In 1911, a Danish astronomer named Ejnar Hertzsprung plotted the absolute magnitude against color for a collection of stars and noticed that there was a strong correlation between these two variables. Independently, an American astronomer named Henry Russell produced a similar plot.

The Hertzsprung-Russell (HR) diagram is a plot of stellar luminosity against an indicator of stellar surface temperature (color or spectral type). It is motivated by the blackbody luminosity formula L = (4`pi'`sigma') R 2 T 4. From the HR diagram of nearby stars, we learn of the existence of a main sequence, red giants, and white dwarfs.
