Hertzsprung–Russell diagram
This minor planet was named in memory of Danish chemist and astronomer Ejnar Hertzsprung (1873–1967), best known for the famous Hertzsprung–Russell diagram, a spectral classification system for stars he developed jointly with Russel, after whom the asteroid was named. From 1934 to 1945, Hertzsprung was the head of the Leiden Observatory in the Netherlands.
