Ellen H. (Ellen Henrietta) Richards

Born in 1842, Ellen H. Richards was an American chemist, teacher, and reformer whose career opened new ground for women in science. She studied at Vassar and later became the first woman admitted to the Massachusetts Institute of Technology, where she also worked in chemistry and taught for many years.

Richards believed science should improve daily life. She became known for her research on water quality and sanitation, and she helped promote what she called “oekology,” a way of thinking about the relationship between people and their surroundings. Her writing and public work also helped shape the early home economics movement, bringing chemistry, nutrition, and public health into schools and homes.

She died in 1911, but her influence lasted well beyond her lifetime. Today she is remembered not only for breaking barriers in higher education and science, but also for insisting that careful research could make ordinary life safer, healthier, and better organized.
