#10 Henrietta Leavitt
Henrietta Leavitt is another unknown woman scientist who has made revolutionary discoveries in physics and astrology. This American scientist is the one who changed the perspectives about the universe which paved the way for other scientists like Edward Hubble to make detailed studies and findings about the universe. Many male scientists used her discoveries to substantiate their own discoveries but none of them gave any credit to Leavitt. One of her notable discoveries includes the period-luminosity relationship using which many other scientists were able to determine the distance between a star and the earth.
