On this day in 1887 - October 25th - American astronomer Henry Norris Russell was born.
Russell was one of the major figures of early 20th century astronomy. He's best known today for his part in creating what's now called the Hertzsprung-Russell diagram which demonstrates stellar evolution. (Danish astronomer Ejnar Hertzsprung independently made the same discovery.)
