  After beginning with a short historical review of the concept of displaced
(coherent) and squeezed states, we discuss previous (often forgotten) work on
displaced and squeezed number states. Next, we obtain the most general
displaced and squeezed number states. We do this in both the functional and
operator (Fock) formalisms, thereby demonstrating the necessary equivalence. We
then obtain the time-dependent expectation values, uncertainties,
wave-functions, and probability densities. In conclusion, there is a discussion
on the possibility of experimentally observing these states.
