This paper describes the work of Bertil Lindblad (1895-1965) up to the time when he took an increasing interest in galactic dynamics and when he also became director of the Stockholm Observatory with the task of creating a new observatory in Saltsjöbaden. The paper relates how the two-dimensional classification of stellar spectra at very low dispersion in terms of temperature and luminosity developed out of measurements of effective wavelengths of stars. From this emanated the scheme of quantitative classification of objective prism spectra by which Lindblad's collaborators derived important results concerning the structure of the Milky Way galaxy. The paper ends when Lindblad's main research took new directions and tasks within national and international science gave new directions to his life.
