Happy birthday to #neurologist Santiago Ramón y Cajal (1852 - 1934), here in front of Purkinje and granule cells from a pigeon, based on one of his own drawings! Cajal &Golgi won the Nobel in 1906, "in recognition of their work on the structure of the nervous system". He was as much of an artist as he was a scientist & his 100s of drawings are still used for teaching purposes.⁠

My linocut portrait of Cajal in a gradient of gold (left, where there is a table and microscope) to blue (right, where he is) . Behind him is an image based on his drawing of a Purkinje and granule cell of a pigeon in a gradient of gold to black.

Happy birthday to #biochemist Marie Maynard Daly (1921-2003), 1st Black woman to earn a PhD in #chemistry in the US! She made important research contributions to our understanding of the biochemisty of the cell nucleus & cardiovascular issues & the chemistry of histones & protein synthesis. She established that "no bases other than adenine, guanine, thymine, and cytosine were present in appreciable amounts" in DNA - #womenInSTEM #BlackInSTEM #histstm #printmaking #linocut #histmed #HeartDisease
My linocut portrait of Marie Maynard Daly in purples (she’s a young m, smiling Black woman, wearing earrings, a necklace and a dress, looking at the viewer over her shoulder). Above her to the right is an anatomical heart with a blowout diagram in a circle of a clogged artery and the cholesterol molecule all in red. Next to her on the left in blue are the molecules of the bases which make up DNA and a diagram of a human cell.

Happy birthday to Antonie van Leeuwenhoek (1632 – 1723), the Dutch scientist & progenitor of #microbiology known for his improvements to microscope tech. He was a draper in Delft, then a politician with an interest in lensmaking. Using his handmade #microscopes, he was 1st to observe microorganisms, which he called tiny animals, or "animalcules". He also made pioneering microscopic observations on muscle fibres, bacteria, coffee & … 🧵1/n

My linocut portrait of van Leeuwenhoek in burgundy wearing a wig, narrow moustache, loose robe and neck scarf, holding his invention, a microscope. He’s surrounded by his microscopic observations, “animacules”, blood vessels and more, in gold, orange, green and yellow.

An extraordinary pharmaceutical #chemist to celebrate for #BlackHistoryMonth - Alice Ball (1892-1916) who developed 1st effective treatment for #leprosy. Her research saved 1000s from exile & painful, ineffective lifelong treatment for leprosy, & she was a trailblazer for both women & Black scientists.⁠
⁠
Ball studied #chemistry at UW earning a BSc & 2nd degree in pharmacy 2 years later.
