Happy birthday to #mathematician & geodesist Gladys West (née Brown in 1930)! Shown with satellite tracks & 3 satellites important to her career: Seasat, GEOS-3 & a GPS satellite. Her work, using math to precisely model the shape of Earth, laid the groundwork for GPS! Born to sharecropper parents in Virginia, she graduated with a Math BSc in ‘52 then MSc at VSU in ‘55. 🧵1/n
