Einstein Observatory (EO) X ray data on supernova remnants (SNR) and radio pulsars are examined for evidence supporting the concept that neutron stars arise after supernova (SN) events. Recent data reviews have revealed that only 13 of the 140 known galactic SNR exhibit characteristics, e.g., radio pulsars, X ray binaries or synchrotron nebulae, that link neutron stars with SNR. An EO survey of radio pulsars 1 kyr-1 Myr old found eight objects, all embedded in X ray emitting nebulae. The data indicated that all the SNR and pulsar objects had about 1 percent of their spin down energy converted into synchrotron X rays. The majority of SNRs did not have X ray emitting nebulae. It is therefore concluded that only some SN events result in a neutron star, while the event may leave no remnant at all.
