Joan Chauvin Marsden (née Rattenbury; 1922 – January 26, 2001) was a professor of zoology, chair of the zoology department at McGill University, president of the Canadian Society of Zoologists, and director of the Bellairs Institute in Barbados.^[1][2][3][4]

She studied the ecological, physiological, and neurobiological perspectives of the polychaete worm and (co-)authored more than 40 publications, at least 15 of which from her time at the Bellairs Institute.^[5]

Marsden completed her Bachelor of Science (1943) and Master of Science (1944) at McGill University.^[6] She then went on to earn a PhD at the University of California, Berkeley in 1951.^[4][6]

Marsden returned to McGill and would spend more than 60 total years at the university. Her first appointment was a role as lecturer in the department of zoology and she quickly climbed the academic ladder during a time when there were few female scientists at McGill.^[1]

Shortly after the 1954 founding of the Bellairs Institute, Marsden and fellow zoologist John Lewis were the first McGill professors to exploit the research opportunities the Caribbean institute had to offer. She traveled there almost yearly to conduct her research.^[1]

As chair of the Zoology Department, Marsden was instrumental in the creation of the Biology department through the fusion of the Departments of Zoology, Botany, and Genetics in 1969.^[1]

Marsden served as president of the Canadian Society of Zoologists from 1980 to 1981.^[2] Marsden retired from McGill in 1987. To honor her legacy and perpetuate her memory, her colleagues established the Joan Marsden Lectures in Organismal Biology.^[1]

Marsden passed away unexpectedly at the age of 78 in the Barbados.^[3]
