Dr. Marie M. Daly

Marie M. Daly was an American biochemist. She was raised in an education-oriented family, and Daly quickly received her B.S. and M.S. in chemistry at Queens College and New York University, respectively. After completing her Ph.D. at Columbia University — and becoming the first African American woman to obtain a Ph.D. in chemistry in the United States — Daly taught and conducted research. Daly’s groundbreaking work helped clarify how the human body works. She died in New York City on October 28, 2003.
Daly was born on April 16, 1921, in Queens, New York. Daly came from a family that believed strongly in the power of education. Her father, Ivan C. Daly, had emigrated from the West Indies as a young man and enrolled at Cornell University to study chemistry. A lack of money blocked his path, however, and he was forced to quit college, instead returning to New York City where he found work as a postal clerk.

Daly’s mother, Helen, grew up in Washington, D.C., and came from a family of readers. She spent long hours reading to her daughter and fostered Daly’s love of books — in particular, those that centered on science and scientists.

After graduating from Hunter College High School, an all-girls institution in New York City, Daly attended Queens College in Flushing, New York, choosing to live at home in order to save money.

Daly graduated with honors in 1942, and to get around the fact that she didn’t have much money for graduate school, landed work as a lab assistant at her old college as well as a hard-earned fellowship. Both were instrumental in helping her to cover the costs of getting a graduate degree in chemistry from New York University.

Daly didn’t waste time in completing her studies. She finished her master’s degree in just a year and then, in 1944, enrolled at Columbia University as a doctoral student. Aided by her own ambition and intelligence, Daly was further helped by timing. World War II was at its peak, and employers were looking for women to fill the jobs left by the scores of men who’d been sent overseas to fight. In addition, Columbia’s chemistry program was being led by Dr. Mary L. Caldwell, a renowned scientist who helped blaze new trails for women in chemistry throughout her career.

At Columbia, Daly took to the lab, studying how the body’s chemicals help digest food. She finished her doctorate — unknowingly making history as the first female African American to receive a Ph.D. in chemistry in the United States — in 1947. Fascinated by the human body’s complicated inner workings, Daly landed a grant in 1948 from the American Cancer Society. This was the start of a seven-year research program at the Rockefeller Institute of Medicine, where Daly examined how proteins are constructed in the body.

In 1955, Daly returned to Columbia, working closely with Dr. Quentin B. Deming on the causes of heart attacks. Their groundbreaking work, which was later relocated to the Albert Einstein College of Medicine at Yeshiva University in New York, disclosed the relationship between high cholesterol and clogged arteries. That work opened up a new understanding of how foods and diet can affect the health of the heart and the circulatory system.

In addition to her research work at Einstein, Daly also taught biochemistry courses. Recognizing the importance of her own career path, Daly championed efforts to get students of color enrolled in medical schools and graduate science programs. In 1988, she started a scholarship, in honor of her father, for minority students who want to study science at Queens College.
Daly retired from Albert Einstein College in 1986. Her many honors included induction into Phi Beta Kappa as well as being tapped as a fellow of the American Association for the Advancement of Science.

Daly, who married Vincent Clark in 1961 and whose full married name was Marie Maynard Daly Clark, died in New York City on October 28, 2003.
