Jacobs was born as Marja Schröder in the Netherlands. She
lived in Amersfoort, a medium-size city in the heart of the country.
Her family became actively involved in the concealment and care
of Jews sought by the Germans in occupied Holland.
In the mid-fifties she came to North America with her young husband
Peter Moens. Since then she has lived in New York and Toronto,
borne three sons and two daughters, and obtained a BA in mathematics
and an MA in English.
After this, for many years, she ran The Axle-tree Coffee House
in downtown Toronto, where poets and musicians met. She published
a magazine, Poetry Toronto, for about a decade, wrote three books
of poetry, and edited several anthologies. She was a member of
the team of readers which screened the entries for the CBC Literary
Competition conducted by Robert Weaver for over twenty years.
With her friend and fellow-poet Heather Cadsby, she founded the
publishing house of Wolsak and Wynn in 1982, of which she is presently
the publisher and sole proprietor. She lives in the Beaches area
of Toronto with two handsome cats, Soot and Il Tigretto.
