Black History Month 2021 - Notable Scientists Throughout History

Black History Month is a time dedicated to celebrating the contributions of Black people to the United States. Originally beginning in 1926 as a week-long event, it extended to a full month in 1976.  All February long, we celebrated Black scientists and their significant contributions to science. Here is some more information about the scientists we shared on social media, and a few extra scientists too!

If, like us, this short list of amazing Black Scientists isn’t long enough to sate your inspiration, here are some other great science communicators who have highlighted their favorite Black Scientists for Black History Month:

Physicist and teacher Dr. Edward Bouchet (1852-1918) was the first Black person to earn a PhD in America in 1876. An active and passionate advocate for STEM education, Bouchet pushed against the notion that Black Americans should avoid academic and scientific pursuits and urged his schools to establish more laboratory spaces for hands-on science learning. Now, the American Physical Society awards the Edward A. Bouchet Award to physicists for their contributions to the field, and Yale, from which he earned his PhD, established the Edward A. Bouchet Graduate Honor Society.

George Washington Carver (1860s-1943) never received a doctorate degree, despite being called “Dr.” He was awarded an honorary doctorate from both Simpson College and Selma University. Notwithstanding, he was the head of Tuskegee Institute’s Agriculture Department and taught for over 40 years. Notably, he developed a crop rotation system to improve cotton farming by suggesting rotating in sweet potatoes, peanuts, or soybeans to return nitrogen to the soil; this procedure, and the theory behind it, of rotating nitrogen-rich crops into agricultural fields is still in practice today. Additionally, he developed an agricultural extension program to educate farmers on the rotation technique and spread nutritional recipes using the new crops, most notably peanut recipes. To further this endeavor, Carver established his own industrial research laboratory to identify new uses of the rotating crops to increase their popularity. While incorrectly connected with the rise of peanut butter, he did develop over 300 peanut products including Worcestershire sauce.
