It's #WorldBeeDay! 
This gorgeous gynandromorph potter flower bee is described in a 1845 article in The Zoologist by English entomologist Frederick Smith. It's pictured from above (left) and below (right).

Happy birthday to Danish #seismologist Inge Lehmann (1888 – 1993) who demonstrated that the Earth’s core is not a single molten sphere, but contained an inner solid core, in ‘36. She was a pioneer #womanInScience, a brilliant seismologist & lived to be 105.
As she first postulated, the #earth has roughly 3 equal concentric sections: mantle, liquid outer core & solid inner core. The crust, on which we live is merely

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
Happy birthday to #mathematician Felix Klein (1849-1925). This is a hand-carved and hand-printed image of the famous mathematical object, the Klein bottle, printed in a gradient of pale yellow-green to darker blue-green on paper 8” by 8” (20.3 cm by 20.3 cm). First described by mathematician Felix Klein in 1882, this object has a single surface, rather like a 3D version of a Möbius strip.

Happy Easter to all who celebrate! 
No cute lambs or bunnies in my files, I'm afraid. I do, however, have a *lot* of queer chickens. This is Hector, a 'hen-cock' pictured in the Sporting Magazine in March 1833 and mentioned by Charles Darwin in his 1868 book The Variation of Animals and Plants under Domestication!

Happy birthday to Canadian 
geneticist Irene Ayako Uchida (1917-2013)! In my #linocut Uchida is shown surrounded by chromosones, with anomalies (shown with pink arrows) due to radiation exposure, based on one of her research papers. A strand of DNA is hidden in the image (as her watchband).
Uchida didn’t set out to be a scientist. She was studying English literature at UBC, before she was interned 1/n

Der japanische Mediziner & Anthropologe Buntaro Adachi starb heute vor 80 Jahren. Er untersuchte als erster Zusammenhänge von Ohrenschmalzkonsistenz & Achselschweißgeruch – kein Aprilscherz! Was dies mit "Rassenphysiologie" zu tun hat, erklärt:

Im Thementeil, hg. v. Cornelia Aust, geht es diesmal um das Vermessen & Vergleichen von Körpermerkmalen v.a. im 18./19. Jh. Wie trug dies dazu bei, geschlechtsspezifische & rassistische Differenz herzustellen und so Körpereigenschaften zu essenzialisieren?
Happy birthday to Wilhem Röntgen (1845-1923), the German physicist who discovered x-rays and earned the Nobel Prize for physics in 1901. I’ve depicted him in this thermochromic portrait at work, studying this mysterious, newly discovered, invisible form of light, based on a photograph of him in his lab, using a Crookes tube to produce x-rays. The form of the print mimics the nature of his discovery -

Lynn Margulis was born OTD in 1938. At 29, she published her theory that eukaryotes had evolved via endosymbiosis, after having it rejected by at least 15 other journals.

I knew, of course, that William Whewell first coined the word “scientist,” but I had no idea that the idea remained so controversial that Nature was still weighing in on the appropriateness of the term at least as late as 1925. https://www.nature.com/articles/115253a0.pdf #HistSTM #PhilSci #STS
It’s #BlackHistoryMonth so it’s a good time to celebrate the extraordinary mathematician and NASA scientist Katherine Johnson (née Coleman; August 26, 1918 – February 24, 2020). One of the first Black women employed as a NASA scientist (and its predecessor NACA), she was known for her mastery of complex manual calculations of orbital mechanics and played a pivotal role in the success of

Happy birthday to trailblazing #programmer & #computer scientist, Beatrice “Trixie” Worsley (1921-1972). My #linocut shows Worsley seated at the first computer in Canada, the FERUT (which she named) & a flow diagram of one of her programs.
Trixie Worsley earned one of the first doctorates in computer science anywhere, & was supervised by Douglas Hartree and Alan Turing at Cambridge. 1/n
Haven't been here in a while. (Well, I have, but sporadically.) There has been life... and an exciting "exchange" semester to TU Dresden's @IfG_TUD. Hope I can be round here a little more often. Soon fully back to @histKIT.
Perhaps, I even find time to write a little on my research on children's mobility history and tooting from #t2m conference next week.
Are you still here, @histodons?

Happy birthday to trailblazing American computer scientist Frances Elizabeth Allen (1932 – 2020) who made foundational contributions to optimizing compilers, optimizing programs and parallel computing. She was the first woman to become an IBM Fellow, where she worked from 1957 to 2002 and as an emeritus fellow afterwards. She was the first woman to win the Turing Prize.

A nice review of #OilBeach has come in from Choice (American Library Association):
"harbors are regions of complex and global interactions between humans and their environment, complicating #biodiversity #conservation and restoration efforts... Highly recommended."
