He spent nearly his entire career at Princeton University, starting as a student and eventually becoming a professor and director of the Princeton Observatory. He worked alongside other notable astronomers like Harlow Shapley early in his career.
What was Russell's theory on the source of a star's energy?
Before nuclear fusion was understood, Russell proposed that stars were powered by the contraction of their own massive gravity. While later proven incorrect, this was a leading theory in the early 20th century.
Did Henry Norris Russell work on calculating the chemical composition of stars?
