Marianne Ackerman was born in Belleville, Ontario and grew up on a farm in Prince Edward County.^[1] She received a Bachelor of Arts in Political Science (Honours) from Carleton University in 1976.^{[citation needed]} She spent a year at the Sorbonne in Paris studying French language and culture before receiving a Master of Arts in Drama from the University of Toronto in 1981.^[2]

From the early 1980s, Ackerman lived in Montreal, where she worked as a freelance journalist and as theatre critic for the Montreal Gazette, winning the Nathan Cohen Award for theatre criticism.^[3]

In the late 1980s, she founded a bilingual theatre company, Theatre 1774, which staged her plays L'Affaire Tartuffe, Woman by a Window, Céleste and Blue Valentine, as well as her adaptations of August Strindberg's Miss Julie and William Shakespeare's Measure for Measure. The company also staged Echo, a play developed by Robert Lepage from Ann Diamond's book of poetry, A Nun's Story, co-produced with Theatre Passe Muraille. She and Lepage collaborated on Alienouidet, a play about the actor Edmund Kean in Canada, directed by Lepage at the NAC. Venus of Dublin, a distilled version of the story, premiered at the Centaur Theatre in 2000, and has since been produced several times.^{[citation needed]}
