Women who changed the world: Henrietta Swan Leavitt (1868-1921)

"Henrietta Swan Leavitt (1868-1921) was a U.S. astronomer whose work guided the field to understand distances in the universe. At a time when women's contributions were undervalued, attributed to male scientists, or ignored, Leavitt's findings were seminal to astronomy as we understand it today.

Leavitt's careful work measuring the brightness of variable stars, forms the basis of astronomical understanding of such topics as distances in the universe and the evolution of stars. Such luminaries as astronomer Edwin P. Hubble praised her, stating that his own discoveries rested largely on her accomplishments."
