Sirius: Brightest Diamond in the Night Sky
Ejnar Hertzsprung (1873-1969) took the first steps towards classifying stars on
the basis of their luminosities. As a boy in Denmark, Hertzsprung developed a
keen interest in astronomy, but following the wishes of his father he studied the

Discovering the Universe: From the Stars to the Planets
Around 1911, the Danish astronomer Ejnar Hertzsprung noticed that patterns
emerge when the luminosities of stars (or their equivalent absolute magnitudes)
are plotted against their surface temperatures (or their equivalent spectral types).

This was the first such diagram to be published, a year before Hertzsprung's first
colour-magnitude diagram. against their spectral type (using an index based on
the strength of the Balmer lines relative to the K line) [13] (see Fig. 7.5).
