Our hearts are happy on Marie Maynard Daly's birthday. Born #OTD in 1921, Daly pioneered research on the relationship between high cholesterol and clogged arteries, helping us understand how food and diet affect heart health. She was the first African-American woman to earn a doctorate in chemistry in the United States. . . . . . . . . . #womanscientist #womeninscience #firstwoman #highcholesterol #herstory #leadingwomen #womeninleadership #womeninstem #arteries #stemwomen #womendoingscience #shecanstem #womanintech #womenwhoscience #womenempower #thisiswhatascientistlookslike #chemistry #womeninscienceandengineering #womenintech #womenintechnology #womenshistorymonth #womenshistory #blackandstem #mariemaynarddaly
