Inspiring Women
in History & Science

A slow-built archive of women whose work was dismissed, whose pain was minimized, and whose findings reshaped what we now understand about the body, the mind, and the long arc of healing — and the heavens above us.

Henrietta Swan Leavitt

1868 — 1921
Astronomer · Mathematician · Harvard Computer

She measured the size of the universe — and was paid by the hour.

She was one of the “computers” at Harvard — women hired to do the tedious measuring of stars on glass plates, paid by the hour, forbidden from operating the telescopes themselves.

And from that quiet, underpaid work, Leavitt found something that changed everything: a way to measure the true distance to faraway stars. Her discovery gave Edwin Hubble the tool he needed to prove the universe is expanding. She handed astronomy its measuring stick — and rarely got the credit.

Some women were paid by the hour to measure the size of the cosmos.

A note from ArtfulDesign

This is part of my series on women whose contributions were dismissed, minimized, or uncredited in their own time. I’m honored to tell their stories, because they paved the way for the rest of us.
