Faces behind White Coats, Black Scientists, Connecting Past and Present Forms of Racism in Science.


Scientists study often consider their work and their institutions unbiased. After all, scientists rely on a rigorous set of experiments to test hypotheses and arrive at conclusions that inform what the rest of us know to be facts in the world.


The egregious violence used against Black people by police in the U.S. is paralleled in science, too. The Tuskegee Syphilis Study observed untreated syphilis in nearly 600 Black men for 40 years to develop a vaccine for the virus. The majority of the Black men were left untreated, creating hardships for multiple generations.


And yet history demonstrates how scientific practices have been used to justify systemic racism. Further, the exclusion of Black scientists from institutions, the failure to recognize the contributions of Black scientists, and the lack of culturally relevant scientific curricula perpetuate the underrepresentation of Black people and their perspectives in science.

Scientific discipline: Mathematician and Computer Scientist

Date of birth: September 1910

Place of birth: Morgantown, West Virginia

Date of death (if relevant): November 2008

Their main contribution(s) to science and the world: Dorothy is best known for her work as a 'Human Computer' at NACA and then NASA. 

She would make ground-breaking advancements in the proliferation of FORTRAN and made significant contributions to the U.S. Space Program. 

Brief biography:  Dorothy graduated from Beechurst High School in 1925. She would later earn her B.A. in Mathematics and then began working as a school teacher to help her family through the great depression.


After getting married and bearing children, Dorothy would simultaneously rear her children and lead a highly successful career with NACA, later NASA. She would be a lifelong advocate for racial and female equality and a committed Methodist Christian.

She would retire at the age of 60 in 1971.

Harold Amos

Scientific discipline: Professor and Microbiologist

Date of birth: 1918

Place of birth: Pennsauken, New Jersey

Date of death (if relevant): 2003

Their main contribution(s) to science and the world: Harold Amos was the first African American Microbiologist and the first to become the department chair of Harvard Medical School. 

Harold made various high profile discoveries in his discipline including the finding of the 5-methylcytosine in the E. coli RNA and spearheading research into the use of bacterial RNA to program the synthesis of higher cell proteins, insulin, etc. 

Harold was a well-respected educator too and often cited teaching as one of his many passions. he would receive many awards throughout his career including the first Charles Drew World Medical Prize from Harvard University in 1989, an Honoris Causa doctoral degree from Harvard University in 1996, the Centennial Medal of the Harvard Graduate School of Arts and Sciences in 2000, and the National Academy of Science’ highest honor, the Public Welfare Medal in 1995.


Brief biography: Harold was born in Pennsauken, New Jersey in 1918. His parents had close connections with the Quakers who would often gift books to the Amos family - one of which was the biography of Louis Pasteur. 

This would spark an interest that would lead to a lifetime fascination into the microscopic world. Harold would serve in France during the Second World War. 

After returning home he began his studies into the biological and medical sciences in 1946. Once he'd collected various degrees and a Ph.D. he returned to France under a scholarship to the Pasteur Institute. 

He then returned to the U.S. to begin a lifelong career at Harvard University - where he would study and teach for the next 50 years. 

St. Elmo Brady

Scientific discipline: Chemist

Date of birth: 1884

Place of birth: Kentucky, Alabama

Date of death (if relevant): 1966

Their main contribution(s) to science and the world:

The idea that Black people’s bodies are expendable is what led to the implementation of the Tuskegee Syphilis Study in the first place and has not escaped the minds of scientists today. For example, two French scientists casually suggested that experimentation to determine the effectiveness of a tuberculosis vaccine against Covid-19 should take place in Africa. According to one of the researchers:


“If I can be provocative, shouldn’t we be doing this study in Africa, where there are no masks, no treatments, no resuscitation? A bit like as it is done elsewhere for some studies on AIDS. In prostitutes, we try things because we know that they are highly exposed and that they do not protect themselves.”


Their casual suggestion to experiment with populations on the African continent demonstrates how Black people have and continue to be violated by scientific studies.

Brief biography: Born as a freeman he would go on to become one the United States most accomplished intellectuals. Interestingly his heritage included African Royalty.

In time he would self-teach himself many disciplines of STEM including his mastery of mathematics and astronomy.

He would later send a copy of his first almanac to Thomas Jefferson (U.S. Secretary of State) with other documents explaining his position on racial equality.

Date of birth: 1864

Place of birth: Missouri

Date of death (if relevant): January 1943

Their main contribution(s) to science and the world: George almost single-handily built the peanut industry in the United States. His research would help the impoverished farming industry of southeastern Alabama by educating them in crop rotation and plant fertilization.

He is, however, most famous for his work on peanuts that earned him the title of 'peanut man' for his introduction of the potential of it as a foodstuff. George also discovered the nutritional benefit of sweet potatoes. 

His discoveries earned him several patents and the 1923 Spingarn Medal. He was also posthumously inducted into the National Inventors Hall of Fame.

Brief biography: George was born into slavery during the American Civil War. He would later earn his freedom, receive a Bachelor's degree in Agricultural Science in 1894 and a master's in 1896.

Date of death (if relevant): December 1916

Their main contribution(s) to science and the world: Alice is best known for her successful treatment of those suffering from Hansen's Disease, aka leprosy. This would prove to be the world's first working treatment for this debilitating disease. 

Tragically she would die very young at the age of 23 and would never receive recognition for her achievements in her lifetime. 

Brief biography: Ball was born as the granddaughter of the, then, famed daguerreotypist James Presley Ball.  Her father was also a promising lawyer. 

Alice Ball graduated from the University of Washington with two degrees in Pharmaceutical Chemistry in 1912 and a pharmacy in 1914.

Alice would later earn her master's in Chemistry from the University of Hawaii in 1915 and would go on t become the first woman to teach Chemistry when she was 23 years old.
