Dorothy Wigmore

Winnipeg, Manitoba, Canada
Dorothy Wigmore still has her early 1990s “Fresh air” enscribed brick from the Canadian Union of Public
Employees (CUPE). One of her filing cabinets has at least one-and-a-half drawers full of materials about
indoor air hazards and solutions. These days, her work includes building Corsi-Rosenthal boxes with and
for migrant farmworkers, to clean the air in their living quarters and work spaces, and writing a lot about
indoor air and other health and safety topics for the New Jersey Education Association.

A long-time occupational health specialist, Dorothy has training, skills and experience in occupational
hygiene, ergonomics, “stress” and their intersections in a wide variety of jobs and workplaces. She has
worked for unions representing education workers in the United States and Canada as a hygienist,
researcher, educator and writer and with/for other unions, governments, occupational health
centres/clinics, NGOs and universities. A pioneer of body and workplace mapping, her international
network of occupational health and safety colleagues and friends provide connections to creative and
effective health and safety activities and solutions around the world.
Dorothy is on contract with the Occupational Health Clinics for Ontario Workers (OHCOW) migrant
farmworker projects, where she learned to make the CR boxes and has prepared materials about
hazards, respirators, other pandemic protections and worker rights.
