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, 🧵

Happy birthday to #physicist Harriet Brooks (1876 - 1933) who discovered atomic recoil, Radon & recognized radioactive elements could undergo chains of transmutations into a series of new elements. #nuclear #physics

She was Rutherford’s 1st grad student at McGill. After publishing her results in 1899 she completed her MSc in 1901 on “Damping of Electrical Oscillations,” before embarking on #radioactivity research.⁠ 🧵
