Black scientists have made enormous contributions to humanity. With so much saddness and horror going on, we wanted to celebrate people who made the world a better place.

Here are images, quotes, and brief backgrounds on notable Black scientists.

You may use the images as you wish. Photos were all sourced from the creative commons. Links to the image sources are in the photo descriptions.

NOTE: There are many, many, many other Black STEM pioneers. We created this piece with the intention you would use and share these images. For that reason, this piece only features scientists whose images are in the public domain, so there are no copyright issues.

(September 10, 1942) – Mathematician, data analyst, and aeronautical engineer who spent most of her 40-year career researching supersonic flight and sonic booms. She was the first Black woman to be promoted to the top rank at NASA’s Langley Research Center. 


Dr. Guion S. Bluford Jr. (November 22, 1942) U.S. aerospace engineer, retired U.S. Air Force officer/fighter pilot, former NASA astronaut, and the first Black person in space.

Notable quote: “I felt an awesome responsibility, and I took the responsibility very seriously, of being a role model and opening another door to black Americans, but the important thing is not that I am black, but that I did a good job as a scientist and an astronaut. There will be black astronauts flying in later missions … and they, too, will be people who excel, not simply who are Black . . . who can ably represent their people, their communities, their country.”
