Clarice Phelps may have been the first African-American woman to help discover a chemical element. For Wikipedia, that wasn’t enough.
You’ve probably never heard of Clarice Phelps. If you were curious, you might enter her name into Google. And, if you had done so anytime between September of last year and February of this year, you would likely have found her Wikipedia entry. The nuclear scientist is thought to be the first African-American woman to help discover a chemical element; she was part of the Oak Ridge National Laboratory team that purified the radioactive sample of berkelium-249 from which the new element, tennessine, was created. But on February 11, 2019, in the middle of Black History Month and on the International Day of Women and Girls in Science, Phelps’s page was deleted. The optics, as they say, weren’t good.
