Last fall, the Perimeter Institute for Theoretical Physics issued five posters featuring five great women who changed science, but  whose pivotal roles have long been underplayed in favor of their much more famous male counterparts.

The response was so great—according to Perimeter, the free posters have been downloaded and displayed by schools and other institutions, and shared widely—that the Institute is going to issue a second series, to be released in time for International Women's Day on March 8.

The good news is that you can cast your vote for who should be honored this time around, Here's the list of contenders, as described by Perimeter

Vera Rubin was a legendary astronomer and physicist who uncovered the galaxy rotation problem, the strongest evidence yet for dark matter. This discovery has driven physics theory and experiment for more than 40 years.

Maryam Mirzakhani was a brilliant mathematician and a winner of the prestigious Fields Medal. Her work on geometric and dynamic complexities of curved surfaces opened new paths of research in theoretical physics, engineering, material science, pure math, and cryptography.

Claudia Alexander was a specialist in geophysics and planetary science, the last project manager of NASA’s Galileo mission to Jupiter, and served as project manager and scientist for NASA’s role in the European-led Rosetta mission.

Lise Meitner was a pioneer in the fields of radioactivity and nuclear physics. Her work helped discover and build a working understanding of nuclear fission, which led to a Nobel Prize for Otto Hahn. Albert Einstein glowingly referred to her as the “German Marie Curie.”

Vivienne Lucille Malone-Mayes was one of the first African-American women to earn a PhD in mathematics who, despite facing persistent racism, went on to have a long and distinguished research career. An active participant in the civil rights movement, Malone-Mayes fought racism and sexism throughout her career.

Cecilia Payne-Gaposchkin was an innovative astronomer whose career included studies of stellar composition, the structure of the Milky Way, and the study of more than 3 million variable stars. Her work helped bring female astronomers into the mainstream, and her PhD thesis was once called “the most brilliant ever written in astronomy.”

Henrietta Swan Leavitt was an astronomer who received little recognition in her lifetime, but forever changed our understanding of the universe. It was Leavitt’s work that allowed astronomers to measure the distance between the Earth and faraway galaxies, and made Edwin Hubble’s work on the expanding universe possible.

My own favorite is Vera Rubin—but don't let that sway you!
