Dr. Marie Daly

Biochemist


Dr. Marie Daly was a biochemist and the first African American woman to earn a Ph.D. in chemistry in the United States. She made vital contributions in four areas of research: the chemistry of histones, protein synthesis, the relationships between cholesterol and hypertension, and creatine uptake by muscle cells.



Anna Mani

Meteorologist


Anna Mani was an Indian meteorologist who contributed significantly to the understanding of solar radiation, ozone and wind energy by developing a wide range of measurement tools. One of India’s pioneering female scientists, Mani excelled in the male-dominated area of meteorology and became the Deputy Director-General of the India Meteorological Department.
