Robert "The Bobby Yaga" McNees @mcnees.bsky.social · 07/01/2026Physicist Marguerite Perey discovered Francium #OTD in 1939. It was the last element to be found in a naturally occurring state, rather than synthesized by humans. 🧪 ⚛️ 👩🔬 Image: Musée Curie/ACJC Collection 7790188 0
P'rfesser @prfesser.bsky.social · 08/01/2026Quite the achievement when it's considered that the total amount of naturally-occuring francium in the Earth's crust is about...one ounce (28 grams). 020 0
Virginia Hall @fuckthepedogarchy.bsky.social · 08/01/2026What's more amazing is that a man didn't steal the glory of the discovery. Because that's what usually happened when a woman discovered something. 000 0

Robert "The Bobby Yaga" McNees @mcnees.bsky.social · 07/01/2026Perey hoped that Francium would prove useful in the early diagnosis of cancer, because of its tendency to accumulate in cancerous tissue more rapidly than in healthy tissue. But it was too dangerous; Perey herself developed cancer as a result of her work. www.nytimes.com/2014/12/07/m... 0171 0
