Elsie May Burrows (née Pearson) (14 September 1913 – 26 August 1986) was an English botanist who made significant contributions to British postwar phycology. Her primary area of research was macroalgal ecology, focusing particularly on Fucus, a genus of brown algae, and Chlorophyta, a division of the green algae. Career Burrows assumed a post as research assistant in the Department of Botany at the University of Liverpool in 1936, where she spent her career until she retired in 1973. This was hindered by the misogyny of her supervisor, John McLean Thompson. However, she was finally promoted to senior lecturer and chaired the Department of Botany in 1967 to 1968. She received her Ph.D. as an external student of the University of London in 1948 for work on the biology of Ascophyllum nodosum. Her subsequent research, often in collaboration with staff based at the Port Erin Marine Biological Station on the Isle of Man, included studies on laboratory cultivation of marine algae, including Fucus and Laminaria species, thus opening the way for experiments under controlled conditions. She also undertook fieldwork, and her studies published in 1950 with Sheila Lodge on the interrelationships between marine algae and animals was ahead of the field. A founder member of the British Phycological Society, she served as the organization's vice president from 1957 to 1958. She continued to be involved with the society, as a member of its managing committee, flora committee and its meetings until her death in 1986. In 1951, she began collecting data for her monograph on the Chlorophyta, as part of Seaweeds of the British Isles. The manuscript was completed shortly before her death and published posthumously in 1991. A number of specimens collected and identified by her for the Seaweed Mapping Scheme remain in the herbarium at the Ulster Museum. She also influenced phycology through training a number of doctoral students who went on to have significant careers including Anne Archer, Tony Chapman, Robin South and Trevor Norton.
