Abstract
Two centuries were necessary for binaries to become, after having been unknown and ignored, one of the outstanding subjects of stellar research. This remarkable evolution has resulted now in the reversed situation with the painful question, at least for some of us: do single stars really exist?
It is recognized by everybody, that many essential properties of stars can only be obtained from observations of close and wide binaries.
It is the aim of this contribution to see how binaries can help us to better understand binaries and single stars, even if the existence of the latter is not yet definitely confirmed.
Communication presented at the International Conference on ‘Astrometric Binaries’, held on 13–15 June, 1984, at the Remeis-Sternwarte Bamberg, Germany, to commemorate the 200th anniversary of the birth of Friedrich Wilhelm Bessel (1784–1846)
