Answer
The Harvard Classification Scheme was aimed at classifying stars by temperature and spectral types. The scheme was developed by Annie Jump Cannon and Edward C. Pickering in the early 20th century. It is based on the observation that the spectra of stars can be classified into a few distinct types, each of which is associated with a particular temperature range.
