It is suggested that the pulsars PSR 1952 + 29 and PSR 1929 + 10 might have originated in a binary system which was disrupted by a supernova explosion less than a million years ago. Examination of the proper motion of the two pulsars shows that they might have at one time been close to each other. Possible galactic coordinates for the coincidence are selected, and the velocities required for the pulsars to obtain their current position are calculated. It is proposed that the explosion occurred approximately 0.6 Myr ago and that PSR 1929 + 10 is the neutron star that was formed in the explosion. PSR 1952 + 29 would have been a neutron star in orbit around the more massive star which gave rise to PSR 1929 + 10. It is pointed out that this hypothesis provides a link between X-ray binary systems and radio pulsars.
