He rode a caiman like a horse. He climbed St. Peter's Basilica to leave a glove on top, then climbed back up to fetch it when the Pope demanded its removal. He dangled his bare foot from a hammock so vampire bats could feed on his toes. Charles Waterton: the barefoot squire who taught the man who taught Darwin.

Happy birthday #entomologist & scientific illustrator Maria Sibylla Merian (1647-1717)! Her stepdad Jacob Marrel & students trained her as an artist. She began painting insects & plants by 13. She wrote, “I spent my time investigating insects. [...] I realized that other caterpillars produced beautiful butterflies or moths, and that silkworms did the same. This led me to collect all the caterpillars I could find in order to see how they changed”.⁠

He figured out that all matter is made of tiny indivisible particles moving through empty space. No lab, no instruments — just thinking. His neighbors thought he was insane and called a doctor. The doctor sided with him. Democritus: the man who got the universe right and left almost nothing behind.

TFW you’re writing about Charles Darwin (obviously), and you type the words, “He also showed how…”, and you realise you need to read up a bit more on this, and, a week later, you’ve read and made copious notes on his book about the fertilisation of orchids, and you now feel ready to finish your damn sentence. #AmWriting #HistSci

Happy birthday to French mathematician, physicist and philosopher Marie-Sophie Germain (1776 – 1831), known as Sophie. She taught herself mathematics using books in her father’s library and by corresponding with leading mathematicians of her day, including Lagrange, Legendre and Gauss, initially using the pseudonym Monsieur LeBlanc. Her work on elasticity theory won her the grand prize from the Paris Academy of Sciences. 🧵
