Alice Ball, MS

Lived: 1892 – 1916

Fields of Activity: Chemistry, Medicine

Biochemist Alice Ball earned Bachelor of Science degrees in pharmaceutical chemistry and pharmacy from the University of Washington in 1910 and 1914, respectively. In 1915, she earned a Master’s Degree from the University of Hawaii, becoming the first woman, the first Black woman, and the first African American person to do so.

Inspired by her research, the Assistant Surgeon at the Leprosy Investigation Station of the U. S. Public Health Service in Hawaii asked her to research the chemical properties of Chaulmoogra oil, with the hope of developing a treatment for the disease. Ball figured out how to turn the oil into an effective injectable treatment using the “Ball Method.”

Ball’s product would remain the only treatment for leprosy until 1940.

Patricia Bath, MD

Lived: 1942 – 2019

Field of Activity: Medicine

If you can see clearly, you may have Dr. Patricia Bath to thank.

Dr. Patricia Era Bath was an ophthalmologist, inventor, and philanthropist. After receiving her MD from Howard University College of Medicine in Washington, DC, she became a researcher in pediatric surgery.

After the assassination of Martin Luther King, Jr. in 1968, Bath dedicated herself to economic justice, working with the Poor People’s Campaign.

Following an internship at Harlem Hospital Center, where she observed a disproportionate number of blind patients, she accepted a fellowship from Columbia University to study eye care services at Harlem Hospital, which did not have any staff ophthalmologists.

Her research convinced Columbia University professors to operate on blind patients at Harlem Hospital Center for no charge. Bath was among the doctors who performed the first eye surgery there.

Bath also invented and patented the laser phaco probe, which improved laser cataract surgery. She holds four patents related to cataract surgery. Bath also founded the American Institute for the Prevention of Blindness.

Still have questions? We have answers!

What Is the Profession of the First Black Female Scientist?

That’s a difficult question!

Sarah Breedlove (Madame CJ) Walker (1867 – 1919) is known for creating beauty products for African American women, but those products were developed using a knowledge of chemistry that Walker gained while working for a pharmacist. This very early Black female scientist was an entrepreneur with a background in chemistry and pharmacy.

What Is One of the First Inventions by a Black Female Scientist?

Biochemist Alice Ball (1892-1916) invented a method for turning Chaulmoogra oil into an injectable, effective treatment for leprosy.

What Is One of the Most Important Achievements for Black Female Scientists?

With so many incredible achievements, it’s difficult to just choose one!

For our money, the work of Dr. Jane Wright and Dr. Jewel Plummer Cobb in cancer treatment is one of the achievements that has touched the most lives and will continue to do so. If cancer is ever fully eradicated, it will be largely due to their pioneering research in this field.
