Annie Scott Dill Maunder was a Northern Irish astronomer and mathematician who studied the mathematical tripos at Cambridge then worked at the Royal Observatory Greenwich. She was the first to find evidence of the movement of sunspot emergence from the poles toward the equator over the sun’s 11-year cycle.
Ida Rhodes was born in the Ukraine but emigrated to the United States as a teenager. She studied mathematics and had a variety of jobs before joining the Mathematical Tables Project in New York City. She did important work on the development of computers.
Maryna Viazovska is a Ukrainian mathematician who is professor at the Chair of Number Theory at the Institute of Mathematics of the École Polytechnique Fédérale de Lausanne in Switzerland. She solved the sphere-packing problem in dimension 8 and, in collaboration with others, the sphere-packing problem in dimension 24.
Svetlana Jitomirskaya is a Ukranian-born American mathematician who is known for her work on dynamical systems and mathematical physics.
Irmgard Flügge-Lotz worked on numerical methods for solving differential equations especially in fluid dynamics.
Johanna Weber was a mathematician who began her career in Germany but continued after World War II in England. She worked on aerodynamics and played a large part in designing the wings of Concorde and of the Airbus.
