Born in Toronto in 1938, David Helwig attended the University of Toronto and the University of Liverpool. His first stories were published in Canadian Forum and The Montrealer while he was still an undergraduate. He then went on to teach at Queen's University. He worked in summer stock with the Straw Hat Players, mostly as a business manager and technician, rubbing elbows with such actors as Gordon Pinsent, Jackie Burroughs and Timothy Findley.
While at Queen's University, Helwig did some informal teaching in Collin's Bay Penitentiary and subsequently wrote A Book About Billie with a former inmate.
Helwig has also served as literary manager of CBC Television Drama, working under John Hirsch, supervising the work of story editors and the department's relations with writers.
In 1980, he gave up teaching and became a full-time freelance writer. He has done a wide range of writing - fiction, poetry, essays - authoring more than twenty books. Helwig is also the founder and long-time editor of the Best Canadian Stories annual.
David Helwig lives on Prince Edward Island in the village of Eldon. He indulges his passion for vocal music by singing with choirs in Montreal, Kingston, and Charlottetown. He has appeared as bass soloist in Handel's Messiah, Bach's St Matthew Passion and Mozart's Requiem.
