Inorganic Plant Poisons and Stimulants

Winifred Elsie Brenchley

Winifred Elsie Brenchley OBE, DSc (Lond), FLS, FRES (1883–1953), an agricultural botanist who worked at the Rothamsted Research Station. Along with Katherine Warington, she demonstrated the role of boron as an essential micronutrient for plants. She was the first woman in the UK to break into the male-dominated sphere of agricultural science. She has been described as "perhaps Britain's leading authority on weeds in the early twentieth century".
