This man's namesake Variable Nebula is a reflection nebula in Monoceros, while with Sandage he is the namesake of a type of extremely massive, luminous hypergiant variable star. In 1925 he devised a widely used system for classifying galaxies using his famous "tuning-fork" diagram, and by 1929 his work at the Mount Wilson observatory produced good distance measurements for over twenty galaxies, which he compared to their velocities to determine that they were receding with speeds that increased with their distance. FTP, who was this astronomer whose undetermined namesake constant governs this recession?
