Fifty years ago, borrowing an idea from our Russian friends Guseinov and
Zeldovich, we looked for very compact stars (neutron stars and black holes, in
modern terminology) as optically-invisible components of single-line
spectroscopic binaries. We didn’t find any, but our method was very close to
the processes that soon identified neutron stars in the X-ray sources Sco X-1,
Cen X-3, and so forth, and the first persuasive black hole in Cyg X-1 (HD
226868). Here we look again at the events of 1962-72, revealing a bit more than
we knew then, and attempt to bring the story up to date with an overview of
some of the enormous richness of astronomical sources now generally thought to
consist of a neutron star or black hole, or in a few cases one of each in a
binary system.
