About Henrietta Hill Swope
- Henrietta Hill Swope (October 26, 1902 – November 24, 1980) was an American astronomer who studied variable stars.
- In particular, she measured the period-luminosity relation for Cepheid stars, which are bright variable stars whose periods of variability relate directly to their intrinsic luminosities.
- Their measured periods can therefore be related to their distances and used to measure the size of the Milky Way and distances to other galaxies.
