At the time, they were fugitive slaves who had escaped from Kentucky to Ontario via helpers through the Underground Railroad. He was trained in Scotland as an engineer and would hold 57 patents for new inventions at the end of his career.

Happy birthday to British #engineer, #mathematician, #physicist & #inventor Hertha Ayrton (1854-1923). I’ve shown her in my #linocut with a diagram of the dividers from her 1st of 26 (!) patents, one of her diagrams about the origin & growth of ripple marks & one of her diagrams of an electric arc lamp (a subject on which she literally wrote the textbook).⁠
⁠
Born Phoebe Sarah Marks, she was the 3rd of 8 children 🧵

Linocut portrait of Hertha Ayrton, surrounded by her diagrams and some of her inventions, printed in a gradient of red to purple. Ayrton, a middle age woman with a lot of curly hair, stands with her fingertips on a tabletop, looking right, in a loose dress. Her dress is red and colours change radially out to purple. To her left and above her are a series of horizontal sections showing the formation of ripples on a beach. Above her to the right is a diagram of her dividers from her patent. To the lower right is a cross-section of an arc-lamp.

A career civil servant in Nanyang, Heng was also an #astronomer, #mathematician, #seismologist, hydraulic engineer, #inventor, geographer, cartographer, ethnographer, artist, #poet, philosopher, politician & literary scholar. He was a bit of a controversial figure politically, sparing over calendar reform & with rivals amongst the palace eunuchs. But both his poetry & famous inventions are still remembered. He also improved the Chinese approximation for pi & 🧵2/n

The 2025 Door

Right, that's a scary door to open, not that WW3 is in there, but I wonder if 2024 will be the 1938 of the 21st century
