980. In 1988, they relocated to central Maine, living for some time in Winslow, Maine. In early 2018, they moved "into town" to nearby Waterville (on the other side of the Kennebec River).[4] Steve Miller died in Waterville on February 20, 2024, at the age of 73.[5][6]
In 1973, Miller attended the Clarion West Writers Workshop. He sold short fiction to semi-professional markets, and wrote for science fiction fanzines, before selling a short story, "Charioteer" to Amazing Stories (May 1978 issue).[7] He has since published dozens of novels and over 50 short stories, as well as book reviews, essays and other non-fiction; much (though not all) in collaboration with Lee. He has also collaborated with Lee on some non-Liaden works.[8][9]
Miller and Lee strongly oppose fan fiction written in their universe. In Lee's words:
I don't want "other people interpreting" our characters. Interpreting our characters is what Steve and I do; it's our job. Nobody else is going to get it right. This may sound rude and elitist, but honestly, it’s not easy for us to get it right sometimes, and we've been living with these characters ... for a very long time ... We built our universes, and our characters; they are our intellectual property; and they are not toys lying about some virtual sandbox for other kids to pick up and modify at their whim. Steve and I do not sanction fanfic written in our universes; any such work that exists, exists without our permission, and certainly without our support.[10]
Miller ran a small press from 1995 through 2012, specializing in chapbooks containing 2-3 short stories set in the Liaden Universe, and other settings from books by him, Sharon Lee and other authors. The works published under this imprint by Miller and Lee have been published as ebooks in editions from Baen Books following the termination of operations of SRM Publishers, Ltd.
Miller, usually with Lee, has been a Guest of Honor or Special Guest at a number of science fiction conventions, including:
SiliCon (1998); SheVaCon (2000, 2003); Albacon (2002); Balticon and MarsCon (2003); PortConME (2004, 2010); CONduit and Trinoc*coN (2004); Penguicon and COSine (2006); Stellarcon (2009); DucKon and Oasis (2010); ConQuesT and Chattacon (2012); and RavenCon (2016).[68]
