The progenitor of the binary pulsar PSR 1913 + 16 (period 0.059 sec) is proposed to have been either a cataclysmic variable binary or an evolved massive X-ray binary. A range of satisfactory initial binary periods and masses are obtained for both cases assuming that a small 'kick' was imparted by a slightly asymmetric supernova explosion, although such an explosion is not absolutely necessary in the second case. In the first scenario, the companion of the pulsar is thought to be a temporarily undersized lower main-sequence star stripped of its envelope by the explosion, and the apsidal motion period of the system is predicted to be a few months. It is shown that such a system may become a low-mass X-ray binary similar to Sco X-1 upon reexpansion of the companion. In the second scenario, the companion is thought to be a collapsed star, and the system would have only a small general relativistic apsidal motion. Evolution from a system like HZ 29 is found to be impossible.
