The main sequence - the region across the middle of the diagram.
Enjar Hertzsprung lived in 1873-1967 and Henry Russell lived in 1877-1957. They were scientists who worked separtely. They found the same answer about the temperature and color of stars. The diagram that they made is called the Hertzsprung-Russell diargram. It shows the connection between surface temperature and color.The discoverers of the famous Hertzsprung-Russel diagram (HR diagram), which turned out to be an important tool for the analysis of stars.
increase in absolute brightness as they increase in temperature.Increase in brightness as they increase in temperature
I believe you are thinking of a Hertzsprung-Russell diagram, but this denotes the relationship between a stars luminosity and it's spectral class.It has nothing to do with the life cycle of a star.See related questions for more information
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
The diagram was created by Ejnar Hertzsprung and Henry Norris Russell aound 1910.
The Hertzsprung-Russell diagram graphs stars' brightness and corresponding temperatures in addition to their classifications. The stars' colors are due to their temperatures.

The Hertzsprung-Russell diagram, or H-R diagram, was created in 1911 by Ejnar Hertzsprung and Henry Norris Russell. They plotted the luminosity of stars against their surface temperature to classify and study stellar populations. This diagram revolutionized our understanding of stars and their life cycles.

This type of diagram is often called a Hertzprung-Russell diagram after two astronomers.
