9 Black chemists you should know about

These inventors, educators, and unsung heroes changed lives through their work in chemistry

by Megha Satyanarayana
February 27, 2019


UPDATE: This story was updated on Feb. 21, 2020, to include profiles of St. Elmo Brady, Mary Elliott Hill, and Robert Henry Lawrence Jr.

When transplant surgeon Clive O. Callender of Howard University was going to college in the 1950s, it was common to major in chemistry as a means to get into medical school. And Callender was no different. At Hunter College, he toiled through general and organic chemistry courses with the goal of one day becoming a medical missionary.

At the time, Callender says the achievements of Black scientists were rarely celebrated. He learned about only one chemist who looked like him: George Washington Carver.

“Nothing was ever talked about that ever had to do with people of color,” he says. “Whatever role models you got, you got in your community.”

As a doctor, Callender led one of the largest pushes in the nation to improve organ-donation rates within minority groups. Looking back on his life, Callender credits the role models he had, as well as his own determination and religious beliefs, as critical in making him the leader he is today. He thinks that it is important for young students to see and learn about Black ingenuity in the generations before them.

“It’s critical to learn about them,” he says, because it reinforces aspiration. “Their unreachable stars become reachable.”

In celebration of Black History Month, C&EN is profiling nine Black chemists who made contributions to a wide range of disciplines. This list is not comprehensive and is focused on scientists who are no longer alive. We want to continue to add to this list and we want to hear from you: Who are Black chemists, living or dead, whose work or life story inspires you? Comment below to send us your suggestions.

Alice Ball

Around the turn of the 20th century, leprosy was a major public health concern in Hawaii. Alice Ball was a chemistry instructor at the College of Hawaii, which would become the University of Hawaii. She had earned a master’s degree in chemistry from the institution, looking for active components in a medicinal plant, the kava root. Ball was the first woman and first Black woman to earn a chemistry degree at the university, as well as to become an instructor.

In 1916, Harry Hollmann, a doctor at Kalihi Hospital who was treating people with leprosy, asked Ball to help him determine the active ingredients in chaulmoogra, a plant that had been used with some success to treat the disease. Hollmann was looking to isolate something concentrated and injectable, and in one year, Ball had figured out how to fractionate the active oil, allowing her to solubilize it (Arch. Derm. Syphilol. 1922, DOI: 10.1001/archderm.1922.02350260097010).

Ball died suddenly, at the age of 24, possibly of accidental chlorine poisoning in a laboratory. Her work was taken up by a male scientist who tried to take credit for her discoveries. Chaulmoogra injections based on Ball’s work became a standard treatment for leprosy until the 1940s. In 2000, Hawaii Lieutenant Governor Mazie Hirono named Feb. 29 “Alice Ball Day.”


St. Elmo Brady

St. Elmo Brady

In 1916, St. Elmo Brady, born in Louisville, Kentucky, became the first African American to earn a PhD in chemistry. He did his graduate work at the University of Illinois Urbana-Champaign, and his research focused on how the acidity of carboxylic acids changed based on the addition of different chemical groups. He taught for several years at what would eventually be called Tuskegee University and eventually became the chair of the chemistry department at Howard University.

Several years later, Brady returned to Fisk University, where he had earned his undergraduate degree, to lead its chemistry department. He took over from another noted Black chemist, Thomas W. Talley.

At Fisk, Brady created the nation’s first graduate program in chemistry at a historically Black college and eventually did the same at three other universities. In 2019, the American Chemical Society designated the University of Illinois Urbana-Champaign, Fisk University, Tuskegee University, Howard University, and Tougaloo College National Historic Chemical Landmarks because of the work that Brady accomplished at those institutions. He died in 1966.


Lloyd Noel Ferguson

Lloyd Ferguson

When he was young, Lloyd Noel Ferguson was a literal backyard chemist, inventing a moth repellent and a spot remover in the yard behind the Oakland home where he grew up. In 1943, he became the first Black person to earn a Ph.D. at the University of California, Berkeley. He worked on a defense project, creating products that might release oxygen for use in submarines.

Eventually Ferguson switched coasts, moving to Howard University to teach and lead that school’s chemistry program. As a researcher, he studied several topics, including the chemistry of taste. He was part of the team that created Howard’s chemistry doctoral program, the first at any historic Black college or university. Ferguson was relentless in creating opportunities for Black people interested in chemistry and biochemistry and received a Guggenheim Fellowship. He was one of the cofounders of NOBCChE, the National Organization for the Professional Advancement of Black Chemists & Chemical Engineers. The organization named an award after him that reflected his passion for bringing up the ranks of young Black chemists—the Lloyd N. Ferguson Young Scientist Award for Excellence in Research. He died in 2011.


Bettye Washington Greene

Bettye Washington Greene

In 1965, in the years before riots over civil rights engulfed parts of Detroit, Bettye Washington Greene was putting the finishing touches on her Ph.D. in physical chemistry from Wayne State University. Her thesis focused on how particles distribute themselves in emulsions, and this research served her well. Later that year, Bettye Washington Greene became the first Black woman to work for Dow Chemical.

While at Dow, she worked on developing colloids and on ways to improve latex. She published several papers related to work in developing polymers, including studying different properties that lend to the redispersement of latex.

Among Greene’s many accomplishments are several patents related to latex, including a latex-based adhesive using a carboxylic acid copolymerizing agent, and latex polymers with phosphates used as coatings. Greene died in 1995.


Walter Lincoln Hawkins

Walter Lincoln Hawkins

The cables used for telephone lines need to be protected from the sun’s rays, water, and heat, among other things. Before the 1950s, these cables had protective coatings made from either toxic lead or plastics, which, at the time, were prone to rapid degradation via oxidation.

Enter Walter Lincoln Hawkins, a chemist at Bell Laboratories and the company’s first Black employee in a technical position. He and a partner developed a cable sheath made of a then-new class of thioether compounds and carbon black, combined with polyethylene. The work improved the lifespan of telecommunication cables to up to 70 years and led to the expansion of telecommunications all over the world. This sheath was one of dozens of products patented by Hawkins in his lifetime. He eventually became the director of Bell’s research laboratory and was inducted into the National Inventor’s Hall of Fame.

Hawkins believed strongly in mentoring minority students, leading a project by the American Chemical Society to promote chemistry as a subject and a profession. In 1992, President George H. W. Bush awarded him the National Medal of Technology & Innovation, in part for his work in helping rural communities establish telephone communications. He died just two months later.


Alma Levant Hayden

Alma Levant Hayden

In 1963, two doctors named Stevan Durovic and Andrew C. Ivy were treating cancer patients with krebiozen, a compound they called a cure for the disease.

Except that it wasn’t, and Alma Levant Hayden, then a scientist at the National Institute of Arthritis and Metabolic Diseases, showed the world why. After federal researchers coaxed the tiniest samples from the doctor and his partner, Hayden analyzed krebiozen. The results were stunning. This compound being touted as a cancer cure was nothing more than creatine, a molecule readily available in our diets.

Hayden was among the first federal scientists of color, working at what would become the National Institutes of Health and then the Food and Drug Administration. She specialized in using spectrometry to detect steroids. At a career forum for young women in 1962, Hayden told the mostly high school attendees, “Always try to do the very best and to be the very best in whatever group you are working with.” She died in 1967.

Mary Elliott Hill

Mary Elliott Hill

Mary Elliott Hill was a chemist and teacher who worked alongside her husband, Carl Hill, for many years in the mid-1900s. The duo specialized in plastics, using Grignard reactions to form ketenes, highly reactive compounds used in the formation of esters, amides, and other challenging compounds. Hill was an analytical chemist, designing spectroscopic methods and developing ways to track the progress of the reactions based on solubility.

Hill was born in 1907 in South Mills, South Carolina. She earned a bachelor’s degree in chemistry in 1929 from what would eventually be called Virginia State University. Throughout her career, she taught high school– and college-level chemistry. In 1951, she became the head of the chemistry department at Tennessee State University, eventually leaving to become a professor at Kentucky State College when her husband was named the school’s president.


Hill instituted student chapters of the American Chemical Society at some of the historically Black colleges and universities where she taught. Many of her students became chemistry professors, and she won awards for her teaching. In the 1960s, she observed that more women were becoming interested in science, but they lost interest because of the realities of research life at that time. Hill died in 1969.

Robert Henry Lawrence Jr.

Robert Henry Lawrence Jr.

Robert Henry Lawrence Jr. was a chemist by training, but he was also the first African American astronaut. Lawrence was born in Chicago in 1935. After graduating from Bradley University with a chemistry degree, he joined the United States Air Force, eventually becoming a test pilot.

Soon after, the Air Force selected him to become an astronaut to work on low-orbit intelligence missions. This program was the precursor to the NASA’s space shuttle program. During his training, Lawrence also got a PhD in physical chemistry from the Ohio State University.

Lawrence never made it into space. In 1967, he died during a training flight at Edwards Air Force Base. He had completed about 2,500 hours of flight time in his short career. Bradley University named a scholarship in Lawrence’s honor, and a school in Chicago was also named for him. On Feb. 14, 2020, a shuttle bearing Lawrence’s name embarked for the International Space Station, carrying, among other things, supplies for scientific research.

Samuel P. Massie

Samuel P. Massie

At the height of the Manhattan Project, Samuel P. Massie was trying to figure out how to turn uranium isotopes into liquids for use in a bomb. Before joining the project, he had gone to Iowa State University to get a Ph.D. in organic chemistry. He was not allowed to live on campus or work in the same labs as white students. After being denied a draft deferment, he withdrew from the Ph.D. program and took a position working on nuclear chemistry for the Manhattan Project.

Massie eventually got his Ph.D. from Iowa State University and then worked on finding new antimicrobial compounds. In 1982, he patented an antibiotic for treating gonorrhea. In his career, he also focused on education—teaching chemistry and taking an appointment at the National Science Foundation to shape science education across the nation. In 1966, President Lyndon B. Johnson chose him to teach chemistry at the US Naval Academy, making him the first Black person to do so. Many years later, he chaired the department, becoming the first Black person to hold that position.

Massie was always a high achiever, graduating high school at 13 and college at 18. One of his Manhattan Project contemporaries was another accomplished Black scientist named Lloyd Albert Quarterman. Massie died in 2005.

Thanks for the suggestion. We will add him.
A. N. Naporano (February 27, 2020 8:36 PM)
I agree. Dr. Julian should be included here. Perhaps next time. He has been a role model for me. I admire his courage the face of extreme prejudice. Please let me refer you to this article that had appeared in an ACS publication before.

Ralph Whitney (June 4, 2020 10:40 AM)
As an additional comment about Percy Lavon Julian, PBS did a very good docu-drama on his career and life that is well worth watching. It is called "Forgotten Genius" (2 hr).
Hamdy Khalil (June 4, 2020 12:02 PM)
I agree with Professor Ralph Whitney. The documentary is worth watching.
Shankar (February 26, 2020 10:35 AM)
May I suggest to you the name of Prof. Bertram Fraser-Reid, a great sugar chemist missing from your list.
Megha Satyanarayana (February 27, 2020 2:55 PM)
Thanks for the suggestion. I'll take a look.
Hamdy Khalil (June 4, 2020 12:05 PM)
I have know Professor Fraser-Reid when he was at the University of Waterloo. Great Scientist indeed.

May I suggest to C&E News and, you the name of Prof. Bertram Fraser-Reid, a great carbohydrate chemist missing from your list.
Jeff Hansen (February 26, 2020 10:37 AM)
Hard for me to believe that Percy Julian is not included here. This year marks the 100th anniversary of his graduation from DePauw University. I can provide information about him if you want.
Mervyn Israel (February 26, 2020 11:03 AM)
Henry Hill, who was the first black president of ACS, also deserves mention.
Ralph Whitney (February 26, 2020 11:05 AM)
I'm somewhat surprised that Percy Lavon Julian isn't on this list (yet).I used to enjoy lecturing about his work on producing steroidal hormones from plant sterols. He made many other contributions to industrial organic chemistry as well.
David Lide (February 26, 2020 11:11 AM)
An important addition is Dolphus Milligan (1928-1973), who pioneered the use of low-temperature matrix isolation techniques to determine the structure of transient free radicals and other unstable molecules at the National Bureau of Standards (now National Institute of Standards and Technology). See Wikipedia and the references there for a summary of his contributions and honors.
Megha Satyanarayana (February 27, 2020 2:56 PM)
Thanks. I'll check it out.
Chris Nawrat (February 26, 2020 11:28 AM)
Percy Lavon Julian, legendary steroid researcher and the first black chemist (and second black person) to be admitted to the National Academy of Sciences seems like an obvious omission.
Pete Shapland (February 26, 2020 11:34 AM)
Great article! I have always been impressed by the steroid research of Percy Julian. He was working around the time of Russell Marker and pre-dated the great work by Djerasi at Syntex but gets very little recognition. He was a true great of steroid chemistry too!
Joseph Bryant (February 26, 2020 11:43 AM)
Thanks, this is great, I will copy and share with my kids and grand kids.
Vince Mathews (February 26, 2020 12:21 PM)
What about the inclusion of Dr. Percy Julian? A a pioneer in the chemical synthesis of medicinal drugs such as cortisone, steroids and birth control pill.
David M. Manuta. Ph.D., FAIC (February 26, 2020 12:34 PM)
Thank you for sharing these fascinating vignettes on truly outstanding men and women in our field. The stories of these special men and women reveal inspiration and positive unifying thoughts at a time when these connections are truly needed..

Marie M. Daly 4/16/21 dob 10/28/03 dod (my Nana) She is best known for being the first African-American woman to receive a PhD in chemistry in the United States. She received her BS and MS in chemistry at Queens College and New York university then completed her PhD at Columbia University. Her groundbreaking work clarified how the human body works. She was five Beta Kappa and a fellow of the American Association for the advancement of science. She retired from Albert Einstein college in 1986. She also taught at Howard university.
Megha Satyanarayana (February 27, 2020 2:57 PM)
Thank you, Carly. If you have any specific information outside of what's available publicly, please email me at I'd be happy to check it out for a future update.
Rob Schmidt (February 26, 2020 2:20 PM)
No mention of Percy Julian? He definitely should be added to the list. He was one of the first African-Americans to receive a Ph.D. in chemistry (in 1931, although he had to go to the University of Vienna to do it, due to the racial barriers in the US at that time.) Julian had a remarkable career, and was the subject of the excellent PBS NOVA episode "Forgotten Genius".
Gary Patterson (February 26, 2020 3:08 PM)
Linc Hawkins was indeed both a great scientist/technologist and a warm colleague.
Bell Labs was fortunate to have him on staff.
Alex Polykarpov (February 26, 2020 3:42 PM)
I would mention Percy Julian (also has a page in Wikipedia). I learned of his name shortly after I started to work for AkzoNobel at the Glidden R&D Center in Strongsville, OH. His name was still proudly mentioned there many years after his departure.
Diana Graham (February 26, 2020 4:23 PM)
Please consider Dr. Charles Drew who among other things figured out how to process plasma so that it could be stored and shipped to Europe during WWII. He was also the first director of the American Red Cross Blood Bank. His best biography is on the ACS website.
Erin Creel (February 26, 2020 5:30 PM)
Is there a typo in the St. Elmo Brady section? There is a reference to someone named Fisk in the second to last sentence, but I'm guessing the person that should be referenced is Brady.
Megha Satyanarayana (February 27, 2020 2:59 PM)
Thanks for the catch. We'll get it fixed.
(February 26, 2020 7:34 PM)
I'd suggest adding Percy Lavon Julian, a pioneer in the synthesis of certain pharmaceuticals, to future lists! Thanks for putting this together
David Krevor (February 26, 2020 8:21 PM)
I've been inspired by the work of both Percy L. Julian and William A. Hinton. Both did very fine chemistry, with important applications; and both overcame significant racism to make their contributions.
Megha Satyanarayana (February 27, 2020 3:00 PM)
Thanks for the suggestions. Megha
Dr. Mary L. Moller (February 27, 2020 12:09 AM)
I knew Betty Greene when we were both chemistry graduate students at Wayne State University . i am pleased to read about her contributions and that she was recognized by the ACS. I remember her fondly. I would appreciate it if you could pass my comment to her family. My home is in New York. Thank you.
Megha Satyanarayana (February 27, 2020 3:01 PM)
Thank you, Dr. Moller, I will do my best to try and find them.
Delvis Dore (February 27, 2020 1:46 PM)
I was pleased to see Dr. Robert Lawrence mentioned, as several years ago i was the Robert Lawrence scholar at Bradley Univ. as an undergraduate. It is worth mentioning that I then attended Illinois State University, where chemistry classes are taught in Julian Hall, named after the black chemist Percy Julian, widely regarded for his work with phytochemicals
Patrick Dansette (March 2, 2020 5:40 AM)
I fully aggree with the mention of Percy Julian.
I heard him onec at NIH around 1974.
Angela Edwards (March 2, 2020 7:13 PM)
What a fantastic article. I love that quite a few of these renowned chemists were women. I am glad to know about these people and what they've done for science.
Debra (March 18, 2020 12:29 AM)
Coincidentally, I recently met an African American woman on the train who shared with me about her retired profession as a Chemist. During the long commute I became awe-inspired through several personal stories she shared and I think that she would be a perfect candidate to add to your list. Her name is Marilyn Wilson, currently of Columbia, S.C. if you would be so kind to consider.

M Sax (June 4, 2020 11:08 AM)
Here I miss Fletcher Henderson. He is best known as a jazz musician (one of the greatest arrangers and band leaders). But he got a degree in chemistry and maths. When he saw he could not make a decent life as a black chemist and mathematician he devoted himself to music. Which was good for jazz lovers, but a pity and a shame anyway.
Jannie S Baker (June 4, 2020 11:11 AM)
I suggest adding Dr. Betty Wright known for her work on chemical explosives while at Los Alamos National Laboratory and recipient of a governor’s award for outstanding New Mexico women.
Charles J. Patton (June 4, 2020 11:50 AM)
Please consider including Theodore "Ted" R. Williams, an exceptional analytical chemist, teacher, mentor, and human being who died in 2005 (

What a beautiful publication and honor to all these scientists that you have begun with. It is inspiring! Please consider some of our current and rising heroes in this category, Dr Rob Bryant, PhD in polymer science working at NASA Langley, Dr. Jereme Doss, PhD, Technology leader at General Plastics in Tacoma. Also, retired professor Dr John Macklin, professor At University of Washington Seattle in Raman spectroscopy. Monsongo Mouka.

How about Hosea Williams a USDA chemist at Skidaway Island, GA before joining Dr. King's civil rights movement? His is an inspiring life story.
PJ Flanigan (June 4, 2020 4:36 PM)
My inspiration to become a chemist was from Tom Smith, who at the time was a researcher at Xerox and who now works as a professor of chemistry at Rochester Institute of Technology RIT. At the time he inspired me as a child, I was unaware that so few chemists were black and did not realize that this would be a factor in the profession. Tom continues to be an enthusiastic supporter and mentor to many aspiring chemists. His contributions are Nobel, but his passion to bring fun, wonder and education to new eyes is a talent we cannot ignore.

Howard University in Washington DC has graduated the largest number of Black Ph.D.s in the US since the first graduates in 1958.The Chemistry faculty in the period of 1930-1950 were the first Black Ph.D. graduates from major research universities: R.P. Barnes (Harvard); M.D. Taylor (Chicago); K. B. Morris (Cornell); P.L. Julian (Vienna); St.E. Brady (Illinois);
L.N. Ferguson (UCBerkeley}; J. B. Morris (Penn State). An early history of the Howard Chemistry Department is on the department web page:
Richard Hill (June 6, 2020 2:41 PM)
I have only belatedly come across your impressive collection of past black chemists who deserve to be remembered. While I agree that Percy Julian should make the list, you have done a great job in finding worthy members.
Even though this is too late for inclusion in your list, let me add one more candidate that you should know about. George A. Wiley, born in 1931, received a Ph.D. in organic chemistry from Cornell 1n 1957, did a postcoc at UCLA, taught at Berkeley for two years, then moved to a tenured position at Syracuse. He became a distinguished civil rights activist. founding the Syracuse chapter of Congress of Racial Equality, then became Head of the National Welfare Rights Organization and the national commander of Movement for Economic Justice. He drowned tragically on a family sailing trip in 1972. You can find more about him in Wikipedia, in his NY Times obituary, Aug 190, 1972, in an Ebony article in April 1970, and a biography by Kotz and Kotz.
Dhrubajyoti Talukdar (June 8, 2020 2:34 PM)
What is this? I know about Organic,Inorganic and Physical chemist. What we have to do became a black chemist?
William Talbott (June 9, 2020 10:41 PM)
I also was very surprised that you did not include Percy Julian. He also appeared on a US postage stamp!
Alexander Nyuchev (June 11, 2020 6:28 AM)
Actually, Anna Volkova from Russian Empire in the middle of the 19th century was the first woman to graduate as a chemist and to publish her own chemical research, not Allice Ball.
