Marie Maynard Daly (April 16, 1921 – October 28, 2003) was an American biochemist.
She was the first Black American woman in the United States to earn a Ph.D.
in chemistry (awarded by Columbia University in 1947).
Daly made important contributions in four areas of research: the chemistry of histones, protein synthesis, the relationships between cholesterol and hypertension, and creatine's uptake by muscle cells.Daly's father, Ivan C.
Daly, had immigrated from the British West Indies, found work as a postal clerk and eventually married Helen Page of Washington, D.C.
They lived in New York City, and Marie was born and raised in Corona, Queens.
She often visited her maternal grandparents in Washington, where she was able to read about scientists and their achievements in her grandfather's extensive library.
She was especially impressed by Paul de Kruif’s The Microbe Hunters, a work which partially influenced her decision to become a scientist.Daly's interest in science was also influenced by her father, who had attended Cornell University with intentions of becoming a chemist, but had been unable to complete his education due to a lack of funds.
His daughter continued her father's legacy by majoring in chemistry.
Many years later, she started a Queens College scholarship fund in his honor to assist minority students majoring in chemistry or physics.
