Marie M. Daly Biography

Chemist, Scientist, Scientist(1921–2003)
Marie M. Daly is best known for being the first African-American woman to receive a Ph.D. in chemistry in the United States.


Marie M. Daly was born on April 16, 1921, in Queens, New York. 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. After completing her Ph.D. at Columbia—and becoming the first African-American woman to obtain a Ph.D. in chemistry in the United States—Daly taught and conducted research. She died in New York City on October 28, 2003.


Future chemist Marie M. Daly was born on April 16, 1921, in Queens, New York. The pioneering scientist was the first African-American woman to receive a Ph.D. in chemistry in the United States, and her groundbreaking work helped clarify how the human body works.


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 Marie's love of books—in particular those that centered on science and scientists.

Higher Education

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.

Receives Ph.D.

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.

Researcher and Activist


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.
