Margaret Hutchinson (later Rousseau) was born on November 2, 1910, in Brooklyn, New York.
Margaret Hutchinson Rousseau was born on November 2, 1910, in Brooklyn, New York. She would go on to become one of the most consequential chemical engineers of the 20th century, breaking barriers for women in a field almost entirely closed to them at the time.
Raised in an era when women were actively discouraged from pursuing engineering, Rousseau's early academic gifts in mathematics and science set her on an unconventional path. She would eventually earn degrees from Mount Holyoke College and MIT, becoming the first woman to receive a doctorate in chemical engineering from the Massachusetts Institute of Technology.
Her birth marks the starting point of a life that would intersect with some of the most urgent scientific challenges of the World War II era, particularly the industrial-scale production of penicillin, a breakthrough that saved countless lives on the battlefield and beyond. Her legacy as a pioneering woman in STEM continues to be recognized by professional societies and historians of science.
