Mary Ellouise Black (September 18, 1895 – February 11, 1988), an occupational therapist, teacher, master weaver and writer, created almost single-handedly a renaissance in crafts in Nova Scotia in the 1940s and 1950s. Her best-known book, ‘’The Key to Weaving", was published in 1945 and has since run to 3 editions and numerous printings. Its clarity is without parallel, and, more than half a century later, it remains a handweaver's prime source of information.
