D Ellen Swallow Richards was the first woman to earn a bachelor’s degree from Massachusetts Institute of Technology (MIT). A chemist, social activist, teacher, and first woman member of the Institute of Engineering, she believed that housekeeping was a science. As a progressive thinker at the time, she thought that women needed to learn about money matters and have up-to-date information on cleanliness and nutrition. She encouraged women from all backgrounds to get the best education possible. Ellen was born in 1842 and was brought up in Massachusetts. A graduate of Vassar College in New York, she returned to New England to attend MIT. After her marriage to Professor Robert Richards, she worked in a laboratory at MIT, examining pollution of water sources in Massachusetts. Her work led to the creation of the first food-inspection (检验) laws of that state. She was instructor at MIT from 1884 until her death in 1911. Like other progressive thinkers of the time, Ellen was worried about problems of the poor and the effect of the environment on society. She considered the environment a key factor in quality of life. Within the family, as in the world at large, science was chief in tools used to help the poor. Science could help to manage money matters, keep a home safe and clean, and improve quality of life. Food properly cooked could be tasty, nutritious, and inexpensive. Better and cheaper food could protect the health and improve the lives of working-class families. Ellen created the science of housekeeping, now called home economics, and elevated（提升）it to a serious college subject. She worked tirelessly as a national leader in developing standards, materials, and teacher training for this new field. Her publications cover many subjects—from the chemistry of cooking and cleaning to the cost of living. 57. According to the text, Ellen __________.
