Happy birthday to #astronomer Henrietta Swan Leavitt (1868-1921) who set the scale of our Universe. My portrait of Leavitt is printed in silvery lavender ink on Japanese kozo (or mulberry paper). Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco, 🧵

"Jan 15: 1884 I like to think of Father in all ways I can so as to keep the image of him before me to the end of my life. I like to remember the sound of his walking stick on the gravel walk in the morning before breakfast as he came to the house after his early walk. I like the vision of him at the further end of the sandwalk in his hat & cloak walking to meet me, when he met me he would stop still a yard or so off to listen to what I had to say leaning on his stick, and his pale tired face would light up with a delightful smile of sympathy — I like to remember the many happy turns I have taken with him in the sandwalk, and this brings to my memory the walks before breakfast in the dusk I took with him sometimes down to High Elms Lane when I was a school boy. I can never forget the keen intentness with which he would watch for or look at any rare bird. I like to think of the brisk cheerful way he would talk when I sometimes (too seldom alas) came down to his early breakfast. I like to think of him sitting in his big arm chair in the drawing room talking & ..."

Aktuelles Heft:
#WerkstattGeschichte 91 "körpermaße"

Im Thementeil, hg. v. @connyaust.bsky.social‬, geht es darum, wie Vorstellung, Wahrnehmung & Vermessung von Körpern v.a. im 18./19. Jh. dazu beitrugen, geschlechtsspezifische & rassistische Differenzkategorien herzustellen & Körpereigenschaften zu essenzialisieren?

Frontcover von WerkstattGeschichte 91 unter Verwendung eines Ausschnitts einer Übersichtstafel, auf der Fotos mit Beispielen für verschiedene physiognomische Merkmale zusammengestellt sind. Der Ausschnitt zeigt vor allem zwei S/W-Porträtaufnahmen eines männlichen Gesichts (frontal und seitlich), auf denen Buchstaben und Linien unterschiedliche Merkmale und Maße markieren und auf die nicht abgebildete Legende verweisen; am oberen Rand sind teils abgeschnitten sechs kleinere Aufnahmen zu sehen, die unterschiedliche Halsformen, und zwei, die unterschiedliche Schulterhaltungen darstellen. (Der Ausschnitt stammt aus: Tableau synoptic des traits physionomiques: pour servir a l’étude du »portrait parlé«, Alphonse Bertillon, ca. 1909, Gelatin silver print, metmuseum.org).

Skulls once subject to racist study in Germany are laid to rest in New Orleans
"Researchers presume many of the 19 people had been enslaved, later moved freely after the Civil War, and eventually fell ill or were institutionalized in asylums before landing at Charity Hospital in New Orleans"

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 🧵1/n

Square linocut print on white paper of seismologist Inge Lehmann in a fur coat, silk scarf and dapper hat, in dark grey-teal ink overprinted with her diagram of the cross-section of the Earth in orange and red from her P’ paper, showing the mantle, outer core and inner core, an earthquake epicentre marker E and labelled ray paths through the Earth.

The Sad Story of Darwin’s Self-Procleimed “Stupidest” Child
"Leonard Darwin had a lot to live up to. He was the son of the legendary Charles, and several siblings proved to be brilliant scientists as well...In his fifties, he pronounced his life a “failure.” But in his sixties, he finally found his calling—the dark pseudoscience of eugenics, a field he embraced in part to prove that he wasn’t the failure he imagined"

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.

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!
