The birth-rate of radio pulsars in globular clusters (GCs) is thought to be a factor of 10 to 100 times greater than that of their candidate progenitors, low-mass X-ray binaries (LMXBs) of canonical lifetime 100 million to a billion yr. This apparent discrepancy would be removed either if there were more rapid accretion of mass onto the primary in the late stages of LMXB evolution or if there occurred accretion-induced collapse of white dwarfs in binaries with wide orbits. But the available data indicate that GC pulsars cannot be formed by either of these mechanisms alone. Here it is suggested that both processes may be necessary to some extent, the corollary of which is that GC pulsars may have at least two distinct classes of progenitors. Many solitary and binary pulsars with short orbital periods may have descended from rapidly evolving LMXBs, whereas others, especially those with long periods, may have formed from binaries that undergo nuclear evolution of the secondary and eventual accretion-induced collapse of the white-dwarf primary.
