The Dominion Astrophysical Observatory and its 1.8m telescope came into existence largely as a result of J.S. Plaskett's success in studying spectroscopic binaries with the much smaller Ottawa telescope. The major programmes in Victoria, in addition to the study of binaries, were the study of galactic structure and rotation and the study of hot (OB) stars. Both of these, however, involved as by-products the discovery of spectroscopic binaries, so that a major part of the new observatory's work was devoted to these objects. In this, the DAO was following the example of other large west-coast observatories (Lick and Mount Wilson) and these three together became world leaders in the then new study of spectroscopic binaries. The work has remained a traditional area of DAO efforts right down to the present day. Later, the David Dunlap Observatory, with its very similar equipment, also joined in the now well-established Canadian tradition and has also continued it into modern times. Binary studies are at the very base of modern astrophysics and, in the early decades of this century, were a natural area of specialization for an observatory devoted to that area of astronomy. Indeed, the study of binaries and the emergence of astrophysics are closely linked.
